Hi Ralph,
I installed openmpi-1.7.5rc2 and applied r31019 to it. As far as I confirmed, rmaps framework worked fine. However, by chance, I noticed that single ctrl+c typing could not terminate a running job. Twice typing was necessary. Is this your expected behavior? I didn't use ctrl+c to abort for a while, I don't know when it started. At least I can terminate the job by single ctrl+c if I use openmpi-1.7.4. And, for your information, when I hit ctrl+c with more than 5 seconds interval, I get the message below: Abort is in progress...hit ctrl-c again within 5 seconds to forcibly terminate Tetsuya
