I want to apply feature selection on a dataset with some 30-40K columns and 100 rows ( total size: 400MB-800MB ). To decrease the time consumed for calculations involved (feature-feature), I want to divide data in some 4-5 parts and execute all parts parallely. Since data is not huge in size, I am avoiding to use Hadoop. What can be the option for this parallelization.. ( multi-threading , GPU or anything else) ??
