          Discussion on Common Projects 30m

          Establish a link between the Scientific Computing and the Scientific Software groups:

          • Short-term goal (3-6 months): demonstrate benefits of RNTuple in a shared environment (many clients to XRootD or EOS)

          • Longer-term common projects

            • Storage API evolution (e.g., key-value store)
            • Information exchange between storage and application layer (e.g. caching hints, TTreeStats/RNTupleMetrics, block size hints)
          • Storage hardware evolution at scale
          • Impact of erasure coding
          • Common benchmarks and visualization of access data
