NovAtel's Novel Approach to CPU Usage Measurement
نویسنده
چکیده
This paper describes a set of CPU usage analysis tools, named CPU Probes, with the benefits of both hardware and software tools, and few of their disadvantages. CPU probes use a serial line unit or programmable interval timer as a clock to sample the CPU usage of a system, resulting in fast and accurate CPU usage estimates. CPU usage can be monitored for all processes simultaneously or as little as a single machine instruction. CPU probes are well suited for monitoring real-time system peformance. These tools have been implemented on PDP-11/RSX and UNIX System V/386 systems.

A Method for Measuring Energy Consumption in IaaS Cloud
The ability to measure the energy consumed by cloud infrastructure is a crucial step towards the development of energy efficiency policies in the cloud infrastructure. There are hardware-based and software-based methods of measuring energy usage in cloud infrastructure. However, most hardware-based energy measurement methods measure the energy consumed system-wide - including the energy lost in...
متن کاملReducing operational costs through MIPS management
We focus on an approach to reducing costs of running applications. MIPS, which is a traditional acronym for millions of instructions per second, have evolved to become a measurement of processing power and the CPU resource consumption. The need for controlling MIPS attributed costs is indispensable given the high percentage they involve in the operational IT costs. In this paper we investigate ...
متن کاملA Novel Approach for Direct Preparation of Hydroxyapatite Nanoparticles from natural source using Microwave
Hydroxyapatite (HA) is one of the most common biocompatible ceramic with wide usages in various aspects of medicine due to the resemblance to the mineral bone tissue. The particle size of HA has a key roll in determination of the reaction rate at the interface of natural bones/artificial. Accordingly, this paper tries to propose a novel approach for the preparation of HA nanoparticles from natu...

This paper extends the previous work of authors and presents a non-layered Finite Volume formulation for the elasto-plastic analysis of Mindlin-Reissner plates. The incremental algorithm of the elasto-plastic solution procedure is shown in detail. The performance of the formulation is examined by analyzing of plates with different boundary conditions and loading types. The results are illustrat...
متن کاملStatistical Regression to Predict Total Cumulative CPU Usage of MapReduce Jobs
recently, businesses have started using MapReduce as a popular computation framework for processing large amount of data, such as spam detection, and different data mining tasks, in both public and private clouds. Two of the challenging questions in such environments are (1) choosing suitable values for MapReduce configuration parameters –e.g., number of mappers, number of reducers, and DFS blo...
