Abstract

A growing number of "second generation" high-performance computing applications with heterogeneous, dynamic and data-intensive properties have an extended set of requirements, which cover application deployment, resource allocation, -control, and I/O scheduling. These requirements are not met by the current production HPC platform models and policies. This results in a loss of opportunity, productivity and innovation for new computational methods and tools. It also decreases effective system utilization for platform providers due to unsupervised workarounds and "rogue'" resource management strategies implemented in application space. In this paper we critically discuss the dominant HPC platform model and describe the challenges it creates for second generation applications because of its asymmetric resource view, interfaces and software deployment policies. We present an extended, more symmetric and application-centric platform model that adds decentralized deployment, introspection, bidirectional control and information flow and more comprehensive resource scheduling. We describe cHPC: an early prototype of a non-disruptive implementation based on Linux Containers (LXC). It can operate alongside existing batch queuing systems and exposes a symmetric platform API without interfering with existing applications and usage modes. We see our approach as a viable, incremental next step in HPC platform evolution that benefits applications and platform providers alike. To demonstrate this further, we layout out a roadmap for future research and experimental evaluation.
