<pre><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;">Hello @ all,</div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;"><br></div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;">my question is concerning the PMPI specification. I hope the list is the correct place to ask.</div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;"><br></div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;">I want to write a complete wrapper for MPI. That is every define, typedef and function will be wrapped and might be completely changed. Currently I prefixed everything with AMPI_ such that no name clashes exist. But the user would need to rename every occurrence of MPI_ with AMPI_</div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;"><br></div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;">I would now like to use the PMPI definition of MPI to define my wrappers as the MPI version which then use the PMPI definitions. Unfortunately I could not find tutorials for a complete wrapper.</div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;"><br></div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;">As an example take MPI_COMM_WORLD. I made a grep on the openmpi installation on my linux machine for PMPI_COMM_WORLD but the result was empty. The definition of MPI_COMM_WORLD was </div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;">#define MPI_COMM_WORLD OMPI_PREDEFINED_GLOBAL( MPI_Comm, ompi_mpi_comm_world)</div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;">without any chance to switch to PMPI_COMM_WORLD as a predefined macro.</div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;"><br></div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;">I also checked the newest source tarball of openmpi and I could not find anything for PMPI_COMM_WORLD there.</div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;"><br></div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;">In the mpi 3.0 standard on page 555 in section 14.2.1 the requirements are just listed for functions. Was the definition of the PMPI_ supplements for defines, types etc. never discussed?</div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;"><br></div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;">I would have expected, that I can just include a pmpi.h and then I would have all the PMPI_ symbols without the MPI symbols available.</div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;"><br></div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;">Do you know of any way I could make my idea work?</div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;"><br></div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;">Cheers</div><div style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;"><br></div><pre><span style="color: rgb(0, 0, 0); font-family: Cantarell; white-space: normal;">Max</span></pre><pre><br></pre><pre>-- <br></pre>Max Sagebaum
