As software and systems scale, and get deployed to large-scale, uncertain infrastructure, it is increasingly important to develop resilient and adaptive cyberinfrastructure:
Bugs that arise in applications run on large inputs at large scales are hard to detect and diagnose.
Scalability bottlenecks prevent applications from smoothly scaling up to larger inputs and systems
As hardware gets more complex, heterogeneous, and unreliable, applications need to be able to migrate between systems and adapt from one type or hardware to another
Key insights to build resilient and adaptive infrastructure:
Build models of application behavior that scale up to large inputs and large systems to detect and diagnose bugs
Develop compiler transformations, optimizations and runtime systems to allow applications to map effectively to multiple hardware platforms
Examples:
Novel scaling models of application behavior allow bugs in large scale systems to be developed based on models efficiently built at small scales
New compiler transformations have shown how same parallel application can be mapped to multicores, Xeon Phis, and SIMD units.
Current Operational Capability:
Unique capabilities demonstrated
First bug-detection tools that can detect scaling bugs without modeling large-scale behavior (HPDC 2011, 2013)
First programming model for elastic cloud programs that automatically scale up and down at runtime based on available resources (HPDC 2011, SoCC 2013)
First local alignment tool that exploits query fragmentation to break scaling bottleneck in BLAST (Supercomputing 2014)
