virtual bool quda::Tunable::advanceSharedBytes ( TuneParam & param ) const

inlineprotectedvirtual

The goal here is to throttle the number of thread blocks per SM by over-allocating shared memory (in order to improve L2 utilization, etc.). Note that:

On Fermi, requesting greater than 16 KB will switch the cache config, so we restrict ourselves to 16 KB for now.
On GT200 and older, kernel arguments are passed via shared memory, so available space may be smaller than 16 KB. We thus request the smallest amount of dynamic shared memory that guarantees throttling to a given number of blocks, in order to allow some extra leeway.
