[mpich-discuss] Question about counting the mutex waiting time

[Yongyu Chen]

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!
Sincerely,
Yongyu Chen
