* Implementation CalculateAverage_japplis of 1BRC from Anthony Goubard (#271)Anthony Goubard2024-01-103-0/+264
| | | | | | | | | | * Implementation CalculateAverage_japplis of 1BRC from Anthony Goubard (japplis). Local performance (7 years old desktop i7-6700K - 8 cores - 16GB) 26 seconds. For reference, Jamie Stansfield (isolgpus) is 23 seconds on my machine and 11s in your results. I've added the nbactions.xml to the .gitignore file. When you add in NetBeans options like --enable-preview to actions like debug file or run file, it creates this file. * Implementation CalculateAverage_japplis of 1BRC from Anthony Goubard (japplis).

* Add CalculateAverage_couragelee Java class and shell scriptCourageLee2024-01-102-0/+355
| | | This commit introduces a new java class, CalculateAverage_couragelee, and a shell script for calculating averages. The java class utilizes NIO's memory-mapping and parallel computing techniques to perform calculations. These changes should improve the efficiency and speed of average calculations.
