Discussion of supported external interactions

Requests, issues, and questions¶

• provide gdb as a product

To-do (no particular order):

1. look into further reducing the time that it takes to create Fragment objects (and other bottlenecks) in V172xDriver_generator
2. write up instructions for using Totalview on the teststand nodes
3. include database storage hooks for MF messages
4. look into handling multiple DS50FragmentGenerators in one BoardReaderApp (the underlying issue is that both a 1495 trigger card and a TPC TDC card will be read out over the same fiber [since they will live in the same VME crate])
5. parallel NFS4 over Infiniband?
6. provide online DQM text to Alessandro
7. modify the EventBuilderApp so that the EventStore (and associated artapp) is created only once and the application complains if any new initialization strings request a reconfiguration of the EventStore or artapp

Software development milestones (obsolete)¶

Initial development milestones¶

1. start a demo system with an initial version of PMT
2. drive a dummy demo system through expected state transitions using a crude system control script
3. generate fake data in multiple boardreaders and build full events in multiple eventbuilders
   • part of this will be defining the configuration data for making the MPI connections
4. add eventbuilder disk writing to the fake data demo system
5. upgrade the fake data system to read out real hardware
