Charm++ parallel programming system

[Abhinav S Bhatele <bhatele AT illinois.edu>]

Hello Jeff,

Can you tell us which version of Charm are you using?

I recently made some changes to the development branch which should fix some problems.

I know that some people at Cray have been running the mpi-crayxt build on the XE6. So, it should work (with some changes to conv-mach.sh as you point out).

Hello Charm-ers, 

Do you have any advice on how to configure Charm++ to build for a Cray XE6 target?  

I "successfully" built Charm++ using the pre-defined "mpi-crayxt" arch on the XE6.  Then, I attempted to test it with the included "megatest", but a simple 4-proc job fails (with no useful error messages).  We have been able to build Charm++ for our XT5 without problems using the "mpi-crayxt" arch.

The main differences between the XT5 and XE6 are the interconnect and processors.  If you are interested, see this short blurb for some basic info about the system:  http://www.cscs.ch/489.0.html?&tx_ttnews[tt_news]=29&tx_ttnews[backPid]=488&cHash=31ce85ee7b

Which files and parameters should I focus on changing?  I'm assuming that I should copy the arch/mpi-crayxt directory and probably modify the "conv-mach" files, but any insight that you can provide will be very helpful.  I'll be happy to test it and report back the results.

Best regards, 

Jeff
