[SPDK] Possible to use several hugepage files for NVMe's DMA destination?

Hi,

In general, I'm wondering how to provide the isolation of the hugepage
across
several processes using SPDK in one computer

In my understanding, SPDK's hugepage is initialized by the primary process,
and all will use
*shmid* to be able to find that by several processes. I'm wondering is that
possible that the SPDK is initialized with several *shmid*, such that
several
processes can be isolated?

PS: I'm using the SPDK 18.04.01, does some new version help?

Thanks,
Jing
