In 1994, Convex introduced an entirely new design, known as the '''Exemplar'''. Unlike the C-series vector computer, the Exemplar was a parallel-computing machine that used HP [[PA-7200]] microprocessors, connected together using [[Scalable Coherent Interconnect|SCI]]. First dubbed '''MPP''', these machines were later called '''SPP''' and '''Exemplar''' and sold under the '''SPP-1600''' moniker. The expectation was that a software programming model for parallel computing could draw in customers. But the type of customers Convex attracted believed in [[Fortran]] and brute force rather than sophisticated technology. The operating system also had terrible performance problems which could not easily be fixed. Eventually, Convex established a working partnership with HP's hardware and software divisions. Initially it was intended that the Exemplar would be binary-compatible with HP's [[HP-UX]] operating system but eventually it was decided to port HP-UX to the platform and sell the platform as standalone servers.

In 1995, Hewlett-Packard bought Convex. HP sold Convex Exemplar machines under the '''S-Class''' (MP) and '''X-Class''' (CC-NUMA) titles, and later incorporated some of Exemplar's technology into the '''V-Class''' machine, which was released running the HP-UX 11.0 release instead of the SPP-UX version which was sold with the S- and X-Class products.
