[dpdk-users] DPDK 19.11 can't work in a multi PRIMARY mode

[Yan Fridland]

I’ve noticed that the string “--in-memory” is mandatory in this mode. However, it was not mentioned in the documentation in the website and the description was a bit not clear:
“Do not create any shared data structures and run entirely in memory.”

I must say that in EAL help its much clearer: “Operate entirely in memory. This will disable secondary process support”

Thanks,
Yan

Can you paste the whole command you're running? --file-prefix with unique strings afterward should allow you to do that.

Hi Guys,

I am trying to use the --file-prefix to run several independent PRIMARY processes on the same VM (--proc-type=primary for all the processes).
The problem is that it doesn’t work and I am getting the following error:

"EAL: Cannot create lock on '/var/run/dpdk/rte/config'. Is another primary process running?"

Can anyone assist in resolving this issue ?


Thanks
Yan
