The output differs from the expected one for the 10K key set now:
Validating calculate_average_zerninv.sh -- measurements_10K_1B.txt
Picking up existing native image 'target/CalculateAverage_zerninv_image', delete the file to select JVM mode.

@gunnarmorling would you mind to check it one more time. locally outputs match with baseline (or top) solution.
00:03.785 now, passing for the 10K keyset too. Nice!

Hey @gunnarmorling, Thanks again for this challenge. My random is: 11960 13079
Check List:
[x] You have run
./mvnw verify
and the project builds successfully[x] Tests pass (
./test.sh zerninv
shows no differences between expected and actual outputs)[x] All formatting changes by the build are committed
[x] Your launch script is named
calculate_average_zerninv.sh
(make sure to match casing of your GH user name) and is executable[x] Output matches that of
calculate_average_baseline.sh
[x] For new entries, or after substantial changes: When implementing custom hash structures, please point to where you deal with hash collisions (line number)
Execution time: 13s
Execution time of reference implementation: 6m
I see that my solution gives segfault for 10k dataset. Unfortunately can not reproduce it locally so change my solution a bit as an attempt to avoid segfault
