`amplxe-cl` stores its trace data in directories (one per node). The example
script includes `-finalization-mode=none` as the finalize step is I/O intensive
and can take a long time. It is best done on an external login node. The
following `amplxe-cl` command creates a summary report which is then redirected
to another file. The `parse-vtune.sh` script is provided to extract the uncore
counter data for all nodes and then print a summary of the total data traffic
to the DDR memory. Note that each uncore count is a 64 byte cache line, which
is reflected in the total bytes reports. Also note that you will need to run a
summary report for each directory (one per node) created during data
collection. In this example, only a single directory was created. Even though
there is only a single summary file for this example, in the 2nd step of
executing `parse-vtune.sh` a wildcard is used to illustrate that all summary
files need to be specified on the command line for a multi-node result.
