  3. PyTorch's flexibility and dynamic nature make it a popular choice for deep learning researchers and practitioners. Developed by Google, XLA is a specialized compiler designed to optimize linear algebra computations – the foundation of deep learning models. PyTorch/XLA offers the best of both worlds: the user experience and ecosystem advantages of PyTorch, with the compiler performance of XLA. PyTorch/XLA stack diagram We are excited to launch PyTorch/XLA 2.3 this week. The 2.3 release brings with it even more productivity, performance and usability improvements. Why PyTorch/XLA? Before we get into the release updates, here’s a short overview of why PyTorch/XLA is great for model training, fine-tuning and serving. The combination of PyTorch and XLA provides key advantages: Easy Performance: Retain PyTorch's intuitive, pythonic flow while gaining significant and easy performance improvements through the XLA compiler. For example, PyTorch/XLA produces a throughput of 5000 tokens/second while finetuning Gemma and Llama 2 7B models and reduces the cost of serving down to $0.25 per million tokens. Ecosystem advantage: Seamlessly access PyTorch's extensive resources, including tools, pretrained models, and its large community. These benefits underscore the value of PyTorch/XLA. Lightricks shares the following feedback on their experience with PyTorch/XLA 2.2: "By leveraging Google Cloud’s TPU v5p, Lightricks has achieved a remarkable 2.5X speedup in training our text-to-image and text-to-video models compared to TPU v4. With the incorporation of PyTorch XLA’s gradient checkpointing, we’ve effectively addressed memory bottlenecks, leading to improved memory performance and speed. Additionally, autocasting to bf16 has provided crucial flexibility, allowing certain parts of our graph to operate on fp32, optimizing our model’s performance. The XLA cache feature, undoubtedly the highlight of PyTorch XLA 2.2, has saved us significant development time by eliminating compilation waits. These advancements have not only streamlined our development process, making iterations faster but also enhanced video consistency significantly. This progress is pivotal in keeping Lightricks at the forefront of the generative AI sector, with LTX Studio showcasing these technological leaps." - Yoav HaCohen, Research team lead, Lightricks What's in the 2.3 release: Distributed training, dev experience, and GPUs PyTorch/XLA 2.3 keeps us current with PyTorch Foundation's 2.3 release from earlier this week, and offers notable upgrades from PyTorch/XLA 2.2. Here's what to expect: 1. Distributed training improvements SPMD with FSDP: Fully Sharded Data Parallel (FSDP) support enables you to scale large models. The new Single Program, Multiple Data (SPMD) implementation in 2.3 integrates compiler optimizations for faster, more efficient FSDP. Pallas integration: For maximum control, PyTorch/XLA + Pallas lets you write custom kernels specifically tuned for TPUs. 2. Smoother development SPMD auto-sharding: SPMD automates model distribution across devices. Auto-sharding further simplifies this process, eliminating the need for manual tensor distribution. In this release, this feature is experimental, supporting XLA:TPU and single-host training. PyTorch/XLA autosharding architecture Distributed checkpointing: This makes long training sessions less risky. Asynchronous checkpointing saves your progress in the background, protecting against potential hardware failures. 3. Hello, GPUs! SPMD XLA: GPU support: We have extended the benefits of SPMD parallelization to GPUs, making scaling easier, especially when handling large models or datasets. Start planning your upgrade PyTorch/XLA continues to evolve, streamlining the creation and deployment of powerful deep learning models. The 2.3 release emphasizes improved distributed training, a smoother development experience, and broader GPU support. If you're in the PyTorch ecosystem and seeking performance optimization, PyTorch/XLA 2.3 is worth exploring! Stay up-to-date, find installation instructions or get support on the official PyTorch/XLA repository on GitHub: https://github.com/pytorch/xla PyTorch/XLA is also well-integrated into the AI Hypercomputer stack that optimizes AI training, fine-tuning and serving performance end-to-end at every layer of the stack: Ask your sales representative about how you can apply these capabilities within your own organization.

It has a nice web management interface and a lot of features. One of the most amazing features of Proxmox VE is that it can passthrough PCI/PCIE devices (i.e. an NVIDIA GPU) from your computer to Proxmox VE virtual machines (VMs). The PCI/PCIE passthrough is getting better and better with newer Proxmox VE releases. At the time of this writing, the latest version of Proxmox VE is Proxmox VE v8.1 and it has great PCI/PCIE passthrough support. In this article, I am going to show you how to configure your Proxmox VE 8 host/server for PCI/PCIE passthrough and configure your NVIDIA GPU for PCIE passthrough on Proxmox VE 8 virtual machines (VMs). Table of Contents Enabling Virtualization from the BIOS/UEFI Firmware of Your Motherboard Installing Proxmox VE 8 Enabling Proxmox VE 8 Community Repositories Installing Updates on Proxmox VE 8 Enabling IOMMU from the BIOS/UEFI Firmware of Your Motherboard Enabling IOMMU on Proxmox VE 8 Verifying if IOMMU is Enabled on Proxmox VE 8 Loading VFIO Kernel Modules on Proxmox VE 8 Listing IOMMU Groups on Proxmox VE 8 Checking if Your NVIDIA GPU Can Be Passthrough to a Proxmox VE 8 Virtual Machine (VM) Checking for the Kernel Modules to Blacklist for PCI/PCIE Passthrough on Proxmox VE 8 Blacklisting Required Kernel Modules for PCI/PCIE Passthrough on Proxmox VE 8 Configuring Your NVIDIA GPU to Use the VFIO Kernel Module on Proxmox VE 8 Passthrough the NVIDIA GPU to a Proxmox VE 8 Virtual Machine (VM) Still Having Problems with PCI/PCIE Passthrough on Proxmox VE 8 Virtual Machines (VMs)? Conclusion References Enabling Virtualization from the BIOS/UEFI Firmware of Your Motherboard Before you can install Proxmox VE 8 on your computer/server, you must enable the hardware virtualization feature of your processor from the BIOS/UEFI firmware of your motherboard. The process is different for different motherboards. So, if you need any assistance in enabling hardware virtualization on your motherboard, read this article. Installing Proxmox VE 8 Proxmox VE 8 is free to download, install, and use. Before you get started, make sure to install Proxmox VE 8 on your computer. If you need any assistance on that, read this article. Enabling Proxmox VE 8 Community Repositories Once you have Proxmox VE 8 installed on your computer/server, make sure to enable the Proxmox VE 8 community package repositories. By default, Proxmox VE 8 enterprise package repositories are enabled and you won’t be able to get/install updates and bug fixes from the enterprise repositories unless you have bought Proxmox VE 8 enterprise licenses. So, if you want to use Proxmox VE 8 for free, make sure to enable the Proxmox VE 8 community package repositories to get the latest updates and bug fixes from Proxmox for free. Installing Updates on Proxmox VE 8 Once you’ve enabled the Proxmox VE 8 community package repositories, make sure to install all the available updates on your Proxmox VE 8 server. Enabling IOMMU from the BIOS/UEFI Firmware of Your Motherboard The IOMMU configuration is found in different locations in different motherboards. To enable IOMMU on your motherboard, read this article. Enabling IOMMU on Proxmox VE 8 Once the IOMMU is enabled on the hardware side, you also need to enable IOMMU from the software side (from Proxmox VE 8). To enable IOMMU from Proxmox VE 8, you have the add the following kernel boot parameters: Processor Vendor Kernel boot parameters to add Intel intel_iommu=on, iommu=pt AMD iommu=pt To modify the kernel boot parameters of Proxmox VE 8, open the /etc/default/grub file with the nano text editor as follows: $ nano /etc/default/grub At the end of the GRUB_CMDLINE_LINUX_DEFAULT, add the required kernel boot parameters for enabling IOMMU depending on the processor you’re using. As I am using an AMD processor, I have added only the kernel boot parameter iommu=pt at the end of the GRUB_CMDLINE_LINUX_DEFAULT line in the /etc/default/grub file. Once you’re done, press <Ctrl> + X followed by Y and <Enter> to save the /etc/default/grub file. Now, update the GRUB boot configurations with the following command: $ update-grub2 Once the GRUB boot configurations are updated, click on Reboot to restart your Proxmox VE 8 server for the changes to take effect. Verifying if IOMMU is Enabled on Proxmox VE 8 To verify whether IOMMU is enabled on Proxmox VE 8, run the following command: $ dmesg | grep -e DMAR -e IOMMU If IOMMU is enabled, you will see some outputs confirming that IOMMU is enabled. If IOMMU is not enabled, you may not see any outputs. You also need to have the IOMMU Interrupt Remapping enabled for PCI/PCIE passthrough to work. To check if IOMMU Interrupt Remapping is enabled on your Proxmox VE 8 server, run the following command: $ dmesg | grep 'remapping' As you can see, IOMMU Interrupt Remapping is enabled on my Proxmox VE 8 server. NOTE: Most modern AMD and Intel processors will have IOMMU Interrupt Remapping enabled. If for any reason, you don’t have IOMMU Interrupt Remapping enabled, there’s a workaround. You have to enable Unsafe Interrupts for VFIO. Read this article for more information on enabling Unsafe Interrupts on your Proxmox VE 8 server. Loading VFIO Kernel Modules on Proxmox VE 8 The PCI/PCIE passthrough is done mainly by the VFIO (Virtual Function I/O) kernel modules on Proxmox VE 8. The VFIO kernel modules are not loaded at boot time by default on Proxmox VE 8. But, it’s easy to load the VFIO kernel modules at boot time on Proxmox VE 8. First, open the /etc/modules-load.d/vfio.conf file with the nano text editor as follows: $ nano /etc/modules-load.d/vfio.conf Type in the following lines in the /etc/modules-load.d/vfio.conf file. vfio vfio_iommu_type1 vfio_pci Once you’re done, press <Ctrl> + X followed by Y and <Enter> to save the changes. Now, update the initramfs of your Proxmox VE 8 installation with the following command: $ update-initramfs -u -k all Once the initramfs is updated, click on Reboot to restart your Proxmox VE 8 server for the changes to take effect. Once your Proxmox VE 8 server boots, you should see that all the required VFIO kernel modules are loaded. $ lsmod | grep vfio Listing IOMMU Groups on Proxmox VE 8 To passthrough PCI/PCIE devices on Proxmox VE 8 virtual machines (VMs), you will need to check the IOMMU groups of your PCI/PCIE devices quite frequently. To make checking for IOMMU groups easier, I decided to write a shell script (I got it from GitHub, but I can’t remember the name of the original poster) in the path /usr/local/bin/print-iommu-groups so that I can just run print-iommu-groups command and it will print the IOMMU groups on the Proxmox VE 8 shell. First, create a new file print-iommu-groups in the path /usr/local/bin and open it with the nano text editor as follows: $ nano /usr/local/bin/print-iommu-groups Type in the following lines in the print-iommu-groups file: #!/bin/bash shopt -s nullglob for g in `find /sys/kernel/iommu_groups/* -maxdepth 0 -type d | sort -V`; do echo "IOMMU Group ${g##*/}:" for d in $g/devices/*; do echo -e "\t$(lspci -nns ${d##*/})" done; done; Once you’re done, press <Ctrl> + X followed by Y and <Enter> to save the changes to the print-iommu-groups file. Make the print-iommu-groups script file executable with the following command: $ chmod +x /usr/local/bin/print-iommu-groups Now, you can run the print-iommu-groups command as follows to print the IOMMU groups of the PCI/PCIE devices installed on your Proxmox VE 8 server: $ print-iommu-groups As you can see, the IOMMU groups of the PCI/PCIE devices installed on my Proxmox VE 8 server are printed. Checking if Your NVIDIA GPU Can Be Passthrough to a Proxmox VE 8 Virtual Machine (VM) To passthrough a PCI/PCIE device to a Proxmox VE 8 virtual machine (VM), it must be in its own IOMMU group. If 2 or more PCI/PCIE devices share an IOMMU group, you can’t passthrough any of the PCI/PCIE devices of that IOMMU group to any Proxmox VE 8 virtual machines (VMs). So, if your NVIDIA GPU and its audio device are on its own IOMMU group, you can passthrough the NVIDIA GPU to any Proxmox VE 8 virtual machines (VMs). On my Proxmox VE 8 server, I am using an MSI X570 ACE motherboard paired with a Ryzen 3900X processor and Gigabyte RTX 4070 NVIDIA GPU. According to the IOMMU groups of my system, I can passthrough the NVIDIA RTX 4070 GPU (IOMMU Group 21), RTL8125 2.5Gbe Ethernet Controller (IOMMU Group 20), Intel I211 Gigabit Ethernet Controller (IOMMU Group 19), a USB 3.0 controller (IOMMU Group 24), and the Onboard HD Audio Controller (IOMMU Group 25). $ print-iommu-groups As the main focus of this article is configuring Proxmox VE 8 for passing through the NVIDIA GPU to Proxmox VE 8 virtual machines, the NVIDIA GPU and its Audio device must be in its own IOMMU group. Checking for the Kernel Modules to Blacklist for PCI/PCIE Passthrough on Proxmox VE 8 To passthrough a PCI/PCIE device on a Proxmox VE 8 virtual machine (VM), you must make sure that Proxmox VE forces it to use the VFIO kernel module instead of its original kernel module. To find out the kernel module your PCI/PCIE devices are using, you will need to know the vendor ID and device ID of these PCI/PCIE devices. You can find the vendor ID and device ID of the PCI/PCIE devices using the print-iommu-groups command. $ print-iommu-groups For example, the vendor ID and device ID of my NVIDIA RTX 4070 GPU is 10de:2786 and it’s audio device is 10de:22bc. To find the kernel module a PCI/PCIE device 10de:2786 (my NVIDIA RTX 4070 GPU) is using, run the lspci command as follows: $ lspci -v -d 10de:2786 As you can see, my NVIDIA RTX 4070 GPU is using the nvidiafb and nouveau kernel modules by default. So, they can’t be passed to a Proxmox VE 8 virtual machine (VM) at this point. The Audio device of my NVIDIA RTX 4070 GPU is using the snd_hda_intel kernel module. So, it can’t be passed on a Proxmox VE 8 virtual machine at this point either. $ lspci -v -d 10de:22bc So, to passthrough my NVIDIA RTX 4070 GPU and its audio device on a Proxmox VE 8 virtual machine (VM), I must blacklist the nvidiafb, nouveau, and snd_hda_intel kernel modules and configure my NVIDIA RTX 4070 GPU and its audio device to use the vfio-pci kernel module. Blacklisting Required Kernel Modules for PCI/PCIE Passthrough on Proxmox VE 8 To blacklist kernel modules on Proxmox VE 8, open the /etc/modprobe.d/blacklist.conf file with the nano text editor as follows: $ nano /etc/modprobe.d/blacklist.conf To blacklist the kernel modules nouveau, nvidiafb, and snd_hda_intel kernel modules (to passthrough NVIDIA GPU), add the following lines in the /etc/modprobe.d/blacklist.conf file: blacklist nouveau blacklist nvidiafb blacklist snd_hda_intel Once you’re done, press <Ctrl> + X followed by Y and <Enter> to save the /etc/modprobe.d/blacklist.conf file. Configuring Your NVIDIA GPU to Use the VFIO Kernel Module on Proxmox VE 8 To configure the PCI/PCIE device (i.e. your NVIDIA GPU) to use the VFIO kernel module, you need to know their vendor ID and device ID. In this case, the vendor ID and device ID of my NVIDIA RTX 4070 GPU and its audio device are 10de:2786 and 10de:22bc. To configure your NVIDIA GPU to use the VFIO kernel module, open the /etc/modprobe.d/vfio.conf file with the nano text editor as follows: $ nano /etc/modprobe.d/vfio.conf To configure your NVIDIA GPU and its audio device with the <vendor-id>:<device-id> 10de:2786 and 10de:22bc (let’s say) respectively to use the VFIO kernel module, add the following line to the /etc/modprobe.d/vfio.conf file. options vfio-pci ids=10de:2786,10de:22bc Once you’re done, press <Ctrl> + X followed by Y and <Enter> to save the /etc/modprobe.d/vfio.conf file. Now, update the initramfs of Proxmove VE 8 with the following command: $ update-initramfs -u -k all Once initramfs is updated, click on Reboot to restart your Proxmox VE 8 server for the changes to take effect. Once your Proxmox VE 8 server boots, you should see that your NVIDIA GPU and its audio device (10de:2786 and 10de:22bc in my case) are using the vfio-pci kernel module. Now, your NVIDIA GPU is ready to be passed to a Proxmox VE 8 virtual machine. $ lspci -v -d 10de:2786 $ lspci -v -d 10de:22bc Passthrough the NVIDIA GPU to a Proxmox VE 8 Virtual Machine (VM) Now that your NVIDIA GPU is ready for passthrough on Proxmox VE 8 virtual machines (VMs), you can passthrough your NVIDIA GPU on your desired Proxmox VE 8 virtual machine and install the NVIDIA GPU drivers depending on the operating system that you’re using on that virtual machine as usual. For detailed information on how to passthrough your NVIDIA GPU on a Proxmox VE 8 virtual machine (VM) with different operating systems installed, read one of the following articles: How to Passthrough an NVIDIA GPU to a Windows 11 Proxmox VE 8 Virtual Machine (VM) How to Passthrough an NVIDIA GPU to a Ubuntu 24.04 LTS Proxmox VE 8 Virtual Machine (VM) How to Passthrough an NVIDIA GPU to a LinuxMint 21 Proxmox VE 8 Virtual Machine (VM) How to Passthrough an NVIDIA GPU to a Debian 12 Proxmox VE 8 Virtual Machine (VM) How to Passthrough an NVIDIA GPU to an Elementary OS 8 Proxmox VE 8 Virtual Machine (VM) How to Passthrough an NVIDIA GPU to a Fedora 39+ Proxmox VE 8 Virtual Machine (VM) How to Passthrough an NVIDIA GPU on an Arch Linux Proxmox VE 8 Virtual Machine (VM) How to Passthrough an NVIDIA GPU on a Red Hat Enterprise Linux 9 (RHEL 9) Proxmox VE 8 Virtual Machine (VM) Still Having Problems with PCI/PCIE Passthrough on Proxmox VE 8 Virtual Machines (VMs)? Even after trying everything listed in this article correctly, if PCI/PCIE passthrough still does not work for you, be sure to try out some of the Proxmox VE PCI/PCIE passthrough tricks and/or workarounds that you can use to get PCI/PCIE passthrough work on your hardware. Conclusion In this article, I have shown you how to configure your Proxmox VE 8 server for PCI/PCIE passthrough so that you can passthrough PCI/PCIE devices (i.e. your NVIDIA GPU) to your Proxmox VE 8 virtual machines (VMs). I have also shown you how to find out the kernel modules that you need to blacklist and how to blacklist them for a successful passthrough of your desired PCI/PCIE devices (i.e. your NVIDIA GPU) to a Proxmox VE 8 virtual machine. Finally, I have shown you how to configure your desired PCI/PCIE devices (i.e. your NVIDIA GPU) to use the VFIO kernel modules, which is also an essential step for a successful passthrough of your desired PCI/PCIE devices (i.e. your NVIDIA GPU) to a Proxmox VE 8 virtual machine (VM).

  15. Two years after the debut of its Arc Alchemist GPUs, Intel is launching six new Arc products, but these are designed for edge/embedded systems. These edge systems, which process data near the source to reduce latency and bandwidth use, are becoming increasingly essential in areas such as IoT, autonomous vehicles, and AI applications. As Intel says, “AI at the edge is exploding with new use cases and workloads being developed daily. These AI workloads often require a high degree of parallel processing and memory bandwidth for peak performance, dedicated hardware, optimized architecture for compute efficiency, and reduced latency with faster results for real-time processing. A discrete GPU may be the ideal solution for edge AI use cases requiring high performance and complex model support.” Six SKUs The new Arc on edge GPUs are built on Intel's highly scalable Intel Xe-core architecture and support AI acceleration, visual computing and media processing. Using the OpenVINO toolkit developers can deploy AI models across Intel hardware. The Arc on edge offerings have a number of benefits, including reduced latency, improved bandwidth efficiency and better privacy and security. For high performance and to handle heavy AI workloads and expansive use cases such as facial recognition and generative conversational speech, there’s the 7XXE. For immersive visual experiences and enhanced AI inferencing capabilities, there’s the 5XXE, and for low power and small form factor requirements, Intel has the 3XXE. There are six SKUs available – the A310E and A3503 with 6 Xe-cores, the A370E and A380E with 8 cores, and the A580E and A750E with 28 cores. The A310E, A3503 and A370E have 4GB of GDDDR6 memory with 112GB/s memory bandwidth. The A380E has 6GB with 186GB/s bandwidth, while the A580E and A750E’s memory and memory bandwidth are unknown for now. Intel says only that it is “in planning”. There’s also no launch date for those two either, just TBD. The other four SKUs will be available this month. Intel Arc GPUs are built to be paired with Intel Core processors, from 10th Gen upwards and Intel Xeon W-3400 and W-2400. A number of products featuring the new Arc GPUs are set to be released in the coming months from Intel partners including from ADLINK, Advantech, Asus, Matrox and Sparkle.

  17. Nvidia’s next generation of graphics cards, reportedly known as Nvidia Blackwell, has been the subject of plenty of rumors since at least 2023. The most recent one seems to confirm that the RTX 5080 and RTX 5090 will be launching in Q4 2024, according to Twitter leaker Kopite7kimi and reported on by PC Gamer. While finally getting a hold of what could easily be the best graphics cards sounds like great news to some, finally getting a sign of the cards’ imminent release, they’re honestly coming out way too soon. There have been reports that the Nvidia RTX 5080 would have better ray tracing capabilities and pricing than the 4080 and that the RTX 5090 would be up to 70% faster than the 4090, which sounds great on paper. But when you consider how already powerful the 4000 series of cards are, it seems a bit pointless. It’s wonderful that ray tracing, speed, and performance might be improved, but to what benefit? We aren't even taking full advantage of current gen cards, so what's the value of buying a Nvidia 5000-series GPU later this year? PC games haven’t even reached the point that they truly challenge the mid-range and high-end 3000-series of graphics cards (hell, an argument can be made that they can’t fully challenge the RTX 2070 Super in ways that truly matter), let alone the current gen. One could argue that the only reason why the current gen was so necessary was thanks to the crypto mining craze completely ruining the 3000-series market and making it nigh impossible to get your hands on one for a remotely affordable price. And right now, the 4000-series is quite excellent performance-wise, as it’s able to handle ray tracing and other advanced effects and tools like no other. The RTX 4090 in particular is nearly perfect in what it can offer, and the lower cards are still absolute performance beasts. This isn’t even mentioning the Super series refreshes, which added even more oomph to your favorite graphics cards while keeping the prices either the same or lowering them. There’s also the fact that some cards, like the RTX 4070, didn’t sell nearly as well as Nvidia wanted and in fact were rumored to be a “disaster.” While that doesn’t reflect the sales numbers for the rest of the graphics cards, it’s not a good look to see the base versions of your mid-range cards doing poorly. And while the RTX 4080 Super seems to be out of stock in many retailers, that could just as well be due to low stock in the first place. With all these issues cropping up, releasing RTX 5080 and 5090 doesn’t seem to be such a smart move on Nvidia’s part. Though the Q4 2024 launch date is still just a rumor, it would be wise for the tech giant to release these cards in 2025 at the earliest to give its 4000-series some proper breathing room.
