[mpich-discuss] Binary compatibility

[Wesley Bland]

The ABI compatibility initiative applies within the same implementation as well. So all MPICH versions back to MPICH 3.1 are binary compatible with each other.

https://www.mpich.org/abi/ <https://www.mpich.org/abi/>

It’s possible that MPICH 3.0 is also compatible, but I don’t think there were any guarantees or tests. You might just get lucky if that’s the version you want.

Thanks,
Wes
