This report examines performance of four models with two compilers on the Intel Pentium 4 Xeon processor using the PAPI performance event library to collect performance counter values. The intent is to identify performance metrics that indicate where performance inhibiting factors occur when the codes execute. Results for operations, instructions, cycles, cache, table lookaside buffer misses, b...

The control of particulate matter emissions from cotton gins is a priority in many states. The air pollution regulatory process requires that concentrations measured off-property be less than the National Ambient Air Quality Standards. Two methods are commonly used to determine the concentrations on or beyond the property line: ambient sampling and dispersion modeling. In order to limit the emi...
