pm2 doesn't run with multiple cores

[benag]

I have a multiple cores ubuntu:
Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 4
On-line CPU(s) list: 0-3
Thread(s) per core: 1
Core(s) per socket: 2
Socket(s): 2
....

when running:
pm2 start app.js -i 4

I see only one running,
no error

pm2 version?

pm2 start server.js -i 4 launches 4 processes, it doesn't mean that they won't run in the same core.

Please do: node -e "var os = require('os'); console.log(os.cpus())"

I'm experiencing the same issue. Here is the cpu info:

[ { model: 'Intel(R) Xeon(R) CPU E5-2670 v2 @ 2.50GHz',
speed: 2500,

I see the same behavior with 1.0.2: using -i 0 to get the max or using -i 4 to try 4 does not work for me. I get a single process running in 'fork_mode'

This is how node sees my cpus:

Actually I take that back. I had originally started with "pm2 start app.js" - and though I had stopped via "pm2 stop 0" - I had not actually _deleted_ that original process.

Doing "pm2 delete all" and then "pm2 start app.js -i 0" created a cluster of 8 processes for me.

@benag I bet this is the issue you are having.
