Hi mpich dev team, I am facing one issue similar to discussed in below discussion https://lists.mpich.org/pipermail/devel/2021-January/000826.html Someone in the mailing list suggested recompiling the mpi bench using CH4. as below: https://lists.mpich.org/pipermail/devel/2021-January/000828.html "MPICH with ch4, with `--with-device=ch4:ofi`" Actually this fixes the failure on this CPU architecture. Questions: 1. Is this a known issue with MPI bench on the recent CPU architecture? (I am running on ARM's Cortex -A 75), like ch3 is broken? 2. With no error after using CH4, does this mean the CPU is all good? Note: using ch3 was working fine on our previous CPU (A-72) Any input will be really appreciated. -- Regards, Alim
