Hello,
I have a machine on which there is a bit non common setup: I have only
"node1" (no node0) under /sys/devices/system/node:
ls /sys/devices/system/node/
...
node1
...
I have 2 sockets on this machines, and 16 cores:
./tools/cpu_layout.py
============================================================
Core and Socket Information (as reported by '/proc/cpuinfo')
============================================================
cores = [0, 1, 2, 3]
sockets = [0, 1]
Socket 0 Socket 1
-------- --------
Core 0 [0, 8] [4, 12]
Core 1 [1, 9] [5, 13]
Core 2 [2, 10] [6, 14]
Core 3 [3, 11] [7, 15]
What should be the "-c" and "-n" EAL paramaters that I should use ? I
made several trials but
none of them succeeded, applications cannot start.
Please let me know if anything else is needed.
Regards,
Kevin
