Memory sharing between two primary processes

[Kiran Khatke]

Hi,


Per DPDK Multiprocess, we know that, it is possible to share
memory(hugepages) between a primary and secondary Process.  Primary process
allocates the memory and that is accessible by the secondary (both are
using same  "--file-prefix=" parameter).



There is a need in our application, to have two primary processes (started
with different file-prefix) and would like to know the options - To share
memory (hugepage) between two primaries and which can give us better
throughputs.



During exploration, got to know about memif PMD, which allows for DPDK and
any other client using memif (DPDK, libmemif) to communicate over shared
memory.

Do you have any comments about memif performance ? Are there better options
over memif to share memory between two primaries ?


Thanks ,

Kiran
