Description

PMT (pmt.rb) currently supports an "addExecutable" function via XMLRPC. This function hasn't been tested or used much so far, but in the medium term, we would like the ability to reconfigure the MPI program layout that PMT manages by sending XMLRPC messages to PMT. This could correspond to adding a removeExecutable(exeIdentifier) function, adding a reconfigure option, or both.

At the moment, the following two scenarios are supported by PMT:

start PMT with a list of desired applications, hostnames, and ports (this automatically starts the MPI program)
send the stopSystem command to PMT
optionally add new executables to the list managed by PMT (but this has never been done, so far)
send the startSystem command to PMT
send more stopSystem and startSystem commands

start PMT
send it addExecutable commands via XMLRPC to define the MPI program layout that is desired
send the startSystem command to PMT
send the stopSystem command to PMT
optionally add new executables to the list managed by PMT (but this has never been done, so far)
send the startSystem command to PMT
send more stopSystem and startSystem commands
