Used "in production" at NCSA since May, 1993, the CM-5, a message-passing, distributed memory, massively parallel machine, is well-suited for problems that can be broken into many pieces to be worked on simultaneously. The machine's current configuration provides for a peak speed of 64 gigaflops (billions of floating point operations per second).

The CM-5 is supported by the Sun
Microsystems 2000 SMP, a front-end compile server (the compile
server is the machine on which a compiler translates the source language data
into a language the CM-5 understands), and Sun workstations, all using SPARC
microprocessors and working under the Solaris operating system.

Usage of this machine remains heavy and is projected to remain so for another 12-18 months. Andrew Malevsky, from the Massachusetts Institute of Technology, uses NCSA's CM-5 to run simulations of combustion dynamics, a problem which can be divided into many subsections, each of which is assigned to one of the machine's thousands of processors. It's not a memory-intensive problem, or one that requires a lot of communication between processors, so it's a natural application for a distributed memory machine.
NCSA's CM-5 has:
- 512 nodes
- 16 gigabytes of memory
- 140 gigabytes parallel disk storage system called as Scalable Disk Array (SDA)
