Since 1.9.5 the EventBuilder has been modified. Please consult the documentation
where the new mevb scheme is explained.
Test of the mevb with up to 16 frontends (15 different CPUs) has been tested
successfully. Data rate at the EventBuilder were measured about 50MB/s without the
logger and ~30MB/s with the logger. |
