setGlobalWork

public void setGlobalWork(long x,
 long y,
 long z)

Description copied from interface: WorkerGrid

Sets the total number of threads per dimension to launch on the accelerator.

Specified by:

setGlobalWork in interface WorkerGrid

Parameters:

x -

y -

setLocalWork

public void setLocalWork(long x,
 long y,
 long z)

Description copied from interface: WorkerGrid

Sets the local work group threads per dimension to launch on the accelerator.

Specified by:

setLocalWork in interface WorkerGrid
