25c39c96bb Ease the checking on allocation of padbuffer8 in the hope it works partially anyway on an apparently failed call. 2012-10-15 12:31:57 +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.

4fbe5bed15 OpenCL 1.0 does not have native atomic_add and extremely slow support with atom_add so detect opencl1.0 and use a non-atomic workaround. 2012-08-23 23:25:32 +10:00

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
