The Original LoBoS Configuration

The original LoBoS has been completely turned into desktop machines. The compute nodes had point-to-point connections supporting simultaneous data transfer over the network's ring topology. LoBoS was originally comprised of a ring of 64 dual-processor Pentium Pro 200 MHz compute nodes (128 processors). The compute nodes had point-to-point connections supporting simultaneous data transfer over the network's ring topology.
