[mvapich-discuss] MPD related error

[Dhabaleswar Panda]

Thanks for your note. You might have noticed that a new version of
MVAPICH2 (1.2RC1) was released a few days back. This release has a non-MPD
(daemon-less) startup scheme. This new start-up scheme is applicable for
all interfaces including uDAPL. I will suggest you to upgrade your
software stack to this release. It will provide you faster start-up and
you need not worry about the MPD-related issues.
