LSF Version 7.3 - Platform LSF Configuration Reference

•
mbatchd responds to requests by forking one child mbatchd. As soon as mbatchd has
forked a child mbatchd, the child mbatchd takes over and listens on the port to process
more query requests. For each request, the child mbatchd creates a thread to process it.
The interval used by mbatchd for forking new child mbatchds is specified by the parameter
MBD_REFRESH_TIME in lsb.params.
The child mbatchd continues to listen to the port number specified by LSB_QUERY_PORT
and creates threads to service requests until the job changes status, a new job is submitted, or
the time specified in MBD_REFRESH_TIME in lsb.params has passed (see
MBD_REFRESH_TIME in lsb.params for more details). When any of these happens, the
parent mbatchd sends a message to the child mbatchd to exit.
LSB_QUERY_PORT must be defined when NEWJOB_REFRESH=Y in lsb.params to
enable a child mbatchd to get up to date information about new jobs from the parent
mbatchd.
Operating system support
Tip:
See the Online Support area of the Platform Computing Web site
at www.platform.com for the latest information about operating
systems that support multithreaded mbatchd.
