@item minp
Set minimal partition size used for convolution. Default is @var{8192}.
Allowed range is from @var{1} to @var{32768}.
Allowed range is from @var{1} to @var{65536}.
Lower values decreases latency at cost of higher CPU usage.
@item maxp
Set maximal partition size used for convolution. Default is @var{8192}.
Allowed range is from @var{8} to @var{32768}.
Allowed range is from @var{8} to @var{65536}.
Lower values may increase CPU usage.
