artdaq Release Notes 2.00.00 (10-Jan-2017)


This is a major version release of artdaq. New to this version is the TransferPlugin-based data transfer interface.
There are BREAKING CHANGES in this release:
  1. The expected FHiCL format has changed. Examples and generators for the new format are implemented in artdaq-demo v2_09_00. You must now specify each endpoint for data transfer, and which TransferPlugin will be used for that link.
  2. The RawInput source has been changed to no longer require the fragment_type_map FHiCL parameter. Instead, each project which defines its own fragment types must create their own input source which declares these types to the RawInput source. Examples are in artdaq-demo v2_09_00 (artdaq-demo/ArtModules/ and artdaq-core-demo v1_06_00 (artdaq-core-demo/Overlays/FragmentType.hh).

Through artdaq_core v1_06_00, this version of artdaq can be built against art v2_05_00 (s43), v2_04_01 (s44), or v2_03_00 (s41). It can be built with gcc v4_9_3a (e10).

Also, artdaq can be built with the Infiniband or Ethernet MPI libraries, and these are controlled by qualifiers ib and eth.

The default set of qualifiers for this version of artdaq is e10:s41:eth.
