Parallelization

Quanty is a parallel code that can use several cores using a shared memory setup. In a bash shell you can tell the code how many thread it can use by setting the system variable OMP_NUM_THREADS before you run the code

export OMP_NUM_THREADS=16

That’s all. Note that for a few number of cores the code normally scales well, i.e. 16 cores compared to 1 is about 16 times faster. For many cores this scaling is no longer valid. For a large number of calculations you need to test the optimum on your machine.
