Hi everyone,
I am currently debugging some code and have been printing out (using
either CCTK_INFO and/or printf) debugging information at particular
grid points (LOCAL mode).
From what I can tell, Cactus only allows output from one process, say
rank 0, to stop flooding of the output by printing everything once
per process. However if I am wanting data from a particular grid
point, and this grid point is not in the printing process, nothing
will output.
I have been getting around this by turning off MPI (fine for one
iteration or so) but now I am doing longer runs I need to be able to
print out this information with MPI.
Thus my question:
How can you force Cactus to print out a statement from any process?
Add -roe to the Cactus command line and you will get separate output
and error files from each process.
