Charm++ parallel programming system

[pellegrini <pellegrini AT ill.fr>]

Hello,

we are trying to install NAMD on our new DALCO cluster made of 43 
8-cores Intel Xeon cpus (Nehalem) connected through InfiniBand. We 
followed the installation notes but we fails to make charm++ work. The 
build was successful but when performing some tests we got no results. 
We are using charm-6.1.3 that comes along
with NAMD-2.7b2. We did the following from the NAMD directory:

1 cd charm-6.1.3
2 env MPICXX=mpicxx ./build charm++ net-linux-x86_64 pgcc 
--basedir=/usr/pgi/linux86-64/2010/mpi/mvapich --no-build-shared pgf90 
ibverbs --no-build-shared -j32 -O2 -DCMK_OTIMIZE --> the build was 
successful
3 cd tests/charm++/megatests
4 make clean
5 make pgm --> the make was successfull
6 charmrun ++local +p4 ./pgm and from here we get:

   Charmrun> IBVERBS version of charmrun
   Charmrun: Bad initnode data length. Aborting

Based on this, the build of NAMD works but once again the tests are 
failing. We think that both failures are related.

Would you have any idea of what is going wrong or if we did some 
mistakes when building charm++ ?

thank you very much

best regards

Eric Pellegrini
