I am currently running a code with pyspi and encountered some questions.

first I want to know if the pyspi runs any parallel calculations inside its codes or not

secondly, does pyspi uses GPU for calculations?

Third, if I use parallel computation with 32 cores for example, would it result in faster calculation for an EEG signal of 15000 samples and 18 channels? I used a small piece of my data and realized that parallelization causes the code to run longer. This may be due to the small size of the data that I used.
