請務(wù)必回答這個(gè)問題 . 提供詳細(xì)信息并分享您的研究！

對不起，我是第一次來這里，只能提問...

使用建議：

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

然后grep mem_heap_B massif.out ... mem_heap_B = 1150976 mem_heap_B = 1150976 ...

這與“top”命令在類似時(shí)刻顯示的內(nèi)容非常不同：

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

來自valgrind的測量單位是什么？

該

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

永遠(yuǎn)不會回答 - 您必須直接將可執(zhí)行文件提供給/ usr / bin / time，如：

/ 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
