Contains solution for INVXOR problem from March Challenge 2020 contest from CodeChef (main.cpp) which is compiled and tested with different compilation options on University's cluster (G++/ICC compiler)

Also contains custom testcase generator (testGenerator.cpp), which is pretty simple, but produces relatively adequate (not just "-1"-answer) tests

Another program (convol.cpp) which better benefits from optimizations and SIMD extensions is also provided. It computes one-dimensional discrete convolution of pseudo-random generated input of given size and seed (for deterministic testing)

"CS Lab 3 VS" folder contains VS projects for these individual programs and also for the one which was optimized with Intel Parallel Studio XE 2020 (OptimizationTest) and generator for it's input file (OptimizationFileGen)

run.sh is a script used for time-testing different compilation parameters and generating reports.

• 1st argument is the "index" of filenames used. E.g. log$1.txt is the output log file, where $1 is "index";
• 2nd argument is the source file;
• 3rd argument is the input file to be redirected to STDIN of the compiled source;
• 4th argument is compiler for the first subtask (different -O options). For testing extensions icc is used anyway.

qsubRun.sh is launched on cluster from the repository directory to start 5 qsub jobs of run.sh with different first ("index") argument (if they were the same, we could have concurrent writes).

• Arguments 1-3 are passed to arguments 2-4 of run.sh
