Step 1: Configuring the Grub Assuming you are using an Intel CPU, either SSH directly into your Proxmox server, or utilizing the noVNC Shell terminal under "Node", open up the /etc/default/grub file. I prefer to use nano, but you can use whatever text editor you prefer. nano /etc/default/grub Look for this line: GRUB_CMDLINE_LINUX_DEFAULT="quiet" Then change it to look like this: For intel GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on" For AMD GRUB_CMDLINE_LINUX_DEFAULT="quiet amd_iommu=on" When you finished editing /etc/default/grub run this command: update-grub Step 2: VFIO Modules You'll need to add a few VFIO modules to your Proxmox system. Again, using nano (or whatever), edit the file /etc/modules nano /etc/modules Add the following (copy/paste) to the /etc/modules file: vfio vfio_iommu_type1 vfio_pci vfio_virqfd Then save and exit. Step 3: IOMMU interrupt remapping I'm not going to get too much into this; all you really need to do is run the following commands in your Shell: echo "options vfio_iommu_type1 allow_unsafe_interrupts=1" > /etc/modprobe.d/iommu_unsafe_interrupts.conf echo "options kvm ignore_msrs=1" > /etc/modprobe.d/kvm.conf Step 4: Adding Phi to VFIO Run this command: lspci -v Your shell window should output a bunch of stuff. Look for the line(s) that show your Phi. It'll look something like this: 42:00.0 Co-processor: Intel Corporation Xeon Phi coprocessor 5100 series (rev 11) Subsystem: Intel Corporation Xeon Phi coprocessor 5100 series Flags: bus master, fast devsel, latency 0, IRQ 15, NUMA node 1 Memory at 3be00000000 (64-bit, prefetchable) [size=8G] Memory at d40e0000 (64-bit, non-prefetchable) [size=128K] Capabilities: [44] Power Management version 3 Capabilities: [4c] Express Endpoint, MSI 00 Capabilities: [88] MSI: Enable- Count=1/16 Maskable- 64bit+ Capabilities: [98] MSI-X: Enable- Count=16 Masked- Capabilities: [100] Advanced Error Reporting Kernel driver in use: vfio-pci Kernel modules: mic_host Run the command below. Replace 42:00.0 with whatever number was next to your Phi when you ran the previous command: lspci -n -s 42:00.0 The output should look lithe this: 42:00.0 0b40: 8086:2250 (rev 11) What we want to keep, are these vendor id codes: 8086:2250 Now we add the Phi vendor ids to the VFIO (remember to replace the id's with your own!): echo "options vfio-pci ids=8086:2250 disable_vga=1"> /etc/modprobe.d/vfio.conf Finally, we run this command to update the configs and reboot: update-initramfs -u reboot Step 5: Verify Configuration To check if your changes were successful, you can use: lspci -nnk and check your device entry. It should look like: 42:00.0 Co-processor [0b40]: Intel Corporation Xeon Phi coprocessor 5100 series [8086:2250] (rev 11) Subsystem: Intel Corporation Xeon Phi coprocessor 5100 series [8086:2500] Kernel driver in use: vfio-pci Kernel modules: mic_host The important line of that is: Kernel driver in use: vfio-pci If it looks looks that, or the in use line is missing entirely, the device is ready to be used for pass-through. Step 6: Create the VM Making a Virtual Machine is pretty easy and self-explanatory, but if you are having issues, I suggest looking up the official Proxmox Wiki and How-To guides. go through the process and set the hardware to what you think is reasonable for your environment. Step 7: Edit the VM Config File Going back to the Shell window, we need to edit /etc/pve/qemu-server/<vmid>.conf, where <vmid> is the VM ID Number you used during the VM creation (General Tab). nano /etc/pve/qemu-server/<vmid>.conf In the editor, let's add these command lines (doesn't matter where you add them, so long as they are on new lines. Proxmox will move things around for you after you save): machine: q35 cpu: host,hidden=1,flags=+pcid args: -cpu 'host,+kvm_pv_unhalt,+kvm_pv_eoi,hv_vendor_id=NV43FIX,kvm=off' Save and exit the editor. Step 8: Add PCI Devices (Your Phi) to VM To pass through the device you need to set the hostpciX option in the VM configuration, for example by executing: qm set VMID -hostpci0 42:00.0 Step 9: Start and Configure your VM power on the Vm. the Phi will be connected. Thank you for coming to my TED talk! I realize this is about 8 years late, but I spent about 10 hours figuring this out this week. The Phi is different to pass-through than a GPU and I hope this is helpful.

I don't know any in-depth details about how Xeon Phi's work but my basic understanding is that they behave like normal CPUs that you can add via PCIe add-in cards. Today I wondered about two things: If you bought a mining motherboard (you know, one of those that has like 20 PCIe slots), and enough Xeon Phi cards to completely populate it, would it work at all? And if it did work, and you ran some synthetic CPU benchmarks and productivity workloads on it (I would expect gaming to completely suck), how would it compare to just a single 64-core Threadripper? Or if anyone wants to chip in w/ an explanation of just how those cards worked in general, that would be pretty cool to know as well.

server board How Boot A Singal Node Compuer?
Visirs posted a topic in CPUs, Motherboards, and Memory
Hi,linus and other netfriends, Im a fan of LTT for a long time,now I have joined the LTT forums ,finally! May two months ago ,I got a HNS7200AP Compute Node But now,I have many problems on this compute node. FIRST: The motherboard used a power docking board from PSU to catch the power,with a 16pin Molex adapter,input 12V voltage to the motherboard. This is the PSU controler chip. SECOND: After I checked the define of power docking board,I found that it have no any 12V standby input and no any PSU control signal input.However,the fan controler adapter have a PSU-OK signal output!It's really strange!Becaues the PSU-OK signal should output from the PSU itself!Also,the PSU only output the 12V stby,well,ok,but from the define tabel,the motherboard seems only allowed 3.3Vstby and 5Vstby input only.How?Why? So,I guess it must had some other connect from PSU to the board.I found the FrontPanel connecter to the board,Intel called it Bridge Board.Wow,there are many normally adapter like 4xSATA(from SAS),power LED,HDD LED,IPMB,5V AUX,even USB2.0 and more.The most important: the PMBus --- PSU controler. The bridge board's pin define as: Here are another photos: 1.The define of fan controler adapter: 2.Intel CRPS PSU output define: 3.A real CRPS PSU photo of mine. 4.The only I have,is a single node like this: Now,dear of my friends: How I boot the computer rightly if I had these problems following? 1.I have no the chassis called H2000G,but the front panel on it. 2.I still can not understand how 12V stby becomes 5Vstby and 3.3V's,by some kind of DC-DC transformer? 3.I can connect the PSU with Power docking board ,it just need some wires,but which other pins must I connected them? Thanks for your reading and reply(hope you can!),no matter it helps me or not!- 2 replies

Some days ago, I ask Linus to borrow his Larrabee GPU. Now I got some news. I test 4 hours, and made Larrabee can work. Although it just show 'Microsoft display adapter' in the Windows(Because I also doesn't have drive) . But, other player's Larrabee just shows 'Unkonw device' in the Windows System. But this Larrabee can show 'Microsoft display adapter', it can be recognized as a graphics card in the Windows System!! This Larrabee may be the only other player in the world that can be recognized as a graphics card. (By the way, it is work ,but its buzzer will always sound, like '—.—' one long one short one long. [My test motherboard:Gigabyte-Z78X-UD5H(But you also need put HDMI or DP in motherboard, Larrabee can't used alone like P106 GPU)] Bilibili:结城安穗(YuuKi-AnS) Bilibili Link:https://space.bilibili.com/66644159

watching the latest video about the xeon phi got me wondering how would the xeon phi fare doing x264 encoding for a professional stream encoder?
-
just built a new computer, and found out terragen does not use gpu, instead, it used CPU and al ost eveytime, they cpu thermal throttles and i thought i could use xeon phi, so would it work with Z390? it said it would work with motherboard above 4G decoding, what does that mean

Hey guys, did you seen this fake GPU(xe)? Some days ago, I get a Xeon Phi Co-processor on XianYu (Like ebay), when I get it and open its cover, I was so surprised, here are its pictures. (I know Xeon Phi is not GPU) Its core is same as Intel Xeon Phi x200 family CPU. But its BGA. This Xeon Phi has a PLX:PEX8733 and intel chipset C612J. It has a MicroUSB to test. I don't know why, intel often make some so strange EngineeringSample like this.

for some time i have had an Intel xeon phi 3120P engineering sample in my possession and feeling terrible not being able to use it. my father bought it for an unknown reason, possibly thinking it would work well with our dual w5590 1u system. after many attempts and no success my father gave up on trying to get it to work. i am well aware of the purpose co-processors have but i have idea's for it that i wish to try. 1. adobe video rendering. with 228 threads of power who could resist trying to render video's and tremendously reduce render times but keep every bit of quality? 2. blender rendering while i currently am still learning how to use blender i would like to know that whenever i have a project ready to render that i have a small render farm at my disposal. 3. folding@home while i'm quite sure this would probably never work it would be interesting to see if it could be made to work. dramatically reducing the time it takes to complete each fold. while i know that what i am asking here is strange, i would very much like to know if any of the 3 things i wish to do with it can be done and if it is i will try my very best to make that happen. any helpful comments are greatly appreciated.

At ISC 2016, Intel has announced their newest KNL (Knight's Landing) Xeon Phi processors has started to ship. KNL Xeon Phi, will actually be a host processor (socket) or co-processor (PCIe), not like their older Xeon Phi products where it's only a co-processor. What that means is, the host based version, can actually be used as a stand alone CPU. There are 2 kinds, one with Omni-Path, which provides insane network bandwidth, and the other without. Currently there are 4 SKUs 7210, 7230, 7250, and 7290. 64 cores running at 1.3GHz are for the bottom 2, and other 4 cores and +100MHz are added for the 7250. A additional 4 more cores with another +100MHz, topping out at 72 cores running at 1.5GHz for the 7290. Each CPU has 16GB of onboard MCDRAM, using Micron HBM memory, providing more than 400GB/s of bandwidth, except for 7120, which may run slower, since its HBM transfer rate is capped at 6.4GT/s compare to 7.2GT/s on the other 3 SKUs. On the standard memory side, they runs on 6 channel DDR4 @ 2400MHz and up to 384GB max. The 7210 is clocked slower at DDR4 2133MHz. 36 PCIe 3.0 lanes are provided by the CPU with additional 4 from the Wellsburg PCH. For the Omni-Path fabric, All of them are built on the 14nm processor using the Silvermont architecture, which is what Intel uses to built their Atom based cpu running on mobile phones and tablets. TDP ranges from 215w to 245w for the 7290. Omni-Path version adds a additional +15w to the total TDP, so a 7290 with Omni-Path will have a TDP of 260w. It uses LGA3467 and price starts out at $2,438 for the entry level 7120 and up to $6,254 for top of the line 7290. Product Name: Intel Xeon Phi Code Name: Knights Landing Cores: 64-72 Speed: 1.3GHz - 1.5GHz Turbo: 1.5GHz - 1.7GHz Cache: 32MB L2 MCDRAM: 16GB Micron HBM Intel Xeon Phi with Omni-Path fabric http://www.intel.com/content/www/us/en/processors/xeon/xeon-phi-detail.html http://ark.intel.com/products/family/92650/Intel-Xeon-Phi-Product-Family-x200#@Server http://www.tomshardware.com/news/intel-xeon-phi-knights-landing,32121.html

I was using Ubuntu the other day, configured it for SLI, and got this problem: So this got me thinking, could Intel Xeon Phi coprocessors, seen here: http://www.intel.com/content/www/us/en/processors/xeon/xeon-phi-detail.html Act as substitutes for high-end graphics cards or multi-GPU setups? Because, as of right now, support for high-end graphics setups on Linux systems seems pretty dismal.

Will a coprocessor help at all for a task other than server hosting? Is there a way to run x11,physX, or open GL on it? Can I see some benchmarks with a coprocessor if it helps?

Now that's some cool looking chip. Maybe Skylake-E will look something like this too. lol http://www.anandtech.com/show/9802/supercomputing-15-intels-knights-landing-xeon-phi-silicon-on-display
