MasPar Computer Corporation was a minisupercomputer vendor that was founded in 1987 by Jeff Kalb.

While Kalb was the vice-president of the division of Digital Equipment Corporation (DEC) that built integrated circuits, some researchers in that division were building a supercomputer based on the Goodyear MPP (massively parallel processor) supercomputer.

Samples of MasPar MPs, from the NASA Goddard Space Flight Center, are in storage at the Computer History Museum.

The MasPar architecture is designed to scale, and balance processing, memory, and communication.

The MP-2 PE chip contains 32 processor elements, each a full 32-bit ALU with floating point, registers, and a barrel shifter.

Each ALU, called a PE slice, contains 64 × 32 bit registers that are used for both integer and floating point.

Each PE also has two one-bit serial ports, one for inbound and one for outbound communication to its nearest neighbor.

The 32 PEs on a chip are clustered into two groups sharing a common memory interface, or M-machine, for access.

The chip is implemented in 1.0-micrometre, two-level, metal CMOS, dissipates 0.8 watt, and is packaged in a 208-pin PQFP.

They are accessed by extensions to Fortran and C. Full IEEE single- and double-precision floating point are supported.

Cache is not required, due to the memory interface operating at commensurate speed with the ALU data accesses.

As a gimmick MasPar handed out business cards with an MP-2 PE chip laminated to them.
