For the above command, assuming there are multiple calib cycles in run 71 of xpptut13 that each have at least 100 events, and that the batch job was 39283, you will produce the following files:

translate_39283.out
mydir/split.h5
mydir/split_cc0000.h5
mydir/split_cc0001.h5
...

When moving the hdf5 files, make sure they all reside in the same directory. The links from the master to the calib cycle files assume they are in the same directory.

The job output file (translate_39283.out) will record timing information for the master and workers. Identifying the optimal number of nodes for h5-mpi-translate requires further analysis, however you can identify idle workers or a poor distribution of the work by looking at the report in the batch job output file.

Non-MPI Split Scan

To run the Translator in split scan mode without MPI, three options must be set. These options do the following:

...

In this mode, each Translator job reads through the entire set of xtc files. As more and more Translator jobs are run simultaneously, the overall speed of translation diminishes while the load on the network steadily increases. It is recommended that users run no more than 5 Translator jobs. Testing has show shown 5 jobs provide up to a three times speed up in translation for the non-mpi mode. (greater speedups have been seen with the MPI version).
