SysAdmins: to enable Accounting mode

sudo nvidia-smi -i 0 -am ENABLED

Users: to check if Accounting mode enabled or disabled

nvidia-smi -i 0 -q -d ACCOUNTING

Users: to check GPU stats per process:

nvidia-smi -i 0 --query-accounted-apps=gpu_name,pid,gpu_util,max_memory_usage,time --format=csv

Users: Accounting help

nvidia-smi --help-query-accounted-apps

FreesSurfer 6.0 with CUDA (as well as openmp). Have had issues compiling FreeSurfer with it in the recent past, no longer actively supports GPU/CUDA as Freesurfer it's permanently stuck in the past on version 5.0.35…

Request to install on ACE-GPU-1 so that we can use nvidia-docker.:

Docker: Docker >= 1.9 (official docker-engine only)
NVIDIA drivers: >= 340.29 with binary nvidia-modprobe

Why

Nvidia-Docker is officially supported by NVIDIA
Allows the containerizing of GPU applications.
Containers built using this tool should be able to be run on both ACE-GPU-1 and Guillimin.
Official github site for the project: https://github.com/NVIDIA/nvidia-docker
Requirements page for installation:https://github.com/NVIDIA/nvidia-docker/wiki/Installation

GLPI Ticket 386
For discussion at next IT Team Meeting

OpenACC directives are complementary to and interoperate with existing HPC programming models including OpenMP, MPI, and CUDA.

The directives and programming model defined in the OpenACC API document allow programmers to create high-level host+accelerator programs without the need to explicitly initialize the accelerator, manage data or program transfers between the host and accelerator, or initiate accelerator startup and shutdown.

The OpenACC Application Program Interface describes a collection of compiler directives to specify loops and regions of code in standard C, C++ and Fortran to be offloaded from a host CPU to an attached accelerator. OpenACC is designed for portability across operating systems, host CPUs, and a wide range of accelerators, including APUs, GPUs, and many-core coprocessors.
