Folks, Can u shed some light no pros/cons of using e.g. 32-bit vs 64-bit cpus with BioBrew-1.0 distro. Also what do u recommend viz-a-viz hardware that performs best and is robust with BioBrew distribution in regards to e.g. per node : 1. Single or Dual CPU machine 2. 32-bit or 64-bit cpu (intel, amd) ? 3. Recommended motherboard memory ? 4. Recommended motherboard hard-disk (if any) size ? I am still fuzzy on whats the 'recommended' HW configuration for NPACI rocks cluster distribution ...? In other words how does a node look like, just the motherboard with CPU or is there on-board RAM and HD ? Your input ... Please. I mean whats a good HW configuration for the life sciences. Has anyone done some benchmarks ? -Rgds Mamoon Kundi.
