Dear sir or madam,

 

I’m currently working on a project with mpich.

I faced some difficulties when I would like to count the mutex waiting time, just like what they did on the paper, Fine-Grained Multithreading Support for Hybrid Threaded MPI Programming.

I could not find the definition of the function, MPID_THREAD_CS_ENTER(GLOBAL, MPIR_THREAD_GLOBAL_ALLFUNC_MUTEX).

If you could provide me more detailed information, I will appreciate it.

Thank you in advance!
