Under the terms of our in-kind proposal, the UK will be taking on 25% of the annual Data Release Processing workload; 50% will be performed at the French Data Facility, located at CC-IN2P3 in Lyon, and the remaining 25% will be undertaken by a US Data Facility, led from SLAC but including staff from several DOE labs and other sites. The three data facilities will operate as an integrated, distributed team, running the same software, but on potentially different kinds of computing hardware, as available in the three countries. The US Data Facility is responsible for the middleware needed to support this distributed mode of operation, and, of course, the DRP pipeline software itself is the responsibility of the Rubin Observatory.
The UK in-kind proposal includes 5 FTE of staff effort to undertake our quarter-share of the DRP workload. The details of the work required to meet that obligation is still under discussion with the USDF leadership, and the range of existing skills required will be dependent on the choice of middleware technologies selected by the USDF, some of which remain to be confirmed.
Once those discussions have concluded, we shall post here a set of DRP WP or role descriptions (whichever is more appropriate), along with a timeline for institutions to bid to undertake them, in a manner similar to that followed for the DAC WP in Phase B. Further information about this process will be circulated to lusc-announce email list.
