The quantitative analysis of software projects can provide insights that let us better understand open source and other software development projects. An important variable used in the analysis of software projects is the amount of work being contributed, the commit size. Unfortunately, post-facto, the commit size can only be estimated, not measured. This paper presents several algorithms for e...

Performance is often a key factor in determining the success of a parallel software system. various techniques, and surveys work done in each category. Also addressed and discussed are other issues related to performance evaluation. These issues include how to select metrics and proper techniques that are well suited for the particular development stage, how to construct a good model, and how t...

In today’s competitive business and industrial environment, it is becoming more crucial than ever to assess precisely process losses due to noncompliance to customer specifications. To assess these losses, industry is extensively using Process Capability Indices for performance evaluation of their processes. Determination of the performance capability of a stable process using the standard proc...

This paper describes a software architectural design method for large-scale distributed information systems. The method, which is part of an integrated design and performance evaluation method, addresses the design of client/server software architectures, where the servers need to cooperate with each other to service client requests. The goal of this software architecture is to provide a concur...

Hardware-software (HW-SW) codesign is an attempt to integrate hardware and software design techniques. A critical feature of all codesign methods is evaluation of the performance of the system. The best approach is to estimate performance based on the high-level specifications of the system before starting the subsequent partitioning and synthesis phases: these phases waste a large amount of re...

This paper presents a new tool, named SDL Performance Evaluation Tool (SPEET) 2 , for the performance analysis of formally speciied systems under real{time conditions. SPEET facilitates the simulation and emulation of several formal speciications at the same time. The systems to be simulated, resp. to be emulated, can be triggered by traac load generators and can be interconnected with transmis...

The volume of data generated by modern astronomical telescopes is extremely large and rapidly growing. However, current high-performance data processing architectures/frameworks are not well suited for astronomers because of their limitations and programming difficulties. In this paper, we therefore present OpenCluster, an open-source distributed computing framework to support rapidly developin...

Application-level monitoring of continuously operating software systems provides insights into their dynamic behavior, helping to maintain their performance and availability during runtime. Such monitoring may cause a significant runtime overhead to the monitored system, depending on the number and location of used instrumentation probes. In order to improve a system’s instrumentation and to re...

Driven by the urging need to thoroughly identify and accentuate the merits of agent technology, we present in this paper MEANDER, an integrated framework for evaluating the performance of agent-based systems. The proposed framework is based on the Agent Performance Evaluation (APE) methodology, which provides guidelines and representation tools for performance metrics, measurement collection an...

Developers need to evaluate software’s performance to make software efficient. This paper suggests a performance evaluation system for embedded software. The suggested system consists of code analyzer, testing agents, data analyzer, and report viewer. The code analyzer inserts additional code dependent on target system into source code and compiles the source code. The testing agents execute pe...
