Summary
Level-1 Data Scouting (L1DS) is a novel data acquisition subsystem at the Compact Muon Solenoid (CMS) Level-1 Trigger (L1T) that exposes the L1T event selection data primitives for online processing at the 40 MHz bunchcrossing rate of the Large Hadron Collider (LHC), enabling unbiased and unconventional analyses. An L1DS demonstrator has been operating since Run 3, relying on a ramdisk for ephemeral storage of incoming and intermediate data, accessible by the system’s units through a Network File System (NFS). With the High-Luminosity LHC (HL-LHC) and the CMS Phase 2 upgrade projected to enhance trigger resolutions, a high-performance shared memory system is key to retain real-time processing capabilities in Run 4. For this, we leverage the emerging Compute Express Link (CXL) open standard
