7We are doing our best to ensure the test case will be very portable.
8Please report any problems on the forum (see on top of this file)

10
11 * Flags
12You may want to add -DVERBOSE=2 to have verbose tests,
13or -DVERBOSE=0 to have silent tests (for batchs for example).
14
15You may add -DWITHOUT_XOPEN to disable the XSI features
16from the tests. Some of the tests won't work with this option.
17
18You may want to add -DSCALABILITY_FACTOR=X, where X is an integer,
19to change the stress programs load (default is 1).

22 * Commands
23Compilation under linux:
24gcc -o <bin> -lpthread <source>
25   where <bin> is the executable you want to build and <source> is the source file.
26
27Compilation under AIX5L
28cc -o <bin> -lpthread <source>
29  same comment as above
30
31Compilation under Solaris 9 (gcc: http://www.sunfreeware.com)
32gcc -std=gnu99 -lpthread -lrt  -o <bin> <source>
33  same comment as above.
34  Note: the -lrt is necessary for test cases using semaphore feature.

36 * Execution
37
38Please consider the following:
39-> I am sizing the tests to fit on a bi-xeon IA32 machine, with 2GB RAM.
40You can change the SCALABILITY_FACTOR value to 2 or 3 to be more
41resources consuming on a bigger system. This will create more threads,
42etc... according to each case.
43
44-> Stress tests will run until they are killed with SIGUSR1 (or they
45fail). Currently, I do
46$> ./stress &
47and then after a while
48$> kill -USR1 <pid>
49or
50$> for PR in `ps o pid --no-headers -Cstress`; \
51   do echo Sending SIGUSR1 to pid $PR...; \
52       kill -USR1 $PR; \
53   done;
54Some cases will keep on executing ~ 1 minute after they receive the
55signal; it is normal (time for stopping all threads).
