Field testing refers to testing techniques that operate in the field to reveal those faults that
escape in-house testing. Field testing techniques are becoming increasingly popular with …

We present here a report produced by a workshop on 'Addressing failures in exascale
computing'held in Park City, Utah, 4–11 August 2012. The charter of this workshop was to …

We present a scalable temporal order analysis technique that supports debugging of large
scale applications by classifying MPI tasks based on their logical program execution order …

Developing correct HPC applications continues to be a challenge as the number of cores
increases in today's largest systems. Most existing debugging techniques perform poorly at …

Cutting-edge science and engineering applications require petascale computing. It is,
however, a significant challenge to use petascale computing platforms effectively …

Detecting and isolating bugs that arise in parallel programs is a tedious and a challenging
task. An especially subtle class of bugs are those that are scale-dependent: while small …

Parallel tools require common pieces of infrastructure: the ability to control, monitor, and
instrument programs, and the ability to massively scale these operations as the application …

A key challenge in developing large scale applications is finding bugs that are latent at the
small scales of testing, but manifest themselves when the application is deployed at a large …

Extreme-scale computing poses a number of challenges to application performance.
Developers need to study application behavior by collecting detailed information with the …
