GPU Computing for Atmospheric Modeling
Found in: Computing in Science and Engineering
By Rory Kelly
Issue Date:July 2010
pp. 26-33
Much success has been achieved using GPUs to accelerate existing applications that are highly data parallel, or that are dominated by small, intense computational kernels. What are the prospects for porting existing large scientific models that do not fit ...
System-level monitoring of floating-point performance to improve effective system utilization
Found in: State of the Practice Reports (SC '11)
By David L. Hart, Davide Del Vento, Richard Valent, Rory Kelly, Si Liu, Siddhartha S. Ghosh, Thomas Engel
Issue Date:November 2011
pp. 1-6
NCAR's Bluefire supercomputer is instrumented with a set of low-overhead processes that continually monitor the floating-point counters of its 3,840 batch-compute cores. We extract performance numbers for each batch job by correlating the data from corresp...
