Depending upon what version you are using, this could be resolved fairly
simply. Check to see if your version supports the "nooversubscribe" command
line option. If it does, then setting that option may (I believe) resolve
the problem - at the least, it will only allow you to run one application

I can't speak to the Perl bindings, but Open MPI's runtime already supports
SGE, so all you have to do is "mpirun" like usual and we take care of the
rest. You may have to check your version of Open MPI as this capability was
added in the more recent releases.

Could you confirm the version you are using? I think there is a typo there.
Also, could you tell us how you configured the code (the configure command

Hi Lydia
Thanks - that does help!
Could you try this without threads? We have tried to make the system work
with threads, but our testing has been limited. First thing I would try is
to make sure that we aren't hitting a thread-lock.
Thanks

Easiest method is just to use the "mpicc" command to compile your code. It
will automatically link you to the right libraries, include directories,
etc. You can check the $prefix/bin directory to see all the compiler
wrappers we provide.

If you wouldn't mind, could you try it again after applying the attached

On 1.1.2, what that error is telling you is that it didn't find any nodes in

Just out of curiosity what environment (i.e., allocator and launcher) are
you running in? POE?
I¹m not sure the POE support is all that good, which is why I ask.

Actually, I believe at least some of this may be a bug on our part. We
currently pickup the local environment and forward it on to the remote nodes
as the environment for use by the backend processes. I have seen quite a few
environment variables in that list, including DISPLAY, which would create

Hi Lydia
I would like to say we clean up perfectly, but :-(
The system does try its best. I'm a little surprised here since we usually
clean up when an application process fails. Our only known problems are when
one or more of the orteds fail, usually due to a node rebooting or failing.

I would suggest using the nightly snapshot off of the trunk - the poe module
compiles correctly there. I suspect we need an update to bring that fix over
to the 1.2 branch.

Hi Eddie
Open MPI needs to create a temporary file system what we call our ³session

output, it appears that your /tmp directory is ³locked² to root access only.

Oh, I should have made something clear - I believe those command line

Now that's interesting! There shouldn't be a limit, but to be honest, I've
never tested that mode of operation - let me look into it and see. It sounds
like there is some counter that is overflowing, but I'll look.

I can't speak to the MPI problems mentioned in here as my area of focus is
solely on the RTE. With that caveat, I can say that - despite the fact there
is little thread safety testing in the system - I haven't heard of any
trouble launching non-MPI apps. We do it regularly, in both threaded and
non
resulting output so we can figure out
what is going on.

It isn't a /dev issue. The problem is likely that the system lacks
sufficient permissions to either:
1. create the Open MPI session directory tree. We create a hierarchy of
subdirectories for temporary storage used for things like your shared memory

I can't really test this solution as the Torque dynamic host allocator

the released code). However, the attached code should cleanly add any nodes
to any existing allocation known to OpenRTE.
