topic Hi Yu-Ping, in Intel® MPI Library

I_MPI_WAIT_MODE don't work

Yu-Ping_Z_Intel — Thu, 22 Sep 2016 03:33:32 GMT

I find this parameter I_MPI_WAIT_MODE on Intel MPI 2017 reference guide. It said that "Use the Native POSIX Thread Library* with the wait mode for shm communications". My application is MPI + Pthread. MPI is intel MPI2017

So I add “export I_MPI_WAIT_MODE=1” into my scripts, it print the following error. Do you have some suggestion? thanks

Hi Yu-Ping,

Hi Yu-Ping,

Would it be possible to get a small reproducer? And did you check other interconnects e.g I_MPI_FABRICS=dapl already?

Best regards

Hello Klaus-Dieter:

Thanks a lot for your great help. I_MPI_FABRICS=dapl can work well with I_MPI_WAIT_MODE=1. So what is your suggestion？

I would still like to get a

I would still like to get a small reproducer. I will contact you directly by mail.
