How LIM Determines Host Models and Types
The LIM (load information manager) daemon/service automatically collects
information about hosts in an LSF cluster, and accurately determines running host
models and types. At most, 1024 model types can be manually defined in
lsf.shared.
If
lsf.shared is not fully defined with all known host models and types found in
the cluster, LIM attempts to match an unrecognized running host to one of the
models and types that is defined.
LIM supports both exact matching of host models and types, and "fuzzy" matching,
where an entered host model name or type is slightly different from what is defined
in
lsf.conf (or in ego.conf if EGO is enabled in the LSF cluster).
How does "fuzzy" matching work?
LIM reads host models and types that have been manually configured in
lsf.shared. The format for entering host models and types is
model_bogomips_architecture (for example,
x15_4604_OpterontmProcessor142,
IA64_2793, or SUNWUltra510_360_sparc). Names can be up to 64 characters long.
When LIM attempts to match running host model with what’s entered in
lsf.shared, it first attempts an exact match, then proceeds to make a fuzzy match.
