Specifications
The P8 Test System consists of two IBM Power 822LC Servers each with 2x8core 3.25GHz Power8 CPUs and 512GB Ram. Similar to Power 7, the Power 8 utilizes Simultaneous MultiThreading (SMT), but extends the design to 8 threads per core allowing the 16 physical cores to support up to 128 threads. Each node has two NVIDIA Tesla K80 GPUs with CUDA Capability 3.7 (Kepler), consisting of 2xGK210 GPUs each with 12 GB of RAM, so each node has effectively 4 GPU's.
Compile/Devel/Test
First login via ssh with your scinet account at login.scinet.utoronto.ca, and from there you can proceed to p8t01 and p8t02.
Software
GNU Compilers
gcc version 4.8.5 is the default with RHEL 7.2. To load the newer advance toolchain version use:
module load gcc/5.3.1
IBM Compilers
IBM compilers xlc/xlc++ 13.1.4 and xlf 15.1.4 are available by default
NVIDIA toolkit
Driver Version
The current NVIDIA driver version for gravity is 352.93
CUDA
The current installed CUDA Tookit is 7.5.
module load cuda/7.5
The CUDA driver is installed locally, however the CUDA Toolkit is installed in:
/usr/local/cuda-7.5/
OpenMPI
Currently OpenMPI has been setup on the two nodes connected over FDR Infiniband.
$ module openmpi/1.10.3-gcc-4.8.5
