ARCHITECTURE
(Reserved for system use only) Indicates automatically detected host models that correspond
to the model names.
CPUFACTOR
Though it is not required, you would typically assign a CPU factor of 1.0 to the slowest machine
model in your system and higher numbers for the others. For example, for a machine model
that executes at twice the speed of your slowest model, a factor of 2.0 should be assigned.
MODELNAME
Generally, you need to identify the distinct host types in your system, such as MIPS and SPARC
first, and then the machine models within each, such as SparcIPC, Sparc1, Sparc2, and Sparc10.
About automatically detected host models and types
When you first install LSF, you do not necessarily need to assign models and types to hosts in
lsf.cluster.cluster_name. If you do not assign models and types to hosts in
lsf.cluster.cluster_name, LIM automatically detects the model and type for the host.
If you have versions earlier than LSF 4.0, you may have host models and types already assigned
to hosts. You can take advantage of automatic detection of host model and type also.
Automatic detection of host model and type is useful because you no longer need to make
changes in the configuration files when you upgrade the operating system or hardware of a
host and reconfigure the cluster. LSF will automatically detect the change.
Mapping to CPU factors
Automatically detected models are mapped to the short model names in lsf.shared in the
ARCHITECTURE column. Model strings in the ARCHITECTURE column are only used for
mapping to the short model names.
Example lsf.shared file:
Begin HostModel
MODELNAME CPUFACTOR ARCHITECTURE
SparcU5 5.0 (SUNWUltra510_270_sparcv9)
PC486 2.0 (i486_33 i486_66)
PowerPC 3.0 (PowerPC12 PowerPC16 PowerPC31)
End HostModel
If an automatically detected host model cannot be matched with the short model name, it is
matched to the best partial match and a warning message is generated.
If a host model cannot be detected or is not supported, it is assigned the DEFAULT model
name and an error message is generated.
For Solaris machines, the keyword int is reserved and cannot be used
