Charm++ parallel programming system

[Jim Edwards <jedwards AT ucar.edu>]

I was able to get it going on the cray using the gnu compilers.   I'll work with that to begin with, thanks.

Hi Jim,

Can you please e-mail us the charm builds you were using for the two machines and the errors encountered? If you use a mpi build on the AIX machine, you can avoid using charmrun and directly using mpirun/aprun/qsub or whatever launch tool is used on the machine.

For cray, the mpi-crayxt build should automatically use the cc and ftn wrappers. intel or gnu compilers work best on cray machines (and not pgi) so we recommend that people swap modules. With more detailed errors, we can probably track down the exact problems.

I can certainly have someone form our group help troubleshoot  the installation process. Just  email charm AT cs.uiuc.edu with errors encountered and someone will respond promptly.

As to the PIO library, one has to be careful since there are many ampi threads on a physical core, in general. I think "funneling" it via charm++'s groups will be a good idea. But there may be a library my student (Phil Miller) was working on that may come handy. So let us know what you are trying (email to ppl AT cs.uiuc.edu for that, rather than the charm mailing list at charm AT cs.uiuc.edu, although either will do).

Hi Prof Kale,

I have a summer intern here who was looking for a project and I thought that it would be worthwhile for him to look at performance of the PIO parallel IO library with AMPI.

We have two systems which he can run on - one is a cray xt5e, lynx, the other is an AIX pwr6 system, bluefire.    I have tried building charm++ and ampi on both systems and am running into problems.    Do you have someone there who can assist us in getting things built?  

On the AIX system charm expects loadleveler, ncar uses LSF  not  loadleveler so I need to figure out how to use charnrun with LSF.

On the cray system charm doesn't seem to know how to build using the cc and ftn compiler scripts that cray prefers.


Thanks
Jim Edwards
