It contains various modules and data structres: an EDProducer to convert PFJets to a simplified SoA format - a heterogeneous global::EDProducer running on CPU - SoA data structures - automatic data transfers from host to device an EDProducer to apply residual jet corrections on GPU - an asynchronous global::EDProducer running on GPU - a simple 1D kernel an ESProducer for the jet corrections - a new EventSetup record - new “portable” data structures and EventSetup conditions - a heterogeneous ESProducer an EDProducer to find all jet pairs and triplets passing some selection criteria - a stream::SynchronizingEDProducer - new persistent and local SoA data structures - automatic copy of a configuration object to the GPUs - more complex 2D and 3D kernels an EDAnalyzer to print the N-tuplets - a traditional edm::EDAnalyzer running on CPU - automatic data transfers from device to host It also contains a configuration file to run the full job on GPUs or on CPU.
