LoBoS 5
With the unreliability of the motherboards in LoBoS 4, the Computational Biophysics Section staff decided to switch back to Intel CPUs with Supermicro motherboards. As the Pentium 4 processor was not designed for multiprocessor operations, LoBoS 5 nodes were delivered with dual Intel Xeon processors. Approval for the cluster was granted in June, 2003 and LoBoS 5 was installed in stages between March and December of 2004. The first batch of 88 nodes were equipped with 2.66 GHz Xeons. All subsequent nodes have dual 3.06 GHz processors.
With 190 nodes now in operation, the LoBoS cluster has reached the limits of the physical space available to it on campus. A new, off-campus computer room has been constructed and work is underway to build out LoBoS 6.
