Re: is there in gnuradio a library that for for,loop case execute parallel computing like open mp?

[Marcus Müller]

RAM very much has a speed limit! It's unlikely you hit it at these very low 
sampling
rates, though.

if you're using this low sampling rate, then it's not clear why you'd want to 
multithread.

You need to very clearly write down why you think parallelizing solves your 
problem – and
what exactly that problem is!

Best regards,
Marcus
