Feel free to post your questions there. 5 6 ----------------------------------- COMPILATION ----------------------------------- 7 We are doing our best to ensure the test case will be very portable. 8 Please report any problems on the forum (see on top of this file) 9 10 11 * Flags 12 You may want to add -DVERBOSE=2 to have verbose tests, 13 or -DVERBOSE=0 to have silent tests (for batchs for example). 14 15 You may add -DWITHOUT_XOPEN to disable the XSI features 16 from the tests. Some of the tests won't work with this option. 17 18 You may want to add -DSCALABILITY_FACTOR=X, where X is an integer, 19 to change the stress programs load (default is 1). 20 21 22 * Commands 23 Compilation under linux: 24 gcc -o <bin> -lpthread <source> 25 where <bin> is the executable you want to build and <source> is the source file. 26 27 Compilation under AIX5L 28 cc -o <bin> -lpthread <source> 29 same comment as above 30 31 Compilation under Solaris 9 (gcc: http://www.sunfreeware.com) 32 gcc -std=gnu99 -lpthread -lrt -o <bin> <source> 33 same comment as above. 34 Note: the -lrt is necessary for test cases using semaphore feature. 35 36 * Execution 37 38 Please consider the following: 39 -> I am sizing the tests to fit on a bi-xeon IA32 machine, with 2GB RAM. 40 You can change the SCALABILITY_FACTOR value to 2 or 3 to be more 41 resources consuming on a bigger system. This will create more threads, 42 etc... according to each case. 43 44 -> Stress tests will run until they are killed with SIGUSR1 (or they 45 fail). Currently, I do 46 $> ./stress & 47 and then after a while 48 $> kill -USR1 <pid> 49 or 50 $> for PR in `ps o pid --no-headers -Cstress`; \ 51 do echo Sending SIGUSR1 to pid $PR...; \ 52 kill -USR1 $PR; \ 53 done; 54 Some cases will keep on executing ~ 1 minute after they receive the 55 signal; it is normal (time for stopping all threads). 56 57
