• Buy cycles from CAC (RedCloud, minimum of $400 for 8585 core*hours hour
  • http://www.cac.cornell.edu/RedCloud/start.aspx^{Image Added}
  • 12 cores available at any one time on one system.
    • Can access more than one system at a time, but systems are not linked.
  • $400 (minimum) buys you 8585 core*hours
    • This comes out to ~1 core for an entire year, non-stop.
  • For 96 cores, that's $38.4K for 1 year, non-stop.(They have a max of 96 cores <http://www.it.cornell.edu/about/projects/virtual/test.cfm^{Image Added}>.)
    • 96 = 8 nodes, each with dual 6-core procs => 8 * 12 = 96
  • Or, for $25K, that's ~536,562 cores*hours.
    • $25K = $400*62.5 units. And each unit is 8585 core*hours, so 62.5 of them gets you 536,562.5 cores*hours.
    • That comes to ~178,854 core*hours/ yr for 3 years. Which is 20.8 core system running non-stop each year. (Compare to one hardware node, which has 12 cores.)

Host hardware at CAC rather than with ChemIT

Hosting costs at CAC is for basic: Expert initial configuration, then keep the system current, and keep the lights running. Other service charged hourly.
