…xposed MIDDLE_LDS_TRANSPOSE setting with -use. Intel Battlemage reportedly prefers LDS transpose off.
…g every 100K or 1M iterations. I did not add this to the --help output in case you want to keep the option hidden.
Added -use ZEROHACK_H=1 in tailSquare to mirror the code in carryFused.
This is the best setting on Intel, AMD, and nVidia (at last until the next rocm optimizer change :)
Wrote alternate chainmul8 that uess fewer F64 ops (faster on low DP GPUs) but has worse roundoff error. We will need data from some of these GPUs to decide if this chainMul8 version should be made an official FFT spec option. Cleaned up terminology in math.cl csq and ccube macros. Eliminated FancyUpdate macros. There may be slight improvement in Z values.
More importantly, improved Z value
This version uses fewer F64 ops, but is slower on Radeon 7 -- probably the rocm optimizer acting up. New version is disabled. I'll ask some users to see if it will be beneficial on other GPUs.
