I tried this in my setup and below is my configuration :

I have 4 cpus with 1 core per socket.  1 numa node.

*CPU(s):                4*
*On-line CPU(s) list:   0-3*
*Thread(s) per core:    1*
*Core(s) per socket:    1*
*Socket(s):             4*
*NUMA node(s):          1*

*Hugepage information:*

HugePages_Total:    3824
HugePages_Free:     3312
HugePages_Rsvd:        0
HugePages_Surp:        0
Hugepagesize:       2048 kB

I start nvmf_tgt using the following options :

*-r /var/run/spdk.sock -m 0xc -s 1024*

*Since I am using -m 0xc, the reactors starts on core 2 and core 3.  Here
is the output :*

*[ DPDK EAL parameters: nvmf -c 0xc -m 1024 --file-prefix=spdk_pid14924 ]*
*EAL: Detected 4 lcore(s)*
*EAL: No free hugepages reported in hugepages-1048576kB*
*EAL: Probing VFIO support...*
*app.c: 377:spdk_app_start: *NOTICE*: Total cores available: 2*

*reactor.c: 426:_spdk_reactor_run: *NOTICE*: Reactor started on core 3 on
socket 0*
*reactor.c: 426:_spdk_reactor_run: *NOTICE*: Reactor started on core 2 on
socket 0*

I run the initiator and force it to run on core 0x1.

The host that I am doing 'ssh' to gets disconnected.  Here is the output
when the host gets disconnected :

Has anyone tried this in your setup and if so, any help is highly
appreciated.
