We thought there was a silent data corruption issue on POWER 7/BE systems, so we blocked building on POWER 7/BE systems altogether. We later figured out that it was just data hangs -- not silent data corruption. So in hindsight, the configure block probably wasn't necessary -- but we didn't know it at the time. Regardless, the hangs have now been fixed, and we're removing the POWER 7/BE block in configure. For more detail on the entire saga, see open-mpi#4349 (comment). Signed-off-by: Jeff Squyres <[email protected]> (cherry picked from commit 3f0ccff)
Also note that ARM and POWER users may experience hangs (until open-mpi#4563 is fixed). Signed-off-by: Jeff Squyres <[email protected]>

There was a problem hiding this comment.
The other PRs had a change to the README - https://github.com/open-mpi/ompi/pull/5052/files#diff-c47c7c7383225ab55ff591cb59c41e6b - is that needed on this branch too?

@jjhursey No; that blurb already exists here in the v3.0.x README. |

Per #5034 and larger discussion on #4349.
Still waiting for #4563 to be fixed (to resolve hangs on some ARM/POWER platforms), but that's a different issue.
