LSF Version 7.3 - Platform LSF Configuration Reference

mbschd daemon processes to specific CPUs so that higher priority daemon processes can run
more efficiently. To get best performance, CPU allocation for all four daemons should be
assigned their own CPUs. For example, on a 4 CPU SMP host, the following configuration
will give the best performance:
EGO_DAEMONS_CPUS=0 LSF_DAEMONS_CPUS=1:2 MBD_QUERY_CPUS=3
Default
Not defined

LSF_DAEMONS_CPUS in lsf.conf
MBD_REFRESH_TIME
Syntax
MBD_REFRESH_TIME=seconds [min_refresh_time]
where min_refresh_time defines the minimum time (in seconds) that the child mbatchd will
stay to handle queries. The valid range is 0 - 300.
Description
Time interval, in seconds, when mbatchd will fork a new child mbatchd to service query
requests to keep information sent back to clients updated. A child mbatchd processes query
requests creating threads.
MBD_REFRESH_TIME applies only to UNIX platforms that support thread programming.
To enable MBD_REFRESH_TIME you must specify LSB_QUERY_PORT in lsf.conf. The
child mbatchd listens 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
MBD_REFRESH_TIME has expired.
•
If MBD_REFRESH_TIME is < min_refresh_time, the child mbatchd exits at
MBD_REFRESH_TIME even if the job changes status or a new job is submitted before
MBD_REFRESH_TIME expires.
•
If MBD_REFRESH_TIME > min_refresh_time the child mbatchd exits at
min_refresh_time if a job changes status or a new job is submitted before the
min_refresh_time, or a job exits after the min_refresh_time when a job changes status or a
new job is submitted.
•
If MBD_REFRESH_TIME > min_refresh_time and no job changes status or a new job is
submitted, the child mbatchd exits at MBD_REFRESH_TIME
The value of this parameter must be between 0 and 300. Any values specified out of this range
are ignored, and the system default value is applied.
The bjobs command may not display up-to-date information if two consecutive query
commands are issued before a child mbatchd expires because child mbatchd job information
is not updated. If you use the bjobs command and do not get up-to-date information, you
may need to decrease the value of this parameter. Note, however, that the lower the value of
this parameter, the more you negatively affect performance.
The number of concurrent requests is limited by the number of concurrent threads that a
process can have. This number varies by platform:
