I have added configuration files for VIP, a Power6 p575 machine at
RZG. This machine has 32 cores per node, and each core can execute
two threads simultaneously (hyperthreading). There are 2 GByte per
core, or 1 GByte per thread available. I am running benchmarks, and
the performance looks quite good -- hyperthreading is definitively a
benefit. So far I have data up to 256 cores; higher core counts are
waiting in the queue.
The machine looks ready for production use, with queue wait times of a
day or two, and a maximum queue time of one day. I assume that
everybody at the AEI (and collaborators) could get access to this
