| ----------------------------------- COMPILATION ----------------------------------- |
| We are doing our best to ensure the test case will be very portable. |
| Please report any problems on the forum (see on top of this file) |
| |
| |
| * Flags |
| You may want to add -DVERBOSE=2 to have verbose tests, |
| or -DVERBOSE=0 to have silent tests (for batchs for example). |
| |
| You may want to add -DSCALABILITY_FACTOR=X, where X is an integer, |
| to change the stress programs load (default is 1). |
| |
| You may want to add -DPLOT_OUTPUT if you want data for plotting. |
| |
| * Commands |
| Compilation under linux: |
| gcc -o <bin> -lpthread -lm -lrt <source> |
| where <bin> is the executable you want to build and <source> is the source file. |
| |
| * Execution |
| This case will possiblly run for half an hour. |
| If you want diagrams showing the result: |
| a. Add -DPLOT_OUTPUT flags when compiling |
| b. ./s-c > data |
| c. ./do-plot data |
| This script will use gnuplot to create a png file named scalable.png. |
| |
| (If your gnuplot does not support png terminal, just remove |
| set term png |
| set output "scalable.png" |
| from the do-plot script). |
| |
| Stress tests will run until they are killed with SIGUSR1 (or they |
| fail). Currently, I do |
| $> ./stress & |
| and then after a while |
| $> kill -USR1 <pid> |
| or |
| $> for PR in `ps o pid --no-headers -Cstress`; \ |
| do echo Sending SIGUSR1 to pid $PR...; \ |
| kill -USR1 $PR; \ |
| done; |
| Some cases will keep on executing ~ 1 minute after they receive the |
| signal; it is normal (time for stopping all threads). |
