StressSuite
===========
General Description
-------------------
StressSuite is a tool that provides a collection of stress suites. Thoses
suites themselves provides stress tests. Thoses stress tests are intented
to stress something specific.
Stress suites
-------------
There is already two stress suites in stresssuite :
- For the filesystem named 'Files',
- For the CPU named 'CPU'
Tests for 'Files' testsuite are :
- 000 : 'Directory creation' : Creates directories in one single directory
- 001 : 'Files creation' : Creates files in one single directory
- 002 : 'Zero filed files creation' : Creates zero filed files (size vary and
buffer size is an option)
Tests for 'CPU' testsuite are :
- 000 : 'Cpu encode stress' : Stress the cpu(s) with base64 and rot13 functions
- 001 : 'Cpu hash tests' : Stress the cpu(s) with sha512 and md5 functions

stresssuite
SYNOPSIS
stresssuite [OPTIONS]...
DESCRIPTION
Runs stress testsuites
OPTIONS
When two exclusive options are specified (like -o and -m for
instance), the selected one is the last specified on the command
line.
-h, --help
Show this help
-d, --debug
More verbose
-l, --list
Show all tests with their contexts. When this option is used, it
will prevail over -o or -m options
-o, --once
Runs all tests only once
-n, --no-stats
Does not print any stats at the end of the tests
-c, --cumulative
Prints stats in a cumulative manner
--gnuplot=PATH
Export results (stats) to gnuplot formated files. PATH indicates
the path where files might be created
-m NUM, --multiple=NUM
Tell to run the tests exactly NUM times
--process=NUM
Tell the numbers of process for one test (one by default)
--buffer-size=NUM
Tells the buffer size to use when creating files (512 by default)
-s, --step=NUM
Used in the vary function to step the algorithm (generally it
is used to multiply the number of tests but it depends on the
test itself to do what it wants with this value)
-p PATH, --path=PATH
Tells which path to use to run stresssuite program.
'/tmp' by default
--testname='NAME'
Selects one test specificaly
--testsuite='NAME'
Selects one entire test suite specificaly. If --testname is
specified at the same time then --testsuite option is ignored
NAME must be a name as listed by -l or --list option
EXAMPLES
./stresssuite.py -d --path=/home/dup/tmp -m 10
./stresssuite.py -d --path=/home/dup/tmp/stressfs --testsuite='Files' \\
-m 4 -s 10 --process=5
./stresssuite.py --list
Constraints
-----------
Should not work with python versions under 2.5 (hashlib and multiprocessing
dependencies)
