Hello,<br><br>I have earlier used mpe2 to profile an application (WRF) in other configurations but I am getting the following error when I use MPE2 with mvapich using intel compilers. However, simple mpi program does not give me any error and successfully clog2 file is produced. Can you tell me why this is happening and how should I debug this?<br>
