You should be able to gain some insight by examining your openmpi build logs to see if it builds for both __float80 and __float128 (or neither).

Unfortunately, these are not my machines, so I do not have access to any build logs. But I will talk to the admins and/or
I try to compile openmpi myself.

Best regards,
