[mpich-discuss] Issue with OrangeFS 2.9.7 direct interface and MPICH 3.3.1 using CH4 device

[Si, Min]

Hi Kun,

Can you please try to reproduce the issue in a simple MPI program which does not use OrangeFS ? It is hard for the MPICH community to help when mixing MPI and OrangeFS together, because we are not OrangeFS experts.

Besides, for InfiniBand networks, you might want to use `ch4:ucx` instead of  `ch4:ofi`. But I do not think it causes the failure in your use case.

Best regards,
Min

To Whom It May Concern,

Recently, I switched to CH4 device in MPICH 3.3.1 for better network performance over the RoCE network we are using.
I realized that my code fails to run when I use direct interface of OrangeFS 2.9.7. It exits without any error. But even simple helloworld cannot print anything. It happens only when I enable direct interface of OrangeFS by linking -lorangefsposix.
Could you please help me on this issue?
Here are some information that might be useful:
