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) tx_h-yamashita@R730n10:~$ sudo numastat -p spp_ [sudo] password for tx_h-yamashita: Per-node process memory usage (in MBs) PID Node 0 Node 1 Total ------------------- --------------- --------------- --------------- 36244 (sudo) 1.23 6.30 7.53 36245 (spp_primary) 8196.33 8203.80 16400.13 36255 (sudo) 0.20 9.52 9.73 ------------------- --------------- --------------- --------------- Total 8197.76 8219.62 16417.38 tx_h-yamashita@R730n10:~$ tx_h-yamashita@R730n10:~$ tx_h-yamashita@R730n10:~$ tx_h-yamashita@R730n10:~$ tx_h-yamashita@R730n10:~$ tx_h-yamashita@R730n10:~$ tx_h-yamashita@R730n10:~$ grep HugePages_ /proc/meminfo HugePages_Total: 16 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 tx_h-yamashita@R730n10:~$ sudo numastat -p spp_ Per-node process memory usage (in MBs) PID Node 0 Node 1 Total ------------------- --------------- --------------- --------------- 36244 (sudo) 1.23 6.30 7.53 36245 (spp_primary) 8196.33 8203.80 16400.13 36261 (sudo) 0.20 9.52 9.71 36262 (spp_nfv) 8206.14 8194.36 16400.50 36267 (sudo) 0.33 7.02 7.34 ------------------- --------------- --------------- --------------- Total 16404.22 16420.99 32825.21 tx_h-yamashita@R730n10:~$ tx_h-yamashita@R730n10:~$ tx_h-yamashita@R730n10:~$ tx_h-yamashita@R730n10:~$ tx_h-yamashita@R730n10:~$ tx_h-yamashita@R730n10:~$ tx_h-yamashita@R730n10:~$ grep HugePages_ /proc/meminfo HugePages_Total: 16 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 tx_h-yamashita@R730n10:~$ sudo numastat -p spp_ Per-node process memory usage (in MBs) PID Node 0 Node 1 Total ------------------- --------------- --------------- --------------- 36244 (sudo) 1.23 6.30 7.53 36245 (spp_primary) 8196.33 8203.80 16400.13 36261 (sudo) 0.20 9.52 9.71 36262 (spp_nfv) 8206.14 8194.36 16400.50 36273 (sudo) 0.20 9.68 9.89 36274 (spp_nfv) 8206.15 8194.17 16400.32 36279 (sudo) 1.23 6.29 7.52 ------------------- --------------- --------------- --------------- Total 24611.48 24624.12 49235.60 tx_h-yamashita@R730n10:~$ BR, Hideyuki Yamashita --=20 You are receiving this mail because: You are on the CC list for the bug.=
