This paper discusses the integration of these GPGPU programs with OpenMP to create lattice-Boltzmann applications for multi-GPU clusters. Cloud providers offer local and exclusive access to GPUs by using PCI passthrough. If you tend to run a number of applications at one time or use photo and video editing software, then a startup drive can go a long way toward making these programs run smoother and load faster. As miniaturization approaches its limits, bringing an end to Mooreâs law, performance gains will need to come from software, algorithms, and hardware. The performance of each component can be determined globally and for each computational phase. The main contribution of this methodology is a semi-automatic prediction of the performance for sequential applications on a set of parallel architectures. This framework is more informative than simple benchmarking, or microbenchmarking. 0000065695 00000 n

The word performance in computer performance means âHow well is the computer doing the work it is supposed to do?â. Performance seems to have two meanings: 1) The speed at which a computer operates, either theoretically (for example, using a formula for calculating Mtops - millions of theoretical instructions per second) or by counting operations or instructions performed (for example, ( MIPS) - millions of instructions per second) during a benchmark test.

These strategies help discover problems related to memory access locality and loop unrolling that lead to a sequential performance improvement of a factor of 2. By examining single- and multi-GPU lattice-Boltzmann simulations with ANOVA, we show that all the lattice-Boltzmann simulations primarily depend on effects corresponding to simulation geometry and decomposition, and not on the architectural aspects of GPU.
