I found my problem, which had to do with incorrect library loading (LD_LIBRARY_PATH). There was a different mvapich (0.9.5) being loaded instead of the new one. Perhaps a version check with a nice error message could help in the future.
However, mvapich gen2 works just fine according to my preliminary tests.

FYI, we are also running the latest version successfully on multiple platforms (IA32, Opetron and EM64T) of different sizes. We are also able to run applications successfully. To the best of our knowledge, many other organizations are also running mvapich-gen2 successfully on their platforms. > Federico> Adding the -debug flag to mpirun_rsh does not help (the > Federico> xterms flash on then dissapear).

As Roland indicates, could you please provide more details on the platform, OpenIB version (kernel, userlib), and the errors you are getting. This will help to debug the problem further and faster. > Also, it might be worth contacting the MVAPICH developers by emailing > mvapich_request -- they are much more likely to be able to help than > the openib-general community. We at OSU are monitoring the OpenIB list for mvapich-gen2 related questions and are answering them. In addition, if you can send a copy to [EMAIL PROTECTED] (not mvapich_request), we will be able to respond even faster.
