I think the problem it has is it only deal with the old framework because it will intercept MPI calls and do some profiling. Here is the library: https://github.com/LLNL/Adagio
I checked the openmpi changelog. From openmpi 1.3, it began to switch to a new framework, and openmpi 1.4+ has different one too. This library only works under openmpi 1.2. Thank you for your advise, I will try it. My current problem is this library seems to try to patch mpi.h file, but it fails during the patching process for new version openmpi. I don't know the reason yet, and will check it soon. Thank you. Kaiming Ouyang, Research Assistant.
