RECIPE: REliable power and time-ConstraInts-aware Predictive management of heterogeneous Exascale

Status: Active Start:

Primary tabs


The current HPC facilities will need to grow by an order of magnitude in the next few years to reach the Exascale range. The dedicated middleware needed to manage the enormous complexity of future HPC centers, where deep heterogeneity isneeded to handle the wide variety of applications within reasonable power budgets, will be one of the most critical aspects in the evolution of HPC infrastructure towards Exascale. This middleware will need to address the critical issue of reliability inface of the increasing number of resources, and therefore decreasing mean time between failures. To close this gap, RECIPE provides:

  • a hierarchical runtime resource management infrastructure optimizing energy efficiencyand ensuring reliability for both time-critical and throughput-oriented computation;
  • a predictive reliability methodology tosupport the enforcing of QoS guarantees in face of both transient and long-term hardware failures, including thermal, timingand reliability models;
  • and a set of integration layers allowing the resource manager to interact with both the application andthe underlying deeply heterogeneous architecture, addressing them in a disaggregate way.

Quantitative goals for RECIPE include: 25% increase in energy efficiency (performance/watt) with an 15% MTTF improvement due to proactive thermal management; energy-delay product improved up to 25%; 20% reduction of faulty executions. The project will assess its results against the following set of real world use cases, addressing key application domains ranging from well established HPC applications such as geophysical exploration and meteorology, to emerging applicationdomains such as biomedical machine learning and data analytics. To this end, RECIPE relies on a consortium composed of four leading academic partners (POLIMI,UPV,EPFL,CeRICT); two supercomputing centers, BSC and PSNC; a research hospital, CHUV, and an SME, IBTS, which provide effectiveexploitation avenues through industry-based use cases.
