Formats an event log (.etl) file as a CLOG event file for use with the Jumpshot viewer from Argonne National Laboratory.

For examples of how to use this command, see Examples.


etl2clog <.etl_file_name>

The etl2clog command is a Message Passing Interface (MPI) program. Run it with the mpiexec command to distribute formatting work across each node that is used in a job, and then collect the results in a single output file on the rank 0 node. The output file has a file name extension of .clog2.

The etl2clog command applies clock corrections as it formats the binary trace data, if you used the mpicsync command to create clock-corrected .etl files.


To format the event log mpi_trace_37.1.0.etl as a CLOG event file, use the following command:

mpiexec /cores 1 etl2clog mpi_trace_37.1.0.etl
