Define computation of ncpus on static hosts

About this task

The ncpus global definition can be overridden on specified dynamic and static hosts in the cluster.

Procedure

Open lsf.cluster.cluster_name.
- Linux: LSF_CONFDIR/lsf.cluster.cluster_name
- Windows: LSF_CONFDIR\lsf.cluster.cluster_name
Find the host you for which you want to define ncpus computation. In the RESOURCES column, add one of the following definitions:
- define_ncpus_procs
- define_ncpus_cores
- define_ncpus_threads
Note:
Resource definitions are mutually exclusive. Choose only one resource definition per host.

For example:
```
Begin Host
HOSTNAME  model    type        r1m  mem  swp  RESOURCES    #Keywords
#lemon    PC200    LINUX86     3.5  1    2   (linux)
#plum     !        NTX86       3.5  1    2   (nt)
Host_name !        NTX86        -   -    -   (define_ncpus_procs)
End     Host
```
Save and close lsf.cluster.cluster_name.
Restart the master host.

Results

Note:

In multi-cluster environments, if ncpus is defined on a per-host basis (thereby overriding the global setting) the definition is applied to all clusters that the host is a part of. In contrast, globally defined ncpus settings only take effect within the cluster for which EGO_DEFINE_NCPUS is defined.
