Re: Happy days
Same here. My first programming was on a CDC 7600 and much later did loads more serious work on the J932 and SV1e. Cray didn't just provide good hardware, but also cracking good compilers. They could recognize just about the most obfusticated bunch of for-loops as a matrix multiplication and replace the code by some optimized routine from their library. What I really liked about both the SV1e and J932 is how these shared-memory machines managed to attain an average performance of roughly 2/3rds of the theoretical peak. Some really nifty scheduling going on, which is VERY hard to accomplish on clusters.
