Interval for a host to accept two jobs
The length of time in seconds to wait after dispatching a job to a host before
dispatching a second job to the same host. If the job accept interval is zero, a
host may accept more than one job in each dispatching interval. See the
JOB_ACCEPT_INTERVAL parameter in
lsb.queues and lsb.params.
RESOURCE LIMITS
The hard resource usage limits that are imposed on the jobs in the queue (see
getrlimit(2) and lsb.queues(5)). These limits are imposed on a per-job
and a per-process basis.
The possible per-job limits are:
CPULIMIT
The maximum CPU time a job can use, in minutes, relative to the CPU
factor of the named host. CPULIMIT is scaled by the CPU factor of the
execution host so that jobs are allowed more time on slower hosts.
When the job-level CPULIMIT is reached, a SIGXCPU signal is sent to all
processes belonging to the job. If the job has no signal handler for
SIGXCPU, the job is killed immediately. If the SIGXCPU signal is handled,
blocked, or ignored by the application, then after the grace period expires,
LSF sends SIGINT, SIGTERM, and SIGKILL to the job to kill it.
PROCLIMIT
The maximum number of processors allocated to a job. Jobs that request
fewer slots than the minimum PROCLIMIT or more slots than the
maximum PROCLIMIT are rejected. If the job requests minimum and
maximum job slots, the maximum slots requested cannot be less than the
minimum PROCLIMIT, and the minimum slots requested cannot be more
than the maximum PROCLIMIT.
MEMLIMIT
The maximum running set size (RSS) of a process, in KB. If a process uses
more than MEMLIMIT
kilobytes of memory, its priority is reduced so that
other processes are more likely to be paged in to available memory. This
limit is enforced by the
setrlimit system call if it supports the
RLIMIT_RSS option.
SWAPLIMIT
The swap space limit that a job may use. If SWAPLIMIT is reached, the
system sends the following signals in sequence to all processes in the job:
SIGINT, SIGTERM, and SIGKILL.
PROCESSLIMIT
The maximum number of concurrent processes allocated to a job. If
PROCESSLIMIT is reached, the system sends the following signals in
sequence to all processes belonging to the job:
SIGINT, SIGTERM, and
SIGKILL.
