Helo all,
I just released new binaries (ending with build5) in the same old place (see first post). Those binaries use a new sha512 code, tuned and optimized by my during the last few days. It is at least 15% faster than the old code.
Short Version: faster! gpuv7 is default, gpuv9 is the low memory mode.
TLDR version: The new "-a" options "gpuv7", "gpuv8" and "gpuv9" all use the new code. "gpuv9" is the low memory version, same as "gpuv3", using the new sha512 code. "gpuv8" is the same as "gpuv4" with the new code, and "gpuv7" is based on "gpuv6", but uses a linear collision avoidance hashtable instead of the plain hashtable used before. It is bound to find slightly more hashes at the cost of being a little bit slower. since in all my tests it produces better CPM, i made "gpuv7" the default mode. The old modes are still kept for compatibility (maybe my optimizations are not compatible with all GPUs, then you can always fall back to the old modes).
Please download and enjoy.
Thanks,
girino.
