Modern intelligent cockpits consolidate In-Vehicle Infotainment (IVI), navigation, and control-related services on shared heterogeneous hardware. This consolidation creates a resource-management problem because cockpit workloads have different controllability, safety, and performance requirements. Existing open-source...

Dedicated VMs provide near bare-metal performance through CPU pinning, interrupt passthrough, and idle passthrough. In conventional deployments, however, these optimizations lock physical cores to individual VMs and prevent CPU sharing. In one of the world's largest cloud platforms, 74% of Dedicated VMs average below 1...

Xtream designs a mechanism for collaborative cold and hot data migration to ensure timely responses to VM I/O requests and identifies a macro-level locality pattern, characterized as multi-stripe disk access pattern, and develops a stripe-oriented prefetching algorithm in Xtream to improve I/O hit rate.

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...
