Charm++ parallel programming system

[Abhinav Bhatele <bhatele AT illinoisalumni.org>]

It should work with most mpi installs as long as the include and lib files are in the usual places. If you have mpicc and mpicxx pointing to the intel compilers you can add that to the build like this:

./build charm++ mpi-linux-x86_64 mpicxx --with-production

Hello Abhinav,

Thank you for the quick reply.  What flavor of mpi libraries do the builds below assume is being used?
We have mpi wrappers for intel compilers that might need to be inserted with the first two builds.

Hi Brian,

You can try a couple different charm builds and then benchmark NAMD to see which one gives you the best performance:

./build charm++ mpi-linux-x86_64 --with-production
./build charm++ mpi-linux-x86_64 smp --with-production
./build charm++ net-linux-x86_64 ibverbs --with-production
./build charm++ net-linux-x86_64 ibverbs smp --with-production

The smp builds of Charm/NAMD require slightly different runtime options than the regular builds. Please e-mail us if you have any problems.

       Hello,

       I would like to build the proper version of charm++ for our linux clusters in order to use NAMD2.8

       Based on the specs listed on this website, which build parameters would give me the best charm++ performance

       https://computing.llnl.gov/?set=resources&page=OCF_resources#sierra

       In the past, i have built namd/charm++ but the nodes then had only a handful of cpus, now they are a bit more complicated.

       Any suggestions would be helpful.
