High Performance Computing Survey

By Brady Black

I am currently an intern at the University of North Carolina, where we are in the middle of the design phase for a new 64 CPU cluster. This survey was created to gather information about what other cluster administrators have discovered and to provide insight into different/better/worse ways of accomplishing cluster administration.

Please be assured that the information gathered from this survey will be used to provide a better understanding of current issues facing the High Performance Computing industry and will not specifically mention any participants unless specific consent is received. If you would like a copy of the aggregate results please let me know at the bottom of the survey. About the author.
