Hi, While testing, Santwana has encountered that Hackbench invoked oom-killer, while running ltp runall. It has been recently ported to LTP from the Original program available at Red Hat site, and, has undergone few changes satisfying to LTP´s needs. The program can be found here:
http://ltp.cvs.sourceforge.net/ltp/ltp/testcases/kernel/sched/cfs-scheduler/hackbench.c, and the ways it is invoked is: hackbench01 hackbench 150 process 1000 hackbench02 hackbench 20 thread 1000 Jin/Yamato, Have you encountered oom-killer while executing Hackbench ? I doubt that it has got to do with the way we invoke hackbench01 test. We can instead change this to: hackbench01 hackbench 20 process 1000, from hackbench01 hackbench 150 process 1000, and see whether this can solve this problem. Santwana, Can you see whether this works out ? Following are the various details of the error encountered: ---uname output--- Linux 2.6.16.60-0.21-xenpae #1 SMP Tue May 6 12:41:02 UTC 2008 i686 i686 i386 GNU/Linux, ---Steps to Reproduce--- Run ltp by issuing: nohup ./runltp -p -q -l [logfile name] -o [outputfile name] -t 24h & oom-killer is noticed in dmesg as well as /var/log/messages. hackbench invoked oom-killer: gfp_mask=0x4d0, order=0, oomkilladj=0 [<c01584f5>] oom_kill_process+0x105/0x110 [<c0158890>] out_of_memory+0x100/0x160 [<c015a8f6>] __alloc_pages+0x316/0x360 [<c012abe5>] do_softirq+0x85/0x90 [<c017a067>] cache_alloc_refill+0x337/0x5c0 [<c0105c81>] hypervisor_callback+0x3d/0x48 [<c0179d1b>] kmem_cache_alloc+0x8b/0xa0 [<c02a1bd3>] __alloc_skb+0x33/0x110 [<c029e14d>] sock_alloc_send_skb+0x17d/0x1f0 [<c02a2b77>] memcpy_fromiovec+0x37/0x50 [<c030a68e>] unix_stream_sendmsg+0x21e/0x3c0 [<c029ab53>] do_sock_write+0xa3/0xd0 [<c029bc95>] sock_aio_write+0x75/0x80 [<c01097a7>] profile_pc+0x37/0x80 [<c017dc34>] do_sync_write+0xc4/0x100 [<c013b240>] autoremove_wake_function+0x0/0x40 [<c012aac6>] __do_softirq+0x86/0x120 [<c017e7da>] vfs_write+0x16a/0x1a0 [<c017ef53>] sys_write+0x53/0x90 [<c0105aad>] syscall_call+0x7/0xb Mem-info: DMA per-cpu: CPU 0: Hot: hi: 0, btch: 1 usd: 0 Cold: hi: 0, btch: 1 usd: 0 CPU 1: Hot: hi: 0, btch: 1 usd: 0 Cold: hi: 0, btch: 1 usd: 0 CPU 2: Hot: hi: 0, btch: 1 usd: 0 Cold: hi: 0, btch: 1 usd: 0 CPU 3: Hot: hi: 0, btch: 1 usd: 0 Cold: hi: 0, btch: 1 usd: 0 CPU 4: Hot: hi: 0, btch: 1 usd: 0 Cold: hi: 0, btch: 1 usd: 0 CPU 5: Hot: hi: 0, btch: 1 usd: 0 Cold: hi: 0, btch: 1 usd: 0 CPU 6: Hot: hi: 0, btch: 1 usd: 0 Cold: hi: 0, btch: 1 usd: 0 CPU 7: Hot: hi: 0, btch: 1 usd: 0 Cold: hi: 0, btch: 1 usd: 0 Normal per-cpu: CPU 0: Hot: hi: 186, btch: 31 usd: 34 Cold: hi: 62, btch: 15 usd: 55 CPU 1: Hot: hi: 186, btch: 31 usd: 13 Cold: hi: 62, btch: 15 usd: 61 CPU 2: Hot: hi: 186, btch: 31 usd: 151 Cold: hi: 62, btch: 15 usd: 56 CPU 3: Hot: hi: 186, btch: 31 usd: 44 Cold: hi: 62, btch: 15 usd: 50 CPU 4: Hot: hi: 186, btch: 31 usd: 3 Cold: hi: 62, btch: 15 usd: 60 CPU 5: Hot: hi: 186, btch: 31 usd: 59 Cold: hi: 62, btch: 15 usd: 53 CPU 6: Hot: hi: 186, btch: 31 usd: 3 Cold: hi: 62, btch: 15 usd: 53 CPU 7: Hot: hi: 186, btch: 31 usd: 31 Cold: hi: 62, btch: 15 usd: 61 HighMem per-cpu: CPU 0: Hot: hi: 186, btch: 31 usd: 30 Cold: hi: 62, btch: 15 usd: 0 CPU 1: Hot: hi: 186, btch: 31 usd: 115 Cold: hi: 62, btch: 15 usd: 7 CPU 2: Hot: hi: 186, btch: 31 usd: 116 Cold: hi: 62, btch: 15 usd: 9 CPU 3: Hot: hi: 186, btch: 31 usd: 164 Cold: hi: 62, btch: 15 usd: 11 CPU 4: Hot: hi: 186, btch: 31 usd: 177 Cold: hi: 62, btch: 15 usd: 8 CPU 5: Hot: hi: 186, btch: 31 usd: 180 Cold: hi: 62, btch: 15 usd: 9 CPU 6: Hot: hi: 186, btch: 31 usd: 146 Cold: hi: 62, btch: 15 usd: 38 CPU 7: Hot: hi: 186, btch: 31 usd: 150 Cold: hi: 62, btch: 15 usd: 0 Free pages: 8003600kB (7997324kB HighMem) Active:74821 inactive:3038 dirty:19 writeback:0 unstable:0 free:2000900 slab:118580 mapped:872 pagetables:24268 DMA free:2912kB min:72kB low:88kB high:108kB active:0kB inactive:0kB present:16384kB pages_scanned:0 all_unreclaimable? yes lowmem_reserve[]: 0 0 711 8835 Normal free:3364kB min:3376kB low:4220kB high:5064kB active:116kB inactive:116kB present:729080kB pages_scanned:0 all_unreclaimable? no lowmem_reserve[]: 0 0 0 64990 HighMem free:7997324kB min:512kB low:10140kB high:19772kB active:299168kB inactive:12036kB present:8318816kB pages_scanned:0 all_unreclaimable? no lowmem_reserve[]: 0 0 0 0 DMA: 0*4kB 0*8kB 0*16kB 1*32kB 1*64kB 0*128kB 1*256kB 1*512kB 0*1024kB 1*2048kB 0*4096kB = 2912kB Normal: 15*4kB 1*8kB 0*16kB 3*32kB 0*64kB 1*128kB 0*256kB 0*512kB 1*1024kB 1*2048kB 0*4096kB = 3364kB HighMem: 95*4kB 2*8kB 2*16kB 1*32kB 1*64kB 87*128kB 754*256kB 598*512kB 345*1024kB 245*2048kB 1619*4096kB = 7997324kB Swap cache: add 216841, delete 215153, find 407/493, race 0+0 Free swap = 4163536kB Total swap = 4200988kB Free swap: 4163536kB 2266070 pages of RAM 2079704 pages of HIGHMEM 38075 reserved pages 305938 pages shared 1690 pages swap cached 19 pages dirty 0 pages writeback 872 pages mapped 118533 pages slab 24268 pages pagetables Regards-- Subrata ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Ltp-list mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/ltp-list
