Lock-step processing

Anonymous's picture

I had always assumed HPC systems did their processing in a lock-step fashion, but I guess that's not true.

There are multiprocessor embedded systems that trigger their time slices and perform their I/O to each other in lock-step in order to manage the latencies and bandwidth. And, when one process is executing, another's I/O is being transferred.

The link for the Cray XD1 Datasheet should be (note: Capital "D" in "Datasheet").
