Feel free to post your questions there. 5 6 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 want to add -DSCALABILITY_FACTOR=X, where X is an integer, 16 to change the stress programs load (default is 1). 17 18 19 * Commands 20 Compilation under linux: 21 gcc -o <bin> -lpthread <source> 22 where <bin> is the executable you want to build and <source> is the source file. 23 24 Compilation under AIX5L 25 cc -o <bin> -lpthread <source> 26 same comment as above 27 28 Compilation under Solaris 9 (gcc: http://www.sunfreeware.com) 29 gcc -std=gnu99 -lpthread -lrt -o <bin> <source> 30 same comment as above. 31 Note: the -lrt is necessary for test cases using semaphore feature. 32 33 * Execution 34 35 Please consider the following: 36 -> I am sizing the tests to fit on a bi-xeon IA32 machine, with 2GB RAM. 37 You can change the SCALABILITY_FACTOR value to 2 or 3 to be more 38 resources consuming on a bigger system. This will create more threads, 39 etc... according to each case. 40 41 -> Stress tests will run until they are killed with SIGUSR1 (or they 42 fail). Currently, I do 43 $> ./stress & 44 and then after a while 45 $> kill -USR1 <pid> 46 or 47 $> for PR in `ps o pid --no-headers -Cstress`; \ 48 do echo Sending SIGUSR1 to pid $PR...; \ 49 kill -USR1 $PR; \ 50 done; 51 Some cases will keep on executing ~ 1 minute after they receive the 52 signal; it is normal (time for stopping all threads). 53 54
