(abstract) User Support for an MPP, JPL Begins the Process
The issue of training end-users and center staff in the effective utilization of Cray Research computers is a constant, on-going process at most all sites. Problems such as training materials, class frequency, videos, and site-specific information are very important components in this area. Panel members will offer a varied approach to technical training, and CRI will present possible solutions as well.
