Re: [Discuss-gnuradio] How do I interface my X310 with an NVIDIA K80 GPU in GNURadio

[Derek Kozel]

Hello LJ,

It would help to know what type of signal processing you are hoping to do and how you want to display or save the data. On generally available consumer hardware GNU Radio has been shown to be able to handle 800+MS/s of samples being displayed in spectrum plots.

It sounds like you are trying to route too much data to your speakers. Are you able to share your flowgraph? There is a screenshot function in the menu or the grc file could be attached.

Regards,

Derek

Hi LJ Eads,

I'm a bit confused: What has your sound card to do with GNU Radio, or
the USRP? And how is your sound card comparable to a GPU?

GNU Radio runs on CPUs.

Best regards,
Marcus

I have everything working and functioning properly (drivers and all) but my only concern right now is that GNURadio is running off of the sound card on my server and not the GPU. GNURadio isn’t able to handle practically anything because I am limited by the sound card capability.
