文摘

In the spring of 1993 a number of highly used third-party packages were selected for porting to the Cray MPP which was to be delivered to the Pittsburgh Supercomputing Center later in the year. Using the T3D Emulator and a cluster of Alpha workstations and eventually the MPP hardware in Eagan and Pittsburgh these packages were successfully reimplemented with varying degrees of difficulty. In this paper we will describe for three of those packages: the major difficulties, the novel solutions and current performance relative to the Cray C90.
