In this paper, we examine the performance of a suite of applications on three different architectures: Edison, a Cray XC30 with Intel Ivy Bridge processors; Hopper and Cielo, both Cray XE6's with AMD Magny–Cours processors; and Mira, an IBM BlueGene/Q with PowerPC A2 processors. The applications chosen are a subset of the applications used in a joint(More)
We present preliminary results of the Roofline Toolkit for multicore, manycore, and accelerated architectures. This paper focuses on the processor architecture characterization engine, a collection of portable instrumented micro benchmarks implemented with Message Passing Interface (MPI), and OpenMP used to express thread-level paral-lelism.
