Abstract

The future of computing systems is inevitably embracing a disaggregated and composable pattern: from clusters of computers to pools of resources that can be dynamically combined together and tailored around applications requirements. Transitioning to this new paradigm requires ground-breaking research, ranging from new hardware architectures up to new models and abstractions at all levels of the software stack. Recent hardware advancements in CPU and interconnection technologies, enabled the possibility of disaggregating peripherals and system memory. The memory system heterogeneity is further increasing, composability and disaggregation are beneficial to increase memory capacity and improve memory utilization in a cost-effective way, and reduce total cost of ownership. Heterogeneous and Composable Disaggregated Systems (HCDS) provide a system design approach for reducing the imbalance between workloads resource requirements and the static availability of resources in a computing system. The HCDS workshop aims at exploring the novel research ideas around composable disaggregated systems and their integration with operating systems and software runtimes to maximize the benefit perceived from user workloads.
