NAME

6       pbs_gpumode - change GPU mode
7

SYNOPSIS

9       #include <pbs_error.h>
10       #include <pbs_ifl.h>
11
12       int pbs_gpumode(int connect, char *mom_node, int gpu_id, int gpu_mode)
13

DESCRIPTION

15       Issue a batch request for the pbs_mom to change the mode on one of it's
16       Nvidia GPUs.  The GPU's mode is changed by sending a GPU Control  batch
17       request to the batch server.
18
19       This call requires PBS Operator or Manager privilege.  It also requires
20       that Torque be configured with --enable-nvidia-gpu.
21
22       The argument, mom_node, specifies the host within the cluster on  which
23       the GPU is located. The argument is the name of a host that is a member
24       of the cluster of hosts managed by the server.
25
26       The argument, gpu_id, specifies ID of the GPU on the MOM node.
27
28       The argument, gpu_mode, specifies new mode of the GPU. Valid Nvidia GPU
29       modes are:
30
31              0 - Normal mode.
32
33              1 -  COMPUTE  exclusive  thread mode (only one COMPUTE thread is
34                allowed to run on the GPU).
35
36              2 - COMPUTE prohibited mode (no COMPUTE contexts are allowed  to
37                run on the GPU).
38
39              3 -  COMPUTE exclusive process mode (only one COMPUTE process is
40                allowed to run on the GPU).  This  mode  is  new  with  Nvidia
41                driver version 270.

DIAGNOSTICS

47       When the batch request generated by the pbs_gpumode() function has been
48       completed successfully by a batch server, the  routine  will  return  0
49       (zero).   Otherwise, a non zero error is returned.  The error number is
50       also set in pbs_errno.
