© 2007 IDC Some Customer Pain Points Clusters are still hard to use and manage  Power, cooling and floor space are major issues  Third party software costs  Weak interconnect performance at all levels  Applications & programming — Hard to scale beyond a node  RAS is a growing issue  Storage and data management  Multi-processor type support and accelerator support Requirements are diverging  High-end — need more, but is a shrinking segment  Mid and lower end – the mainstream will look more for complete solutions  New entrants – ease-of-use will drive them, plus need applications Parallel software is missing for most users  And will get weaker in the near future—Software will be the #1 roadblock  Multi-core will cause many issues to “hit-the-wall” Hard to scale beyond a node Parallel software is missing for most users …. Software will be the #1 roadblock
