Michael LIAO 41310144f6 Fix build with hip-clang 
Two minor issues are solved:
+ Enclose the kernel function with parenthesis as hip-clang defines
  `hipLaunchKernelGGL` as macro.
+ Need to explicitly include <hsa.h> for hip-clang.

Wenkai Du 949d680e49 Fix share memory collision in multi-communicator case. (#93) 
Current SHM object name would only use pidHash and ranks as
identification, which would collide each other when program runs with
multiple communicators. Here we added commId info into pidHash, it makes
'pidHash'es of different communicators keeping in same process will be
distincted with each other.
