HPC Village

HPC Village from Openwall is an opportunity for HPC (High Performance Computing) hobbyists alike to program for a heterogeneous (hybrid) HPC platform. Participants are provided with remote access (via the SSH protocol) to a server with multi-core CPUs and HPC accelerator cards of different kinds - Intel MIC (Xeon Phi), AMD GPU, NVIDIA GPU - as well as with pre-installed and configured drivers and development tools (SDKs).

We provide within one machine access to the mentioned four types of computing devices, including OpenCL support for all of them, as well as support for development tools and usage models specific to some of them (OpenMP on CPU, OpenMP offload from CPU to MIC, CUDA on NVIDIA GPU). Although it is uncommon to use more than two types of computing devices within one node in real-world HPC setups, such configuration is convenient for getting acquainted with the different technologies, for trying out and comparing them on specific tasks, and for development of portable software programs (including debugging and optimization).

Hardware

The current hardware configuration is as follows:

  • Supermicro GPU SuperWorkstation 7047GR-TPRF workstation/server platform with MCP-290-00059-0B rackmount rail set
    • 4U chassis
    • Two 1620W PSUs (normally both are active and are sharing the load)
    • Dual socket 2011 motherboard with IPMI, 16 memory sockets, four PCIe 3.0 x16 slots for full-length dual-width PCIe cards and a fifth slot for a shorter card
    • A full set of cooling fans, including those pulling hot air out of passively-cooled accelerator cards
  • Two 8-core Intel Xeon E5-2670 CPUs
    • Sandy Bridge-EP, support AVX and AES-NI
    • A total of 16 CPU cores seen as 32 logical CPUs (two hardware threads per core), at a clock rate of at least 2.6 GHz
    • Turbo boost to up to 3.0 GHz with all cores in use or 3.3 GHz with few cores in use
  • 128 GB DDR3-1600 ECC RAM
    • 8x 16 GB DDR3-1600 ECC Registered modules on 8 channels (4 channels per CPU)
    • Theoretical bandwidth 102.4 GB/s, actual measured bandwidth ~85 GB/s (cumulative from 32 threads)
  • Intel Xeon Phi 5110P coprocessor module
    • Intel Many Integrated Core (MIC) architecture, Knights Corner
    • 60 cores (x86-ish with 512-bit SIMD units) seen as 240 logical CPUs (four hardware threads per core), 1053 MHz, 8 GB GDDR5 ECC RAM on a 512-bit bus, 320 GB/s
    • Peak performance of about 2 TFLOPS single-precision, 1 TFLOPS double-precision
  • NVIDIA GTX 1080 gaming graphics card (short form factor, manufactured by Gigabyte)
    • NVIDIA Pascal architecture
    • One GP104 GPU with 2560 SPs at 1607 MHz to 1771 MHz, 8 GB GDDR5X RAM on a 256-bit bus, 320 GB/s
    • Peak performance of over 8 TFLOPS single-precision
  • NVIDIA GTX Titan X gaming graphics card (reference design, manufactured by Gigabyte)
    • NVIDIA Maxwell architecture
    • One GM200 GPU with 3072 SPs at 1000 MHz to 1076 MHz, 12 GB GDDR5 RAM on a 384-bit bus, 336 GB/s
    • Peak performance of over 6 TFLOPS single-precision
  • NVIDIA GTX TITAN gaming graphics card (Zotac GeForce GTX TITAN AMP! Edition)
    • NVIDIA Kepler architecture
    • One GK110 GPU with 2688 SPs at 902 MHz to 954 MHz in single-precision mode, 6 GB GDDR5 RAM on a 384-bit bus, 317.2 GB/s
    • Peak performance of over 5 TFLOPS single-precision, from 1.3 to 1.5 TFLOPS double-precision in the corresponding mode
    • This is a budget replacement for the TESLA K20X GPU card intended for workstations and servers (which would cost at least 3 times more and would run considerably slower at single-precision and integer code, but would offer ECC RAM)
  • AMD Radeon RX Vega 64 gaming graphics card (reference design, manufactured by MSI with slight overclocking)
    • AMD GCN 5th gen architecture
    • One Vega10 XT GPU with 4096 SPs at 1272 to 1575 MHz, 8 GB HBM2 RAM on a “2048-bit” bus, 483.8 GB/s
    • Peak performance of over 10 TFLOPS single-precision

Total peak performance is over 31 TFLOPS single-precision.

Software

The operating system is Scientific Linux 6.10 (with several devtoolsets installed, such as providing a variety of newer GCC versions), since this is a common free option to run Intel MPSS as needed to access the Xeon Phi card (which, in turn, runs its own copy of Linux, coming from Intel MPSS). We also have CUDA 10.0 with its driver version 410.79, and AMD AMDGPU-PRO 18.50.

Here's what this looks like via OpenCL:

In the organizers' sole discretion, access may be denied or restricted (in particular, in case it is used for other than an intended purpose or/and if one's use of the system inconveniences other users in a substantial way). The information contained in this announcement does not formally constitute an offer to provide any service to the general public.
