Hemant, Thanks for the laugh, I needed it. Today was rough. Every time we write code, we literally sit down and try to run a simulation in our head of a processor that can retire millions if not billions of instructions per second, multiplied by dozens of parallel instances. Our brain isn’t built for that. It was hard enough in 1970 when you only had to simulate a few hundred instructions in your head. A compiler doesn't fix that, and, in fact, it can make the problem worse. Can we get back to vpp now? Jim
