It looks as if your .machines file is OK, I assume that you added the A*** in front for emailing, but Wien2k does not use a hosts file itself. I guess that you are using a server at ibm in almaden. Unfortunately very few people that I know of are running WIen2k on ibm/aix machines which is going to make it very hard for anyone to give useful advice remotely by guessing.
I suggest that you download the benchmarks from http://www.wien2k.at/reg_user/benchmark/ and run these then compare the times. Beyond that get help from someone at ibm who knows the poe command. Or try something more standard such as openmpi which many people know.
