1. rewriting memory access generation code (from scratch), why not...
passing CUDA 3.1 and ptxplus correlation, but correlation still bad (0.62)...
after debugging 1 to get it working with ptxplus, problem is very clear:
shared and constant cache accesses not occuring for operations that combine these with ALU operations.
TODO:
have a "read-operands" stage, which somehow combines operand collector
register reading with shared and const memory accesses...
