LSF Version 7.3 - Using Platform LSF HPC

About Platform LSF and MPICH-P4
MPICH is a freely available, portable implementation of the MPI Standard for message-
passing libraries, developed jointly with Mississippi State University. MPICH is designed
to provide high performance, portability, and a convenient programming environment.
MPICH-P4 is an MPICH implementation for the ch_p4 device, which supports SMP
nodes, MPMD programs, and heterogeneous collections of systems.
Requirements
❏ MPICH version 1.2.5 or later
You should upgrade all your hosts to the same version of MPICH-P4.
Assumptions and limitations
◆ MPICH-P4 is installed and configured correctly
◆ The user's current working directory is part of a shared file system reachable by all
hosts
◆ The directory specified by the MPICH_HOME variable is accessible by the same
path on all hosts
◆ Process group files are not supported. The mpich.ch_p4 p4pg option is
ignored.
Glossary
(Message Passing Interface) A message passing standard. It defines a message passing
API useful for parallel and distributed applications.
A portable implementation of the MPI standard.
An MPI implementation based on MPICH for the chp4 device.
(Parallel Application Manager) The supervisor of any parallel job.
(Parallel Job Launcher) Any executable script or binary capable of starting parallel tasks
on all hosts assigned for a parallel job.
(Remote Execution Server) An LSF daemon residing on each host. It monitors and
manages all LSF tasks on the host.
(TaskStarter) An executable responsible for starting a task on the local host and
reporting the process ID and host name to the PAM.
