Hi,
the curandom Generator class initializes generators_per_block number of
generators. This is the relevant code:
@property
@memoize_method
def generators_per_block(self):
return min(kernel.max_threads_per_block
for kernel in self._kernels())
On my machine the kernels have the following max_threads_per_block (for
XORWOW):
In [30]: [i.max_threads_per_block for i in g._kernels()]
Out[30]: [512, 512, 512, 512, 384, 384, 384, 384, 384]
The first four are for the normal and uniform generators. The last ones are
for skip_aheads.
Isn't this suboptimal? If I was only using the generators without
skip-ahead it seems I could safely run 512 threads per block if those were
initialized.
