Hi,
I'm trying to run amber10 on a supermicro machine with 2 Intel QCs and 24GB RAM. Ubuntu 9.04 is installed and all packages are up to date. I'm running it as well on a desktop with 1QC and 4GB RAM. Both machines have the same OS and patch levels. On the desktop it seems to run normally but on the supermicro it goes into a loop calling gettimeofday. This does not seem to related to MPI as the serial version does the same.
Thanks
John
