Hi, (Apologies if this is the wrong place to post, but all the links on the MPE page seem to redirect to MPICH.) I am trying to build the MPE profiling libraries to work with MPICH. However, I am getting about a thousand lines of compile error messages, because some MPE routines use K&R-style function declarations, which don't match up with the prototypes in mpi.h 00106 log_mpi_core.c: In function 'MPI_Allgather': 00107 log_mpi_core.c:1550:8: error: argument 'sendbuf' doesn't match prototype 00108 void * sendbuf; 00109 ^ 00110 In file included from log_mpi_core.c:10:0: 00111 /opt/mpich/include/mpi.h:1002:5: error: prototype declaration 00112 int MPI_Allgather(const void *sendbuf, int sendcount, MPI_Datatype sendtype, void *recvbuf, 00113 ^ Before I go and try to fix all these myself, could I ask 1) Has it already been done somewhere? or 2) Has it not been done because there's now something better than MPE for tracing/profiling? To be clear, I'm not interested in profiling MPI itself, but what the program is doing between calls to MPI routines. Thanks, James
