Syntax

--mpi-rank
=
<integer>
Arguments
<integer>
is the rank of the process with data to import.
Default
If an MPI rank is not specified, and there is more than one result directory in the project because the result partition is shared, a rank is chosen at random. Recommendation: Specify a rank.
Actions Modified
Usage
When you collect analysis data on a cluster, the data is stored in unique subdirectories under the project directory, named
rank.#
. Use this option to specify the process with data to import for viewing. You can import data from only one process at a time.
Example
Import MPI analysis data from the
rank.3
cluster. Read source files from the specified search directory. Write the result to the
advi_results
project directory.
$ advisor --import-dir=./advi --mpi-rank=3 --project-dir=./advi_results -- ./myApplication
