Specifying shared resources with the keyword “defined”
A shared resource may be used in the resource requirement string of any LSF
command. For example, when submitting an LSF job that requires a certain amount
of shared scratch space, you might submit the job as follows:
bsub -R "avail_scratch > 200 && swap > 50" myjob
The above assumes that all hosts in the cluster have access to the shared scratch
space. The job is only scheduled if the value of the
"avail_scratch" resource is
more than 200 MB and goes to a host with at least 50 MB of available swap space.
It is possible for a system to be configured so that only some hosts within the LSF
cluster have access to the scratch space. To exclude hosts that cannot access a shared
resource, the
defined(resource_name) function must be specified in the resource
requirement string.
For example:
bsub -R "defined(avail_scratch) && avail_scratch > 100 && swap > 100"
myjob
would exclude any hosts that cannot access the scratch resource. The LSF
administrator configures which hosts do and do not have access to a particular
shared resource.
Supported resource
names in the
defined function
Only the following resource names are accepted as the argument in the
defined(resource_name) function:
◆ The following builtin resource names:
LSF_Base lsf_base LSF_Manager lsf_manager LSF_JobScheduler
lsf_js LSF_Make LSF_parallel LSF_Analyzer lsf_analyzer
◆ Resource names configured inlsf.shared, except dynamic NUMERIC
resource names with INTERVAL fields defined.
The following resource names are not accepted in the
defined(resource_name)
function:
◆ The following builtin resource names:
r15s r1m r15m ut pg io ls it tmp swp mem ncpus ndisks maxmem
maxswp maxtmp cpuf type model status rexpri server and hname
◆ Dynamic NUMERIC resource names configured inlsf.shared with
INTERVAL fields defined. In the default configuration, these are
mode, cntrl,
it_t.)
◆ Other non-builtin resource names not configured lsf.shared.
a && b Logical AND: 1 if both a and b are non-zero, 0 otherwise
