[mpich-devel] porting MPICH to CHERI - dumb questions

[Jeff Hammond]

I am trying to port MPICH to CHERI (
https://www.cl.cam.ac.uk/research/security/ctsrd/cheri/cheri-morello.html).

I have forgotten some of the tricks of porting to weird stuff that I used
to know when I was working on Blue Gene.

Can someone help me figure out how to configure for an unknown tuple?  I am
failing to find the answer myself.

Thanks,

Jeff
