@InProceedings{duzett:ncube3, author = {Bob Duzett and Ron Buck}, title = {An Overview of the {nCUBE~3} Supercomputer}, booktitle = {Proceedings of the Fourth Symposium on the Frontiers of Massively Parallel Computation}, year = {1992}, pages = {458--464}, keywords = {parallel computer architecture, MIMD, pario-bib}, comment = {Basically the same architecture as the nCUBE/2, scaled up. Eight to 65K processors, each 50 MIPS and 100 DP MFLOPS, initially 50 MHz. RISC. 16 hypercube channels and 2 I/O channels per processor. CPU chip includes MMU, TLB, I- and D-cache, hypercube and I/O channels, and memory interface. The channels have DMA support built-in (5 usec startup overhead, worst-case end-to-end latency 10 usec), and can talk directly to the memory interface or to the cache. 64-bit virtual address space, with 48 bits implemented. Hardware support for distributed virtual memory. Separate 16-node hypercube is used for I/O processing, with up to 400 disks attached. Packaging includes multi-chip module with DRAMs stacked directly on the CPU chip, fluid-cooled, so that an entire node is one package, with the 18 network links as essentially its only external connections.} }
