* Smoofie solution. Kinda slow but it was fun :)
* Format according to mvn build
* Fix semicolon detection, which cause invalid temperature parsing and subsequently segmentation faults due to counter addressing
* dpsoft: first submission
* minor clean up
* map with linear probing
* clean up
* update prepare
* clean up
* remove string format
* add credits
* fix format
* use prepare.sh
* graal 21.0.2
* fix differences
* clean up
* underflow protection
* improve segments generation logic
* clean up
* remove unnecessary alignment in findsegment
* new try
* fix number of segments
* CalculateAverage_pdrakatos
* Rename to be valid with rules
* CalculateAverage_pdrakatos
* Rename to be valid with rules
* Changes on scripts execution
* Fixing bugs causing scripts not to be executed
* Changes on prepare make it compatible
* Fixing passing all tests
* Increase direct memory allocation buffer
* Fixing memory problem causes heap space exception
* Fresh solution to optimize performance of the execution
* New Fresh solution with optimized performance with Custom Hashtable
* Increase maxperm size and xmx to avoid heap spaces error
* Exit earlier from loop when a new Result is created
* 3) Make a cache of long[] name to String, to avoid `ByteBuffer.allocate`
* and creating new UTF-8 strings. I didn't profile, so it's just a guess
* that this map will be a bit faster. Although it's outside the main loop, so
* not a big difference ...;
* 4) Exit earlier from loop if a new entry was created.
* revert: Remove cache to city name
* As I was not able to make it faster... make it slower
As I was not able to make it faster ... so I'll make it slower,
because my current solution should *not* stay at the top, as it added
basically nothing.
* Combine <8 and 8-16 cases into one case.
* Adopt mask-based approach for the <16 length city fast path (idea of Van Phu Do).
* Slightly improved code layout.
* Update perf number.
- use smaller regions (increased region count) so there will be less idle time for the workers who completed their tasks
- get rid of some configuration related stuff during initialization which might save a few tens of milliseconds hopefully
- update temperature value parsing instruction order to get benefit of ILP better (hopefully)
* decrease instruction level parallelism
it turns out doing 2 things was too much. perf annotate showed spilling.
* more trickery with latency hiding
* work-stealing, lookp tables, credits
* do not assume gender
* Disable The GC
Cuts off sometimes up to 1 seconds
of runtime on my machine.
* Remove Confusing Byte-Order Parameter
Bytes have no Byte-Order ;)
* Provide More Memory to Run the 10K set
* Fix Comparison Function
* Justin's implementation
* Rename justin to Judekeyser
* Back to previous implementation of vectors
* Reading names as sequences of integers
* Fixing tests
* Scale down the number of NIO workers

instead of writing result line by line, implemented random.choices for randomisation of multiple stations and writing large batche ot the disk, also instead of "round" just using :.1f which is probably quicker on a large scale, because it's not a mathematical function
