Con Kolivas
3c3fbdce1c Remove the rounding-up of the scrypt padbuffer which was not effectual and counter-productive on devices with lots of ram, limiting thread concurrencies and intensities. 2013-03-15 21:48:48 +11:00

69983b778b Revert "Pick worksize 256 with Cypress if none is specified." 
This reverts commit 482322a4b7.

Worksize 256 was only helpful on cypress with ultra-low memory speeds with old SDKs and the new kernels require higher memory clocks, having the opposite net effect.

ea10b08dce Find the nearest power of 2 maximum alloc size for the scrypt buffer that can successfully be allocated and is large enough to accomodate the thread concurrency chosen, thus mapping it to an intensity. 2012-07-25 22:02:14 +10:00

3a0d60cfe1 Always create the largest possible padbuffer for scrypt kernels even if not needed for thread_concurrency, giving us some headroom for intensity levels. 2012-07-23 21:30:30 +10:00
