HP-MPI Version 2.0 for Windows Release Note

for saving the job as a job description file. You must submit

the configuring job to begin execution.

-hpcunit node

[core|socket|node]

Specifies the unit of entities that can be scheduled as

defined by the HPC scheduler. The defaults is core.

NOTE: -hpcunit node is the replacement for -nodex.

The difference is -nodex requires -np x to include all

cores for the nodes. -hpcunit node -np y, y

accurately reflects a single rank on y nodes. The -nodex

option is deprecated.

-hpcjobtemplate

Applies the job template to the scheduled job.

-hpcnodegroups

<nodegroup(s)>

Schedules the job to a specific node group as defined by

the HPC cluster. The parameter takes one or more node

groups, specified by a comma separated list.

-hpcpriority

[Lowest|BelowNormal|Normal|,

AboveNormal|Highest]

Specifies the HPC job priority.

2.14 New HPC Environment Variables

MPI_SAVE_TASK_OUTPUT Saves the output of the scheduled HPCCPService task to

a file unique for each node. This option is useful for

debugging startup issues. This option is not set by default.

MPI_FAIL_ON_TASK_FAILURE

Sets the scheduled job to fail if any task fails. The job will

stop execution and report as failed if a task fails. The

default is set to true (1). To turn off, set to 0.

MPI_COPY_LIBHPC Controls when mpirun copies libhpc.dll to the first

node of HPC job allocation. Values:

• 0 – Don't copy.

• 1 (default) – Use cached libhpc on compute node.

• 2 – Copy and overwrite cached version on compute

nodes.

For more information, see “MPI_COPY_LIBHPC” (page 51).

2.15 Support for Non-HPC Flags

-pwcheck

Validates the cached user password by obtaining a login

token locally and verifying the password. A pass/fail

message is returned before exiting.

To check password and authentication on remote nodes,

use the -at flag with mpidiag.
