Add MAX_THREADS_PER_BLOCK macro to CUDA kernels. It defaults to 1024 or a lower value if limited by the plugin module or specified via the -T command line option.
For CUDA, lower the C++ dialect from C++17 to C++14 to reduce JIT compile time. Also add support for --split-compile and --minimal flags to further improve NVRTC compile performance.
Remove power-hungry NVIDIA settings and fix missing sudo calls in tools/benchmark_deep.pl.
Remove NEW_SIMD_CODE macro from kernels that do not support SIMD (no u32x).
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.
Add support for lower iteration counts per kernel invocation than the default, enabling TMTO for low scrypt configurations, such as N=1024
Use TMTO 2 if it reaches 4 times the device processor count, instead of TMTO 1 always
Improve performance for low scrypt configurations (hash-mode 9300)
Fix unit test for 15700 with correct scrypt configurations
Disable CPU over subscription for SCRYPT based algorithms
Remove existing tuningdb entries due to salsa_r() core
refactor. Update tuningdb engine to prefer file entries,
when available, over automatic discovery.
Improve memory-free detection per device, default
--backend-device-keepfree is now set to 0.
Old brute-force OpenCL behavior can be restored using
--backend-device-keepfree 100.
