How do Volkov and Demmel experimentally determine the latencies, line sizes, and page sizes of a GPU?
In "LU, QR and Cholesky Factorizations using Vector Capabilities of GPUs", by Vasily Volkov and James Demmel, there is an interesting way to interpret the latencies, line sizes, and page sizes of a ...
CPU benchmarks available online mostly focus on desktop apps/games and rarely on serial/parallel numerical kernels, specially sparse ones (e.g., MatMult). Some benchmarks like NAS/SciMark exists but ...
I am using a program that utilizes the PARDISO solver as part of the Intel math kernel library. I am currently in the process of deciding on a new computer to run the simulations on. I have a ...
This question is an extension of two discussions that came up recently in the replies to "C++ vs Fortran for HPC". And it is a bit more of a challenge than a question... One of the most often-heard ...
Informally in our lab, we have developed 2 metrics to compare CFD solvers over the range of machines we have access to. One is called COMP, which stands for COde Machine Performance. This single ...
