Should fix issue leela-zero#1921.
Required on macOS, and probably other platforms. Fixes issue leela-zero#1901. Pull request leela-zero#1910.
Implement a few more parameters that can be set via lz-setoption, specifically visits, playouts, pondering, resign threshold and the lag buffer. We currently don't check the provided values against the reported min/max values but rely on the UI not to mess up. This could be addressed in a refactoring. Similarly, commandline and setoption values should probably treated in a unified way. Remove the bogus boolean return value from GTP processing functions. Minor style fix for old GTP code. Pull request leela-zero#1927.
We need to call UCTNode::create_children() even if we aren't expanding because that moves our node's state from INITIAL to EXPANDED. Pull request leela-zero#1928.
If tuner failed during precision autodetection error output in stdout was read as a GTP message. Pull request leela-zero#1935.
* Fall back to single precision when the GPU claims fp16 support but it doesn't work. * Net initialization fixes: - Try at least one selfcheck eval when autodetecting precision - Revive selfcheck when using Eigen Pull request leela-zero#1934.
Fixes issue leela-zero#1938.
Many lz-setoption commands are forgetting to add the closing GTP = if they are successful. This will freeze GUIs. Fixes issue leela-zero#1940.
We've supported HTTPS on the server side for a while now, make it the default.
Colab has updated and the instructions here probably no longer work. They should probably be hosted elsewhere, too.
Define a variable closer to the usage point.
* Separate FPU-reduction setting for root. * Removed fpu_root_reduction. Pull request leela-zero#1960.
Link to Google Cloud tutorial on Google Docs. Pull request leela-zero#1961.
Delete outdated questions and answers. Pull request leela-zero#196.
Disabling input buffering on Windows causes breakage that looks like input buffering stays enabled. This was accounted for in the code, but the #define check was against a non-default flag, and a different one as used elsewhere.
Even though SGF defaults to size 19 boards, we should not try to set up a board that size if LZ has not been compiled to support it. Pull request leela-zero#1964.
Without this, it's empirically not possible to load the current 256x40 networks on a 32-bit machine.
If we are trying to auto-select the best device for OpenCL, never select a CPU. This will cause the engine to refuse to run when people are trying to run the OpenCL version without a GPU or without GPU drivers, instead of selecting any slow and suboptimal (and empirically extremely broken) OpenCL-on-CPU drivers. Falling back to CPU-only would be another reasonable alternative, but doesn't provide an alert in case the GPU drivers are missing. Improves behavior of issue leela-zero#1994.
Fix full tuner for heterogeneous GPUs and auto precision detection. --full-tuner implies --tune-only --full-tuner requires an explicit precision Fixes leela-zero#1973. Pull request leela-zero#2004.
Very minor speedup of about 2% with batch size of 1. With batch size of 5 there is a speedup of about 5% with half precision and 12% with single precision. Out transformation memory accesses are almost completely coalesced with the new kernel. Pull request leela-zero#2014.
From upstream a807dcf0f8623d40dc5ce9d1eb00ffd0e46150c7.
* CPUPipe : change winograd transformation constants to an equation. Combined with a series of strength reduction changes, improves netbench by about 8%. * Convert some std::array into individual variables For some reason this allows gcc to optimize the code better, improving netbench by 2%. Pull request leela-zero#2021.
Use hard-coded equations instead of matrix multiplication. Pull request leela-zero#2023.
Fix Validation -k option by reading its value before the parser is reused. Pull request leela-zero#2024.
See pull request leela-zero#2031.
