Hosts in LSF are characterized by host type and host model.
The following example has a host type of X86_64. Host models are Opteron240, Opteron840, Intel_EM64T, Intel_IA64.
The combination of operating system version and host CPU architecture.
All computers that run the same operating system on the same computer architecture are of the same type — in other words, binary-compatible with each other.
Each host type usually requires a different set of LSF binary files.
