distributed.net is a loosely knit group of computer users from all of the world that is taking up challenges requiring lots of computing power (most notably the RC5, DES, and OGR cracking contests). It is simple to participate in the challenges by downloading and running their client software (which uses idle CPU time to complete its tasks).
PVM (Parallel Virtual Machine) is a portable message-passing programming system, designed to link separate host machines to form a ``virtual machine'' which is a single, manageable computing resource. The virtual machine can be composed of hosts of varying types, in physically remote locations. PVM applications can be composed of any number of separate processes, or components, written in a mixture of C, C++ and Fortran. The system is portable to a wide variety of architectures, including workstations, multiprocessors, supercomputers and PCs.
Platform Independent Petri Net Editor (PIPE) creates and analyses Petri Nets quickly, efficiently, and effectively. A key design feature is the modular approach adopted for analysis, enabling new modules to be written easily and powerfully, using built-in data layer methods for standard calculations. Six analysis modules are provided, including Invariant Analysis, State-Space Analysis (deadlock, etc.), and Simulation Analysis and Classification. PIPE adheres to the XML Petri net standard (PNML). The file format for saving and loading Petri Nets is extensible through the use of XSLT, the default being PNML.
JCGrid is a set of easy-to-use tools for real-world grid-computing. It doesn't require any file system sharing capability (such as NFS). It allows you to easily split a CPU-intensive task among several computers by using the JCGrid framework. Any file required for completing the task will be transferred by the framework. A cache is used in order to minimize file transfers. You can easily add or remove computers from the grid at runtime without losing any work. Support for POVRay is included as an example of use.
MQ4CPP, or "Message Queuing for C++", is an implementation of an enterprise messaging system, also referred to as message-oriented middleware (MOM). It enables C++ application threads to communicate with other threads locally or remotely through the exchange of messages. A message is a request, report, and/or event that contains information needed to coordinate communication between different applications. MQ4CPP implements direct/indirect messaging, unsolicited messaging, request/reply, conversation, publish/subscribe, store & forward, and broadcast. It supports multithreading, application clustering (failover and session replication), and encryption. MQ4CPP also includes a distributed lock manager, a file transfer manager, and a distributed memory channel.
Moab Grid Suite is a professional grid workload management solution that integrates scheduling, management, monitoring, and reporting of workloads across independent clusters. Moab makes moving to a grid easy by adding grid-optimized job submission and management in a matter of minutes. Moab optimizes data staging and seamlessly integrates with existing security mechanisms or with grid security tool kits such as Globus. It gives sites extensive control over ownership-based access, priority, and service levels. It provides fine-tuned control over the workload and resources to make the grid usable.
TORQUE is a resource manager that provides control over batch jobs and distributed compute nodes. It is a community effort based on the original *PBS project and, with more than 1,200 patches, it has incorporated significant advances in the areas of scalability, fault tolerance, and feature extensions.
Equalizer is middleware for creating and deploying parallel OpenGL-based applications. It enables applications to benefit from multiple graphics cards, processors, and computers to scale rendering performance, visual quality, and display size. An Equalizer-based application runs unmodified on any visualization system, from a simple workstation to large scale graphics clusters, multi-GPU workstations, and Virtual Reality installations.
