Sorry, I am first time here and can only ask questions ...

valgrind --tool=massif --pages-as-heap=yes --massif-out-file=massif.out ./test.sh; grep mem_heap_B massif.out | sed -e 's/mem_heap_B=(.*)/\1/' | sort -g | tail -n 1

then grep mem_heap_B massif.out ... mem_heap_B=1150976 mem_heap_B=1150976 ...

this is very different from what "top" command shows at similar moment  :

14673 gu27mox 20 0 3280404 468380 19176 R 100.0 2.9 6:08.84 pwanew_3pic_com

what are measured units from valgrind ??

The

/usr/bin/time -v ./test.sh

never answered - you must directly feed executable to /usr/bin/time like:

/usr/bin/time -v pwanew_3pic_compass_2008florian3_dfunc.static card_0.100-0.141_31212_resubmit1.dat_1.140_1.180 1.140 1.180 31212
