[mpich-discuss] Problems with Pcontrol and MPE2 -- fixed, please accept this patch

[Anthony Chan]

Hi Brian,

Can you try log_mpi_core.c again ?

https://svn.mcs.anl.gov/repos/mpi/mpich2/trunk/src/mpe2/src/wrappers/src/log_mpi_core.c

You may also need the update in slog2sdk, i.e. jumpshot and clog2TOslog2 code.

https://svn.mcs.anl.gov/repos/mpi/mpich2/trunk/src/mpe2/src/slog2sdk/lib/jumpshot.jar
https://svn.mcs.anl.gov/repos/mpi/mpich2/trunk/src/mpe2/src/slog2sdk/lib/clog2TOslog2.jar
