- The NYU Ultracomputer Project
- The NYU Ultracomputer Lab conducts research in parallel computer
architecture and software design. Specifically, we have constructed two
generations of shared memory machines: an 8 processor bus-based machine in the
1980's and, our current prototype, a 16 processor, 16 memory-module machine
with custom VLSI switches supporting the Fetch-and-Add coordination primitive.
This design allows for a reduction in memory hot-spot contention by
interleaving memory addresses between the memory modules, and using the
network switches to combine requests destined for the same memory location.
The Ultracomputer runs Symunix, a locally developed, parallel version of Unix.
