Spectrum LSF 10.1 Fix 601821
Abstract
P105008. When
ALLOCATION_PLANNER is enabled in lsb.params, this
patch addresses the following problems: 1) Allocation plans are cancelled
unexpectedly for jobs that request memory in their rusage
strings; and, 2) LSF does not reserve sufficient resources to ensure that an
allocation plan is carried out.
Description
Readme documentation
for IBM Spectrum LSF 10.1 Fix 601821, including installation-related
instructions, prerequisites and co-requisites, and list of fixes.
This fix addresses
the following issues with plan-based allocation, which is enabled using the parameter ALLOCATION_PLANNER
in lsb.params:
1. For jobs that specify memory in their rusage strings, allocation plans can be cancelled
unexpectedly in certain cases. The result is that these jobs are delayed from
dispatching.
2. Once LSF creates an allocation plan, it must
reserve sufficient resources to ensure that the plan is carried out. In some cases, LSF will not reserve
sufficient resources. As a result, jobs without allocation plans are able to
dispatch on resources needed for planned jobs, and
delaying dispatch of the planned jobs. This fix ensures that sufficient
resources are reserved for planned jobs.

5. Installation and
configuration
Before you
install
LSF_TOP is the full path to the top-level installation directory of LSF.
1.
Before you apply this fix,
ensure that you installed LSF 10.1 Fix Pack 12 or later.
2.
Starting in LSF 10.1 Fix Pack 13, the default values of the following
three GPU parameters are changed to:
LSF_GPU_AUTOCONFIG=Y
LSB_GPU_NEW_SYNTAX=extend
LSF_GPU_RESOURCE_IGNORE=Y
If you have Fix Pack 13 installed, these GPU parameters not configured in the lsf.conf configuration file will take the default
values, and the parameters already configured in the lsf.conf
file will not be affected.
If you want to keep the former GPU behavior, and if any of the three parameters
are missing in the lsf.conf
configuration file, you must explicitly configure the following default
settings that are defined in Fix Pack 12 or earlier:
LSF_GPU_AUTOCONFIG=N
LSB_GPU_NEW_SYNTAX=N
LSF_GPU_RESOURCE_IGNORE=N
