This isn't necessarily the same as maxDynamicSharedMemoryPerBlock since that may need explicit opt in to enable (by calling setMaxDynamicSharedBytes for the kernel in question). If the CUDA kernel in question does this opt in then this function can be overloaded to return maxDynamicSharedBytesPerBlock. More...

Detailed Description

This derived class is for algorithms that deploy parity across the y dimension of the thread block with no shared memory tuning. The x threads will typically correspond to the checkboarded volume.

Member Function Documentation

advanceBlockDim()

bool quda::TunableLocalParityReduction::advanceBlockDim ( TuneParam &  param ) const

inlinevirtual

Reimplemented from quda::Tunable.

Definition at line 439 of file tune_quda.h.

defaultTuneParam()

void quda::TunableLocalParityReduction::defaultTuneParam ( TuneParam &  param ) const

inlinevirtual

sets default values for when tuning is disabled

Reimplemented from quda::Tunable.

Definition at line 450 of file tune_quda.h.

gridStep()

int quda::TunableLocalParityReduction::gridStep ( ) const

inlineprotectedvirtual

gridStep sets the step size when iterating the grid size in advanceGridDim.

Returns

Grid step size

Reimplemented from quda::Tunable.

Definition at line 428 of file tune_quda.h.

initTuneParam()

void quda::TunableLocalParityReduction::initTuneParam ( TuneParam &  param ) const

inlinevirtual

Reimplemented from quda::Tunable.

Definition at line 445 of file tune_quda.h.

maxBlockSize()

unsigned int quda::TunableLocalParityReduction::maxBlockSize ( const TuneParam &  param ) const

inlineprotectedvirtual

The maximum block size in the x dimension is the total number of threads divided by the size of the y dimension. Since parity is local to the thread block in the y dimension, half the max threads in the x dimension.

Reimplemented from quda::Tunable.

Definition at line 436 of file tune_quda.h.

minGridSize()

unsigned int quda::TunableLocalParityReduction::minGridSize ( ) const

inlineprotectedvirtual

Reimplemented from quda::Tunable.

Definition at line 427 of file tune_quda.h.

sharedBytesPerBlock()

unsigned int quda::TunableLocalParityReduction::sharedBytesPerBlock ( const TuneParam &  param ) const

inlineprotectedvirtual

Implements quda::Tunable.

Definition at line 418 of file tune_quda.h.

sharedBytesPerThread()

unsigned int quda::TunableLocalParityReduction::sharedBytesPerThread ( ) const

inlineprotectedvirtual

Implements quda::Tunable.

Definition at line 417 of file tune_quda.h.

tuneGridDim()

bool quda::TunableLocalParityReduction::tuneGridDim ( ) const

inlinefinalprotectedvirtual

Reduction kernels require grid-size tuning, so enable this, and we mark as final to prevent a derived class from accidentally switching it off.

Reimplemented from quda::Tunable.

Definition at line 425 of file tune_quda.h.
