Hi mpich dev team,
I am facing one issue similar to discussed in below discussion
Someone in the mailing list suggested recompiling the mpi bench using
CH4. as below:
"MPICH with ch4, with `--with-device=ch4:ofi`"
Actually this fixes the failure on this CPU architecture.
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
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.
