In the latest MVAPICH 1.0 series (including 1.0.1), a new scalable job
start-up scheme has been introduced. There have been also multiple other
enhancements since 0.9.9. Thus, it will be good to recompile all your
applications to take advantage of these latest features and enhancements.

Also, there is no OFED 1.3.2. I believe you are referring to OFED 1.3.1?

Thanks,

DK
