Performance and power modeling

This circular arrows diagram example shows the Performance and Architecture Laboratory (PAL) circle. It was designed on the base of the diagram on the article "Advanced Computing, Mathematics and Data Division Research Highlights" webpage from the website of the Pacific Northwest National Laboratory of the U.S. Department of Energy. "The Performance and Architecture Laboratory, or PAL, at Pacific Northwest National Laboratory (PNNL) takes on power and energy problems affecting high-performance computing (HPC), especially issues that may impact achieving practical performance at the exascale. Using methods that span processor architecture and system integration to software and programming models to performance and power modeling, PAL scientists, who are part of PNNL's HPC Group, have developed power-aware algorithms that use an accurate per-core proxy power sensor model to estimate the active power of each core. Their methods also have afforded the first workload-specific quantitative power modeling capability that accurately captures workload phases, their impact on power consumption, and the effects of system architecture and processor clock speeds." [pnnl.gov/science/highlights/highlight.asp?id=1572] The arrow circle diagram example "Performance and power modeling" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Circular Arrows Diagrams solution from the area "What is a Diagram" of ConceptDraw Solution Park.
