--- Comment #21 from Hideyuki Yamashita (yamashita.hideyuki@ntt-tx.co.jp) ---
Hello Vipin,

I understand that this ticket is related with "hugepage usage"
as ticket title tells.

I understand that hugepage usage does NOT increase
regardless of number of secondary process.

The following is the result
- hugepage in system is 16G
- primary uses 8G in node0 and 8G in node1
- two secondary processes can start without increasing hugapage usage

What is the problem?

tx_h-yamashita@R730n10:~$ grep HugePages_ /proc/meminfo
HugePages_Total: 16
HugePages_Free: 0
HugePages_Rsvd: 0
HugePages_Surp: 0
tx_h-yamashita@R730n10:~$ numastat -p spp_

Per-node process memory usage (in MBs)
