linux - How to befriend real-time processes and OOM killer? - 


$ mlockall schedtool -r -p 4 -e ionice -c1 mplayer -really-quiet whatever.ogg $ mempig killed

mplayer

  • is running realtime scheduling priority
  • is running realtime io priority
  • have it's pages locked in memory

but still "chops" when start oom-killer bait.

what more can done make real-time processes real-time when oom? (expect of "vm.overcommit_memory=2", of course)

this old question, i'm not going go on , on, but, /proc/pid/oom_adj , /proc/pid/oom_score

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
