CPU usage 100 % while execution

Hi,

I run the examples from your module but it uses 100 % CPU execution.Sometimes it never open QT GUI for some reason. Do you have any work around this ?

Can you give some more details like GNU radio version, OS, type of hardware you run it on? Flowgraphs were created for GR 3.7.13 and were not tested on GR 3.8
As a starting point, try to replace the file source with a TCP source in the flowgraphs and verify if issue is still present.

Hi,

I’m running Ubuntu 16.04 and running the same version of GNuRadio 3.7 and i did replace it with tcp source and issue still persists.

Thanks.

I wasn't able to reproduce the issue. It's true that the file source can consume 100% of one CPU thread the way that it's written, but that is a GNU radio implementation detail and it doesn't have anything to do with this module. Also, if you are running on a multi core machine, this should not prevent the flowgraph from working. No other blocks consume that many CPU cycles.
