# you can use simple :p or :parallelism as nametag
# remember :parallelism is all about real OS thread case, so
# you CANT modify the objects in memory only in sharedmemories,
# the normal variables will only be copy on write modify
# This is ideal for big operations where you need do a big process
# w/o the fear of the Garbage collector slowness or the GIL lock
# when you need to update objects in the memory use SharedMemory
