TL;DR
DySM is a closed-loop response time control algorithm for spatially shared GPUs in soft real-time systems designed using feedback control theory for guaranteed system stability and control accuracy and outperforms state-of-the-art solutions by providing runtime real-time guarantees.
This work introduces CTA-pipelining, an execution paradigm designed to exploit shared-memory multi-GPU systems and demonstrates its capability using CUTLASS, cuBLAS, and NCCL libraries on 8-GPU H200 and B200 systems.

Current GPU Collective Communication Libraries (CCLs) employ predefined schedules optimized for stable environments. Their supported schedules and selection logic are fixed at communicator initialization, which fails to account for evolving runtime conditions, such as workload characteristics and hardware health status...

With the rapid growth of artificial intelligence (AI) and high-performance computing (HPC), GPUs and other accelerators have become a shared computing substrate for a wide range of workloads. However, many shared accelerator clusters still rely on coarse device-level allocation, which often leads to low effective utili...
