* Some clean up, fine tuning, removing non-supported options, added credit
section and additional comments.
* Put license header year back to 2023 to pass checks.
* Remove static linking (as it requires some more setup on the target
machine).
* Some clean up, small-scale tuning, and reduce complexity when handling longer names.
* Do actual work in worker subprocess. Main process returns immediately
and OS clean up of the mmap continues in the subprocess.
* Update minor Graal version after CPU release.
* Turn GC back to epsilon GC (although it does not seem to make a
difference).
* Minor tuning for another +1%.
* Optimize checking for collisions by doing this a long at a time always.
* Use a long at a time scanning for delimiter.
* Minor tuning. Now below 0.80s on Intel i9-13900K.
* Add number parsing code from Quan Anh Mai. Fix name length issue.
* Include suggestion from Alfonso Peterssen for another 1.5%.
* Optimize hash collision check compare for ~4% gain.
* Add perf stats based on latest version.
* Initial version.
* Make PGO feature optional off-by-default. Needs PGO_MODE environment
variable to be set. Add -O3 -march=native tuning flags for better
performance.
* Adjust script to be more quiet.
* Adjust max city length. Fix an issue when accumulating results.
* Tune thomaswue submission.
mmap the entire file, use Unsafe directly instead of ByteBuffer, avoid byte[] copies.
These tricks give a ~30% speedup, over an already fast implementation.
* Optimize parsing of numbers based on specific given constraints.
* Fix for segment calculation for case of very small input.
* Minor shell script fixes.
* Separate out build step into file additional_build_step_thomaswue.sh,
simplify run script and remove PGO option for now.
* Minor corrections to the run script.
