I guess that the TAU-instrumented binary is in folder
"Release__tau-t1-mpi-pdt-profile-trace__tau-t1-mpi-pdt-profile-trace" (the latest in my workspace's folder).
So, when I run the instrumented executable from command line, I get the following output...
mpiuser@n00:~/workspace1/demo1/Release__tau-t1-mpi-pdt-profile-trace__tau-t1-mpi-pdt-profile-trace$ mpirun -np 4 ./demo1
Num processes: 4
Process 0 received "Greetings from process 1!"
Process 0 received "Greetings from process 2!"
Process 0 received "Greetings from process 3!"
Process 1 received "Hi, how are you?"
Process 2 received "Hi, how are you?"
Process 3 received "Hi, how are you?"
PI is approximately 3.1415926535897931

But when I compile and run the same source file from command line, it runs fine and produces some output .edf and .trc files.
