如何使用 hackbench 運行 dohell 指令?

我錯過了關於使用的一點多赫爾命令。請指出。

anisha@linux-dopx:~/Desktop/RealTime/downloadedPages> /usr/xenomai/bin/dohell -b ~/Desktop/RealTime/downloadedPages/hackbench
/usr/xenomai/bin/dohell [ -b path ] [ -s server ] [ -p port ] [ -m mntpoint ] [ -l path | seconds ]

Generate load, using an assorted set of commands and optionnaly:
[B]- hackbench if the path to the hackbench binary is specified with -b;[/B]
- nc to send TCP data to "server" port "port" if -s is specified (if -p
is not specified, the port 9, aka discard is used);
- dd to write data under "mntpoint" if -m is specified.

during the runtime of the LTP test if the path to the LTP installation
directory is specifed with -l or during "seconds" seconds.

黑客台類型:

anisha@linux-dopx:~/Desktop/RealTime/downloadedPages> file hackbench
hackbench: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.4, not stripped

dohell分別嘗試使用hackbenchseconds參數如下(並且它工作正常):

linux-dopx:~ # /usr/xenomai/bin/dohell -b
"/home/anisha/Desktop/RealTime/downloadedPages/hackbench -pipe 100
process 100 seconds" 2
Running with 100*40 (== 4000) tasks.

/usr/xenomai/bin/dohell: line 94: 17276 Terminated              while :; do
   $hackbench 1;
done
/usr/xenomai/bin/dohell: line 94: 17277 Terminated              while :; do
   cat /proc/interrupts;
done > /dev/null 2>&1
/usr/xenomai/bin/dohell: line 94: 17279 Terminated              while :; do
   ps w;
done > /dev/null 2>&1
/usr/xenomai/bin/dohell: line 94: 17280 Terminated              dd

/usr/xenomai/bin/dohell: line 94: 17281 Terminated              while :; do
   ls -lR / > /dev/null 2>&1;
done
Killed

然後我嘗試了同樣的操作,xeno-test如下所示:

/usr/xenomai/bin/xeno-test -l "dohell -b
"/home/anisha/Desktop/RealTime/downloadedPages/hackbench -pipe 100
process 100 seconds" 2"
and
/usr/xenomai/bin/xeno-test -l "dohell -b
/home/anisha/Desktop/RealTime/downloadedPages/hackbench -pipe 100
process 100 seconds 2"
and
/usr/xenomai/bin/xeno-test -l dohell -b
/home/anisha/Desktop/RealTime/downloadedPages/hackbench -pipe 100
process 100 seconds 2
and also,
/usr/xenomai/bin/xeno-test -l "dohell -b
/home/anisha/Desktop/RealTime/downloadedPages/hackbench -pipe 100
process 100" -T 2
and
/usr/xenomai/bin/xeno-test -l "dohell -b
/home/anisha/Desktop/RealTime/downloadedPages/hackbench -pipe 100
process 100" -t 2

所有這些都產生了相同的最終結果:
運行這個的方法是什麼?請幫忙。

答案1

最後一個參數是強制性的。

如果您有使用交換器的 LTP 安裝,請傳遞一個路徑-l,或傳遞運行的秒數。

(dohell是一個普通 shell 腳本,你可以看看它來檢查它是如何工作的。

答案2

當然指定持續時間是必須的,但是

xeno-test -l "dohell -b /home/anisha/Desktop/RealTime/downloadedPages/hackbench -pipe 100  process 100 14400"

仍然沒有給出所需的輸出。問題出在 hackbench 指定的「參數」。
dohell命令(帶有 hackbench 參數)(單獨)運行良好,但與xeno-test.

我刪除了 hackbench 的參數 ( "-pipe 100 process 100"),然後它開始使用xeno-test.

以下作品:
xeno-test -l "dohell -b /home/anisha/Desktop/RealTime/downloadedPages/hackbench 14400"
