One of the first IBM parallel processing computers—the
SP1™—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 SP2™
software environment using the SP2 communication adapters, the use of
the emerging
MessagePassing Interface standard, and the continued use of the SP1
processors
have been successful.
