Hi All,
I thought I would follow up with a solution. It turns out there is a
bug in glibc that is now exposed in old versions (pre 1.8) of OpenMPI on
Cray XE systems. Thanks to Justin Davis of Cray for figuring it out.
The simple solution is to remount /dev/pts with the gid=5 option turned
Thanks Ralph,
I was afraid that there wasn't a "oh we started..." For what it is
worth, everything up to and including 1.7.x shows the same sort of
failure. The trouble with Jaguar is that they actually embed their own
version of everything inside their code. I once took on the task of

I’m not sure there is a way to do it - that’s a pretty old version, and the RTE
in it is completely different. So entirely possible that something in the
update exposed a problem that no longer works.
Out of curiosity: I’m unaware of any changes in the MPI definitions (there were

Hi All,
We run a Cray XE/XT-7. For normal (ESM) use, Cray supplies
integrated MPI libraries. However, for cluster compatibility mode, we
build OpenMPI to use. Generally we use 1.8.4 but some old packages,
