= Jumel (JUROPA memory logger) =

== General information ==
The JUROPA memory logger is intended for monitoring the memory usage of applications on NUMA architectures (especially JUROPA). It consists currently of two Python scripts:
  * jumel (JUROPA memory logger), the actual logger
  * juman (JUROPA memory analyzer), a postprocessing tool

== Usage ==
Suppose the application to monitor is started usually as follows:

{{{
mpiexec -np 32 -e APP_ROOT app.x -i app.inp
}}}

To start the application with jumel use


{{{
mpiexec -np 32 -e PBS_ID,APP_ROOT jumel -a "app.x -i app.inp"
}}}

The variable PBS_ID needs not to be specified, how ever it will be displayed in the jumel logfiles and eases the tracking of the runs afterwards (e.g. when looking for the job in the system logfiles).
