Neil

Ex-programmer (mainly C, PERL(/Tk), Javascript) and systems analyst (mainly Unix and some ancient O/Ss), keen on scuba-diving and golf.

I've mainly worked as a systems analyst on supercomputers: Cray-1A to C90 from Cray Research inc, Vector Parallel Processors from Fujitsu and SMT microprocessor systems linked via Infiniband from IBM.

The last system I was responsible for comprised 2 identical supercomputers, each with around 8,700 2-way symmetric multi-tasking processors, each probably more powerful than the PC you are using to read this. The whole system was capable of a sustained performance of about 20 Teraflops (320 Teraflops peak performance - 320 million Megaflops [Megaflops = one million floating-point operations (calculations) per second] - the first true supercomputer (the Cray-1) had a peak performance of 80 Megaflops).
