People in countries outside of the US where investment in HPC results in insufficient resources to meet the growing demand and where not even the peak *national* HPC facility makes the Top 500. For ourselves in a state based organisation our new top of the range cluster has 760 cores, which is more than all our previous clusters combined. We have over 600 registered users from 8 universities and our systems are continuously over subscribed and we have to run our systems to try and get the best throughput. We do use things like cpusets to try and limit the impact that jobs can have on other jobs on the same nodes, and users can request entire nodes for themselves should they so wish, just that their project will be tallied as having used all the cores on that node as they're not available to others. Hmm, that wasn't meant to be a whinge, just that we have to cut our cloth to fit. cheers!
