I would like to know the views of the cluster gurus on multi-rail clusters, esp, quad rail networks. Are quad rail networks practical to implement ( say InfiniBand, Quadrics, Myrinet, (GE, maybe not?)). - What are the issues? - Are there any quad rail HPC clusters? (me and google couldn't find any) - Are drivers an issue? - Does the performance increase significantly to justify the cost and complexity? The assumption is that the plan is to solve comm or BW crippled apps, on large SMP nodes (say 8+ CPUs). Note: I found just one line in a CLRC Daresbury lab presentation about quadrail Quadrics on Alpha (probably QsNet-1?) Any update on QsNet2/Eagle? Thanks!
