* Error: cannot allocate vector of size {{{ You have, presumably, a 32-bit computer with a 4GB-per-process memory limit. You have hit it (you get less than 4Gb as the OS services need some and there is some fragmentation). The last failed allocation may be small, as you see, if you are allocating lots of smallish pieces. The only way to overcome that is to use a 64-bit OS and version of R. }}} * run in kerrighed, meet out of memory error message -> Guess that Kerrigthed MM module's scheduler not support R's operation * Enable Kerrighed USE_REMOTE_MEMORY {{{ $ R # justRMA original limit: 145 CELs setwd("/home/mnt/chris_rmpi/cel_data_mixed") rm(list=ls()) dir() library(affy) CELNames<-dir(".", "[.]CEL") CELNames<-CELNames[1:305] data <- justRMA(filenames=CELNames) $ dmesg init.orig invoked oom-killer: gfp_mask=0x201d2, order=0, oomkilladj=0 [] out_of_memory+0x7f/0x19c [] __alloc_pages+0x208/0x292 [] __do_page_cache_readahead+0xcf/0x1fc [] io_schedule+0x22/0x2c [] __wait_on_bit_lock+0x4b/0x52 [] __lock_page+0x64/0x6b [] do_page_cache_readahead+0x41/0x4a [] filemap_nopage+0x159/0x304 [] __handle_mm_fault+0x170/0x85d [] common_interrupt+0x23/0x28 [] do_page_fault+0x231/0x543 [] read_tsc+0x6/0x7 [] do_page_fault+0x0/0x543 [] error_code+0x7c/0x84 [] tipc_link_send_long_buf+0x2b/0x1eb ======================= 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 Normal per-cpu: CPU 0: Hot: hi: 186, btch: 31 usd: 57 Cold: hi: 62, btch: 15 usd: 61 CPU 1: Hot: hi: 186, btch: 31 usd: 44 Cold: hi: 62, btch: 15 usd: 50 CPU 2: Hot: hi: 186, btch: 31 usd: 156 Cold: hi: 62, btch: 15 usd: 14 CPU 3: Hot: hi: 186, btch: 31 usd: 163 Cold: hi: 62, btch: 15 usd: 25 HighMem per-cpu: CPU 0: Hot: hi: 186, btch: 31 usd: 30 Cold: hi: 62, btch: 15 usd: 14 CPU 1: Hot: hi: 186, btch: 31 usd: 9 Cold: hi: 62, btch: 15 usd: 17 CPU 2: Hot: hi: 186, btch: 31 usd: 29 Cold: hi: 62, btch: 15 usd: 43 CPU 3: Hot: hi: 186, btch: 31 usd: 149 Cold: hi: 62, btch: 15 usd: 56 Active:493418 inactive:306 dirty:0 writeback:0 unstable:0 free:12001 slab:4191 mapped:2 pagetables:576 DMA free:8032kB min:68kB low:84kB high:100kB active:2748kB inactive:0kB present:16256kB pages_scanned:13504 all_unreclaimable? yes lowmem_reserve[]: 0 873 1991 Normal free:39508kB min:3744kB low:4680kB high:5616kB active:819348kB inactive:748kB present:894080kB pages_scanned:1380165 all_unreclaimable? yes lowmem_reserve[]: 0 0 8950 HighMem free:464kB min:512kB low:1712kB high:2912kB active:1151464kB inactive:476kB present:1145604kB pages_scanned:3364854 all_unreclaimable? yes lowmem_reserve[]: 0 0 0 DMA: 0*4kB 0*8kB 0*16kB 1*32kB 1*64kB 0*128kB 1*256kB 1*512kB 1*1024kB 1*2048kB 1*4096kB = 8032kB Normal: 1*4kB 0*8kB 1*16kB 0*32kB 1*64kB 0*128kB 0*256kB 1*512kB 0*1024kB 15*2048kB 2*4096kB = 39508kB HighMem: 0*4kB 2*8kB 2*16kB 1*32kB 0*64kB 1*128kB 1*256kB 0*512kB 0*1024kB 0*2048kB 0*4096kB = 464kB Swap cache: add 0, delete 0, find 0/0, race 0+0 Free swap = 0kB Total swap = 0kB Free swap: 0kB 518032 pages of RAM 288656 pages of HIGHMEM 5714 reserved pages 173 pages shared 0 pages swap cached 0 pages dirty 0 pages writeback 2 pages mapped 4191 pages slab 576 pages pagetables }}} * Don't enable Kerrighed USE_REMOTE_MEMORY {{{ $ dmesg R invoked oom-killer: gfp_mask=0x201d2, order=0, oomkilladj=0 Out of memory: kill process 38507 (bash) score 15539 or a child Killed process 38515 (R) }}} * Use swap to slove this problem or wait kerrighed memory stable functions (If your clinet' fs is nfs, must use client's physical disk to be swap parition) {{{ $ dd if=/dev/zero of=swap.img bs=1M count=8000 $ mkswap swap.img $ swapon swap.img }}} [[BR]] * Kerrighed's DSM can't support R.
