\section SMPI_what What can run within SMPI?
You can run unmodified MPI applications (both C and Fortran) within
-SMPI, provided that (1) you only use MPI calls that we implemented in
-MPI and (2) you don't use any globals in your application.
+SMPI, provided that you only use MPI calls that we implemented in
+MPI. Global variables should be handled correctly on Linux systems.
\subsection SMPI_what_coverage MPI coverage of SMPI
- 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.
