Do not adjust kernel-accel or scrypt-tmto for GPUs with unified memory, typically integrated GPUs in CPUs (APUs). Redesign the "4-buffer" strategy to avoid overallocation from naive division by four, which can significantly increase memory usage for high scrypt configurations (e.g., 256k:8:1). Update the scrypt B[] access pattern to match the new "4-buffer" design. Allow user-specified kernel-accel and scrypt-tmto values, individually or both, via command line and tuning database. Any unspecified parameters are adjusted automatically. Permit user-defined combinations of scrypt-tmto and kernel-accel even if they may exceed available memory.
