This update offers controlled horizontal scaling.</div><div class="">As you recall, for batch processing CLARA accepts input data-set in the form of a metadata file, containing the names of data files to be processed ( files.list). Before this update the files within the files.list was processed serially within the single DPE/node. In this case the only scaling factor was due to the CLARA vertical scaling, i.e. multi-threading through available cores of the node.</div><div class="">In this update we are presenting a new CLARA configuration parameter: farm.scaling</div><div class="">The default value is set to be 0 - no horizontal scaling, however in case user sets farm.scaling=n, that will tell CLARA to process groups of n files from the files.list data-set in parallel, on different farm nodes, thus speeding up input data-set processing n times. </div><div class=""><div class=""><br class=""></div><div class="">For more detailed documentation of this feature visit:</div><div class=""><a href="https://claraweb.jlab.org/clara//docs/clas/clara-scaling.html" class="">https://claraweb.jlab.org/clara//docs/clas/clara-scaling.html</a></div></div><div class=""><br class=""></div><div class="">Note: to activate this feature you need to update your local CLARA installations:</div><div class=""><a href="https://claraweb.jlab.org/clara//docs/clas/installation.html" class="">https://claraweb.jlab.org/clara//docs/clas/installation.html</a></div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">Best regards,</div><div class="">-vardan</div><div class=""><br class=""><div class="">
