Theoretical Peak FLOPS per instruction set on modern Intel CPUs
نویسنده
چکیده
It used to be that evaluating the theoretical peak performance of a CPU in FLOPS (floating point operations per seconds) was merely a matter of multiplying the frequency by the number of floating-point instructions per cycles. Today however, CPUs have features such as vectorization, fused multiply-add, hyper-threading or “turbo” mode. In this paper, we look into this theoretical peak for recent full-featured Intel CPUs., taking into account not only the simple absolute peak, but also the relevant instruction sets and encoding and the frequency scaling behavior of current Intel CPUs.

Modeling the Performance of Geometric Multigrid on Many-core Computer Architectures
The basic building blocks of the classic geometric multigrid algorithm are all essentially stencil computations and have a low ratio of executed floating point operations per byte fetched from memory. On modern computer architectures, such computational kernels are typically bounded by memory traffic and achieve only a small percentage of the theoretical peak floating point performance of the u...
متن کاملParallelizable and Authenticated Online Ciphers
Online ciphers encrypt an arbitrary number of plaintext blocks and output ciphertext blocks which only depend on the preceding plaintext blocks. All online ciphers proposed so far are essentially serial, which significantly limits their performance on parallel architectures such as modern general-purpose CPUs or dedicated hardware. We propose the first parallelizable online cipher, COPE. It per...

متن کاملLong-time simulations with complex code using multiple nodes of Intel Xeon Phi Knights Landing
Modern partial differential equation (PDE) models across scientific disciplines require sophisticated numerical methods resulting in complex codes as well as large numbers of simulations for analysis like parameter studies and uncertainty quantification. To evaluate the behavior of the model for sufficeintly long times, for instance, to compare to laboratory time scales, often requires long-tim...
متن کاملSSE Implementation of Multivariate PKCs on Modern x86 CPUs
Multivariate Public Key Cryptosystems (MPKCs) are often touted as future-proofing against Quantum Computers. It also has been known for efficiency compared to “traditional” alternatives. However, this advantage seems to erode with the increase of arithmetic resources in modern CPUs and improved algorithms, especially with respect to Elliptic Curve Cryptography (ECC). In this paper, we show that...
