Open Source Distributed Computing Software

SocketTest - powerful and small software tool for socket testing. It can create both TCP and UDP client or server. It can be used to test any server or client that uses TCP or UDP protocol to communicate.

Project continued at github, see https://github.com/wolfc01/procexp/blob/master/README.md Graphical process explorer for Linux. Shows process information: process tree, TCP IP connections and graphical performance figures for processes. Aims to mimic Windows procexp from sysinternals, and aims to be more usable than top and ps, especially for advanced users. Audience for this tool: * Advanced system administrators trying to analyze on process level what is going on in a production server; * Software developers analyzing the troughput of their process: e.g. TCP throughput, memory usage, memory leaks; The most advanced feature is the monitoring of TCP/IP traffic figures, for each SINGLE process (actual connections and throughput). As far as known no other tool has this capability. In the process tree, use the right mouse button to monitor process details.

RPyC, or Remote Python Call, is a transparent and symmetrical python library for remote procedure calls, clustering and distributed-computing.

CoDeK - Java Concurrent Development frameworK is a very simple, open-source, academic java library aimed to help the development of Java multi-threading concurrent applications.

The GridUnit project is a first effort to use the huge heterogeneity and distributed nature of Computational Grids to imporve the software testing process. It is an extension of the widelly adopted JUnit testing framework.

A generic java based distributed performance testing platform specifically for testing clustered or distributed applications and or frameworks. The framework itself is clustered and coordinated with www.terracotta.org

A distributed logging & monitoring WS architecture using WS-Notification (WSN) as well as a Log4J appender that implements an appropriate adapter. Software components that already use Log4J can be integrated non-intrusively.

A test suite to MPI-2 and threads.

Tools, information, and practices for creating and operating dependable, complex, distributed, software-intensive systems. * Sense - Measure - Analyze - Respond - Optimize * Keywords: Performance Co-Pilot - PCP - PCPMon - Rjobd

OpenLC is a set tools designed to facilitate benchmarking and stress testing of a wide variety of information servers (WEB, Email, FTP, LDAP, ...). A XML-RPC API is offered for developers interested in creating clients that query the services provid

This project provides a distributed testing environment that extends JUnit. Giving the developer/tester an ability to run remote JUnits and create complex test suites that are composed of several remote JUnit tests running in parallel or serially.

The alio library can be dynamically pre-linked to existing executables and replaces file IO (i.e. calls to glibc's IO functions). This allows to gather statistics about IO, create IO trace files, or even implement a different IO behaviour (e.g. use separate IO servers to handle IO).

mxtraf is a network traffic generator. With mxtraf, a small number of hosts can be used to saturate a network with a tunable mix of TCP and UDP traffic. The primary purpose of mxtraf is to allow stress testing of experimental network protocols. m
