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

[Marcus Müller]

Dear stackprogrammer,

you can write any software you like in a GNU Radio block's work 
function. I'm sure you've done that before!

However, multithreading a single GNU Radio block that only does a 
multiplication or two is almost certainly worse than not doing it. GNU 
Radio itself is a heavily multithreaded environment. So, if you take a 
block that is not a bottleneck, and make it occupy multiple CPU cores, 
you're reducing your overall system performance.

Of course, if you already looked at your system workload, identified 
that the block you want to parallelize is your bottleneck, AND already 
know the type of algorithm you do inside can be done efficiently (!) in 
parallel, well, that's something else. However, in the last email you 
wrote about being throughput-limited, it seemed quite likely that your 
storage speed is limiting you.

Best regards,
Marcus
