The LittleFe project has tried to build systems with reasonable balance between CPU, RAM (quantity and throughput), and network speeds so that even though you were working in a small environment the general patterns of speed-up and scaling that you observed would hold when you moved to “big iron”. Until very recently that meant that the smallest form-factor board we could use was mini-ITX, nothing smaller supported multiple cores and gigabit Ethernet. More recently we have looked for on-board accelerator support as well. Now that boards like the Asus Tinker [1] board are coming out we may be able to reduce size and cost significantly. charlie _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
