The ghost in the machine

Aroon Nataraj, Alan Morris, Allen D. Malony, Matthew Sottile, Pete Beckman
2007 Proceedings of the 2007 ACM/IEEE conference on Supercomputing - SC '07  
To understand the influences of system-level factors on application performance, the measurement of OS kernel activities is key.  ...  The performance of a parallel application on a scalable HPC system is determined by user-level execution of the application code and system-level (OS kernel) operations.  ...  Department of Energy, Office of Science, under contracts DE-FG02-05ER25663 (Extreme Performance Scalable Operating Systems) and DE-FG02-05ER25680 (Application-Specific Performance Technology for Productive  ...

Modeling and predicting application performance on parallel computers using HPC challenge benchmarks

Wayne Pfeiffer, Nicholas J. Wright
2008 Proceedings, International Parallel and Distributed Processing Symposium (IPDPS)  
A method is presented for modeling application performance on parallel computers in terms of the performance of microkernels from the HPC Challenge benchmarks.  ...  These models not only describe performance well on the ten computers used to build the models, but also do a good job of predicting performance on three additional computers with newer design features.  ...  Greg Bauer and Nahil Sobh of NCSA provided many results on systems with Intel processors as part of the Cyberinfrastructure Partnership supported by the National Science Foundation.  ...

Software challenges in extreme scale systems

Vivek Sarkar, William Harrod, Allan E Snavely
2009 Journal of Physics, Conference Series  
probably represents the first true parallel processor to fly in space, and one of the earliest examples of multi-threaded architectures.  ...  His Ph.D. thesis on the parallel solution of recurrence equations was one of the early works on what is now called parallel prefix, and applications of those results are still acknowledged as defining  ...  One can raise an argument as to whether the numerator (the single processor case) should be assuming the same code as run on multiple processors, or for an optimal code written for exactly one processor  ...
