Charm++ parallel programming system

["Choi, Jaemin" <jchoi157 AT illinois.edu>]

Hi Kosar,

The reason that the Infiniband version of Charm++ won't build inside your VM is most likely because it does not have an Infiniband network adapter.

It is meant to be built on clusters/supercomputers with the Infiniband interconnect (and supports the Verbs API).

Please let us know if you have more questions.

Hello dear NAMD developers

I tried to compile NAMD source code, however I recieved below error and the process has stopped working.

machine.c: In function ‘machine_exit’:
machine.c:327:3: warning: implicit declaration of function ‘EmergencyExit’ [-Wimplicit-function-declaration]

I was in below step;

Build and test the Charm++/Converse library (single-node multicore version):
  cd charm-6.8.2
  ./build charm++ multicore-linux-x86_64 --with-production
  cd multicore-linux-x86_64/tests/charm++/megatest
  make pgm
  ./pgm +p4   (multicore does not support multiple nodes)
  cd ../../../../..

Build and test the Charm++/Converse library (ethernet version):
  cd charm-6.8.2
  ./build charm++ netlrts-linux-x86_64 --with-production
  cd netlrts-linux-x86_64/tests/charm++/megatest
  make pgm
  ./charmrun ++local +p4 ./pgm   (forks processes on local node)
  cd ../../../../..

Build and test the Charm++/Converse library (InfiniBand version):
  cd charm-6.8.2
  ./build charm++ verbs-linux-x86_64 --with-production

I did not understand what was the problem. I have google it. maybe the space was not enough on my drive! I was trying to install it on virtual linux!

Thank you for consideration.

Best

Kosar
