+@defgroup SMPI_API SMPI: Simulate real MPI applications
@brief Programming environment for the simulation of MPI applications
This programming environment enables the study of MPI application by
the first time you use MPI code: just use smpicc as a compiler (in
replacement of gcc or your usual compiler), and you're set.
+\note
+ Some configure scripts ("./configure") will test the compiler by
+ compiling some simple example scripts. To make this work, you
+ must set the <b>SMPI_PRETEND_CC</b> environment variable to
+ some arbitrary value, for instance "export SMPI_PRETEND_CC=1"
+
\section SMPI_executing Executing your code on top of the simulator
This is done though the <tt>smpirun</tt> script as follows.
- To register the new version of the algorithm, simply add a line to the corresponding macro in src/smpi/colls/cools.h ( add a "COLL_APPLY(action, COLL_ALLTOALL_SIG, pair)" to the COLL_ALLTOALLS macro ). The algorithm should now be compiled and be selected when using --cfg=smpi/alltoall:pair at runtime.
- - To add a test for the algorithm inside Simgrid's test suite, juste add the new algorithm name in the ALLTOALL_COLL list found inside buildtools/cmake/Tests.cmake . When running ctest, a test for the new algorithm should be generated and executed. If it does not pass, please check your code or contact us.
+ - To add a test for the algorithm inside Simgrid's test suite, juste add the new algorithm name in the ALLTOALL_COLL list found inside teshsuite/smpi/CMakeLists.txt . When running ctest, a test for the new algorithm should be generated and executed. If it does not pass, please check your code or contact us.
- Feel free to push this new algorithm to the SMPI repository using Git.
