Hi all,
I have a problem using multi USRPs with multi-processes.
I need to use two USRPs connected to a single host, and there are two
applications that invoke two USRP with DPDK enabled.
The first application successfully started, however when I ran the second
one, it gave me the following error message.
I learned that DPDK supports multi-process, and it needs to be set with
--file-prefix.
But I couldn't find any reference for UHD to use multi-DPDK.
Does anyone have any knowledge about this? How can I use multiple USRP with
DPDK in a multi-processing scenario?
Thank you in advance.
