IBM® Spectrum LSF 10.1 Fix 555171 Readme File
Abstract
P103804. Fix to ensure that the Docker image information can be transferred successfully and enhancement to enable Docker image affinity.
Description
Readme documentation for IBM® Spectrum LSF 10.1 Fix 555171 including installation-related instructions, prerequisites and co-requisites, and list of fixes.
This fix addresses the following issue:
1. Change LSF to use the TCP protocol for the Docker image information transformation between the master LIM and the mbatchd daemon, and between the slave LIM and master LIM, to avoid failure when using the UDP protocol if the message size is large.
2. Introduce a new parameter "LSF_DOCKER_IMAGE_UPDATE_INTERVAL" to the lsf.conf file to enable the Docker image affinity feature. The following is a description of this parameter:
Syntax
LSF_DOCKER_IMAGE_UPDATE_INTERVAL= 0 | time_in_seconds
Description
- If LSF_DOCKER_IMAGE_UPDATE_INTERVAL is not defined or is set to 0, Docker image affinity related functions are disabled. In this case, the LSB_DOCKER_IMAGE_AFFINITY environment variable in the job submission environment and the DOCKER_IMAGE_AFFINITY parameter value in the lsb.applications, lsb.queues, and lsb.params files are ignored.
- If LSF_DOCKER_IMAGE_UPDATE_INTERVAL is set to a positive integer, users can enable Docker image affinity features at the job, application, queue, or cluster level by setting the LSB_DOCKER_IMAGE_AFFINITY environment variable in the job submission environment or setting the DOCKER_IMAGE_AFFINITY parameter in the lsb.applications, lsb.queues, or lsb.params file. The defined value determines the interval of the mbatchd daemon getting the Docker image affinity information from the master LIM, and the interval of the slave LIMs checking whether the Docker image information changes and whether this information needs to be sent to the master LIM.
Default
0. Docker image affinity feature is disabled.
