I want to run NAMD on our intel omni-path cluster.

According to the installation guide, ofi network layer should be chosen to get better performance.

I followed the recipet from intel developer zone :

https://software.intel.com/en-us/articles/recipe-building-namd-on-intel-xeon-and-intel-xeon-phi-processors-for-multi-node-runs

I built charm++ ofi-linux-x86_64 ofi-linux-x86_64, but when I tried to use charm++ to build app(simplearrayhello or megatest in charm++ built-in tests folder), I got the following error message:

../../../bin/../lib/libconv-core.a(convcore.o): In function `CmiTimerInit':
convcore.c:(.text+0x6435): undefined reference to `CmiBarrierZero'

Other users also mentioned this issue in the comment of intel recipet, but the author has not reply yet.

Any suggestions are welcome.

Thanks

A.C.
