See License.txt for licensing information.
See README.osx, README.linux and soon README.win for MPI and cmake installation instructions
See README.ndiff for instructions to install ndiff. A copy of the ndiff tar file is also included as a backup to getting it from the ndiff website. -- check that the ndiff executable is in the path with 'which ndiff'
Numdiff is an alternative program that performs the same function. It is at https://www.nongnu.org/numdiff/
Valgrind needs to be installed for the last example.
Requires CMake, CTest, and ndiff
Change into the Listing1 directory
Run the test with
cd Listing1
mkdir build
cd build
cmake ..
make
make test
or
ctest
To see the output when the test fails:
ctest --output-on-failure
If the test does not run properly, try invoking it manually with
sh mympiapp.ctest
You should get some results like the following.
Running tests...
Test project /Users/brobey/Programs/RunDiff
Start 1: mpitest.ctest
1/1 Test #1: mpitest.ctest .................... Passed 30.24 sec
100% tests passed, 0 tests failed out of 1
Total Test time (real) = 30.24 sec
This test is based on the sleep function and timers, so it may or may not pass. Test results are in Testing/Temporary/*
Requires CMake and CTest
Change into the Listing2 directory
Run the test with
cd Listing2
mkdir build
cd build
cmake ..
make
ctest -R commit
or
make commit_tests
Requires Valgrind and a C99 standard C compiler
Change into the Listing3 directory
Run the valgrind test with
cd Listing3
make
valgrind --leak-check=full ./test 2
