Improvement of branch predictors has been one of the focal points of computer architecture research during the last decade, ranging from two-level predictors to complex hybrid mechanisms. Most research efforts try to use real, already implemented, branch predictor sizes and organizations for comparison and evaluation. Yet, little is known about exact predictor implementation in Intel processors...

The Skylake Xeon (called Xeon Scalable processor) introduced a number of innovations, notably AVX-512 vectorization instructions capable of 8-wide double precision vectors (previous AVX2 had 4-wide DP vectors). This change in itself has a potential of doubling performance of floating point codes. Other changes include CPU core optimizations, rearchitecture of the caches, and new, mesh-based top...

The crisis of neoliberal globalization has led many scholars back to Karl Polanyi in their search for alternatives to the present malaise. The dominant reading appropriates the concepts of embeddedness and the double movement in support of a system of regulated, welfare-state capitalism. This article contends, however, that the concepts of embeddedness and the double movement point not towards ...

This application note provides detailed design procedures for the development of the Core supply for Intel Pentium II and beyond motherboards using Fairchild Semiconductor’s third generation controller RC5052/RC5057 both of which were designed to meet the Intel VRM8.4 specification.

Intels processors based on the original 45nm Intel Coret microarchitecture, originally referred to by the codename Penryn, improved the energy efficiency and performance per watt of the Intel Core microarchitecture. This paper discusses the new technologies introduced in the Penryn family of processors that enabled lower idle power and higher performance levels. The Penryn family of processors ...

In this paper we demonstrate the methodology for parallelizing the computation of large one-dimensional discrete fast Fourier transforms (DFFTs) on multi-core Intel Xeon processors. DFFTs based on the recursive Cooley-Tukey method have to control cache utilization, memory bandwidth and vector hardware usage, and at the same time scale across multiple threads or compute nodes. Our method builds ...

Energy efficiency in large data centers is already a concern for many businesses because of the high density of energy consumption. Rising energy costs and global environmental concerns have prompted Information Technology (IT) professionals to also take a closer look at client personal computer (PC) energy consumption. Intel researchers interviewed IT professionals about the monitoring and con...
