Charm++ parallel programming system

["Bennion, Brian" <Bennion1 AT llnl.gov>]

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.
