  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.
