This week we spoke with Jörg Lotze, CTO and cofounder of financial services-driven software firm, Xcelerit, about benchmarking accelerators, coprocessors, and multicore architectures with specific emphasis on how GPUs stack up against Intel Xeon Phi coprocessors. Lotze discussed the challenges and opportunities of each in the context of real-world Monte Carlo examples.
Today at the International Supercomputing Conference in Leipzing, Germany, Jack Dongarra presented on a proposed benchmark that could carry a bit more weight than its older Linpack companion. The high performance conjugate gradient (HPCG) concept takes into account new architectures for new applications, while shedding the floating point….
How does the Phi coprocessor measure up to Xeon “Sandy Bridge” brand-mate?
The Standard Performance Evaluation Corporation (SPEC) has formed a working group to define cloud benchmark methodologies.
Newest Intel Xeon chip proves its worth for artithmetic-heavy codes.
A recent effort led by Cycle Computing based on the SHOC benchmark revealed equal performance between GPU-accelerated cloud and native hardware.
The STREAM benchmark plays to one of the big strength of Intel’s Nehalem architecture — its memory performance.
Intel’s Nehalem gets Linpunked.
