Re: [ptp-user] Problem with PE proxy

The text field for advanced mode is
supposed to accept a pathname to a file that contains a list of PE environment
variable settings, for instance
MP_PROCS=2
MP_HOSTFILE=/tmp/hostfile

At the moment this is broken since the
browse button navigates to the file on the remote system but the Eclipse
code tries to find it on the local system. Please write a bugzilla bug
for this.

If you use basic mode, the PE proxy
is supposed to do what you want, where there is a field in the 'Nodes'
tab of the resources pane where you can enter the pathname of a LoadLeveler
command file. You should make sure that if you use this that any of the
other PE option settings related to node selection or resource allocation
are cleared so you don't have conflicting PE environment variable settings.
Alternatively, leave the command file field blank and use the other node
allocation parameters to specify your setup. The idea is that you set up
the run configuration as if you were invoking the poe process interactively
after setting the correct MP_* environment variables.

Unfortunately, my test system has a
problem with it's LoadLeveler setup where I can't run any LoadLeveler/PE
jobs. If what I suggest above doesn't help, then I will need to get someone
from our LoadLeveler team to help me sort this out.

Hello,
    I am attempting to use the PE proxy to run tasks remotely
on a LOP system running PE and LL. This system is setup to discourage interactive
jobs and thus appears to disallow poe invocations that specify a hostlist.
I can run poe interactively via the command line using the -llfile keyword
to specify an LL script file with a few LL commands as follows:
#@ job_type = parallel
#@ node_usage = not_shared
#@ environment = COPY_ALL
#@ tasks_per_node = 2
#@ node = 1
#@ wall_clock_limit = 0:15:00
#@ queue

The problem is I can't seem to figure out how to make this work via the
PE proxy. I have tried various setups using the basic mode as well as using
advanced mode. When I use advanced mode I have a simple file (on the remote
system) containing a single PE keyword:
MP_LLFILE=llfile

This fails as well. Here is a debug trace from the Eclipse application
that seems to indicate that it can't find the script file. However, the
path specified is correct so I am not sure why it can't locate the file.
Alternatively is there an "advanced" mode that simple uses a
LL script file? By the way, I need to run interactively for other reasons
so I don't think the LL proxy will work for my situation.
