[Trilinos-Users] Ctest Pliris error

[Joe Kotulski]

                Jason,

                The variables MPI_ANY_SOURCE and MPI_ANY_TAG used in 
this receive
                are MPI variables defined in mpi.h and are not set in 
the code.  The only possibility
                I see for this happening is for some reason these are 
being overwritten in memory and are no longer
                valid message tags.  This code has been checked for 
memory issues using valgrind for this
                size of problem.  So, unfortunately, I can't give a 
definitive reason fro this failure.


                                                                         
                                       Joe Kotulski
