Run multiple instanse of click with same DPDK about click HOT 3 CLOSED

Hi!

This is normal and related to DPDK, please see https://doc.dpdk.org/guides/prog_guide/multi_proc_support.html .

I'm not sure (this repository) mainline Click is compatible with secondary process, as opposed to FastClick that supports also DPDK rings. But you can have independent Click running with the file prefix.

If you run Click without --dpdk, you won't be able to use DPDK so the second part of error messages is expected.

Cheers,
Tom

I don't want to Run several DPDK. I want to run one Dpdk Process with several click processes.
I think multi_proc_support is for two dpdk processes. (?)
I want to run one DPDK and for example, run 10 click process based on it. fast click can support it?

DPDK is a library, there are no such things as "DPDK processes", there are DPDK applications, like Click and FastClick that uses DPDK.

You can run 10 instances of Click that all use DPDK.
If they're independent (with --file-prefix), you must use different devices in all application. It makes sense with virtual functions/virtualisation for instance.
If they're part of the same logic, then you can run one as primary, and all the others as secondary. Then communicate between the processes with DPDK rings. FastClick supports that (not Click).
