bench_run
Launch benchmark tests
Calling Sequence
bench_run() bench_run(module[,test_name[,options]])
Arguments
- module
a vector of string. It can be the name of a module or the absolute path of a toolbox.
- test_name
a vector of string
- options
a vector of string
list : list of the benchmark tests available in a module
help : displays some examples of use in the Scilab console
nb_run=value : repeat the benchmark test value times
Description
Search for .tst files in benchmark test library execute them, and display a report about execution time. The .tst files are searched in directories SCI+"/modules/*/tests/benchmark".
Special tags may be inserted in the .tst file, which help to control the processing of the corresponding test. These tags are expected to be found in Scilab comments.
These are the available tags :
<-- BENCH NB RUN : 10 --> This test will be repeated 10 times.
<-- BENCH START --> <-- BENCH END --> The interesting part of the benchmark must be enclosed by these tags.
Examples
Some simple examples of invocation of bench_run
// Launch all tests bench_run(); bench_run([]); bench_run([],[]); // Test one or several module bench_run('core'); bench_run('core',[]); bench_run(['core','string']); // Launch one or several test in a specified module bench_run('core',['trycatch','opcode']); // With options bench_run([],[],'list'); bench_run([],[],'help'); bench_run([],[],'nb_run=2000');
An example of a benchmark file. This file corresponds to the file SCI/modules/linear_algebra/tests/benchmarks/bench_chol.tst.
