Detailed Description

Optimal block sizes vary with GPU and, to a lesser extent, CPU.

Tuning of the batched kernels that are invoked on extremely small sizes.

Kepler tuning was on K20c 705 MHz with SandyBridge 2.6 GHz host (bunsen). Fermi tuning was on S2050 1147 MHz with AMD Opteron 2.4 GHz host (romulus).
