Experiences with the IBM SP1

Research output: Contribution to journalArticlepeer-review

Abstract

One of the first IBM parallel processing computers - the SP1TM - and the largest, with 128 nodes, was installed in 1993 at Argonne National Laboratory. It took only days, not months, to prepare for and migrate applications to this parallel supercomputer, demonstrating that high performance, parallelism, and portability can coexist. This paper describes the early experiences with the SP1 at Argonne, which provide lessons for supercomputer system designers and users alike. We explore what features of software technology and system architecture enabled immediate and successful use of the SP1. The paper concludes with a brief indication of why the move to the SP2TM software environment using the SP2 communication adapters, the use of the emerging Message-Passing Interface standard, and the continued use of the SP1 processors have been successful.
