Jodd is a Java utility library and set of frameworks. Jodd tools enrich the JDK with many powerful and feature rich utilities. It helps with everyday tasks, and makes code more robust and reliable. Jodd frameworks is set of lightweight application frameworks, compact yet powerful. Designed following the CoC, DRY, and SCS principles, it makes development simple, but not simpler; you get 90% of the features with 10% of the usual effort.
libmemcached is a C client library for interfacing to a memcached server. It has been designed to be light on memory usage, thread safe and to provide full access to server side methods. It also implements several command line tools: memcat, memflush, memrm, memstat, and memslap (for load generation). The library has been designed to allow for different hashing methods on keys, partitioning by keys, and to use consistent hashing for distribution.
Open MPI is a project that originated as the merging of technologies and resources from several other projects (FT- MPI, LA-MPI, LAM/MPI, and PACX-MPI) in order to build the best MPI library available. A completely new MPI-2 compliant implementation, Open MPI offers advantages for system and software vendors, application developers, and computer science researchers. It is easy to use, and runs natively on a wide variety of operating systems, network interconnects, and batch/scheduling systems.
MUSCLE (Multi User Server Client Linking Environment) is an N-way messaging server and networking API. It includes client-side networking APIs for various languages, including C, C++, C#, Delphi, Java, and Python. MUSCLE lets programs communicate over a network via streams of serialized Message objects. The included server program ("muscled") lets its clients message each other and store information in its server-side hierarchical database. The database supports flexible queries via hierarchical wildcarding, and "live" updates via a subscription mechanism.
Python bsddb3 is a Python module that provides a nearly complete wrapping of the Oracle/Sleepycat C API for the database environment, database, cursor, sequence, and transaction objects, and each of these is exposed as a Python type in the bsddb3.db module. The database objects can use various access methods: btree, hash, recno, and queue. It has complete support for Berkeley DB distributed transactions, and complete support for the Berkeley DB Replication Manager and base replication API. The goal is to mirror most of the real Berkeley DB API.
