Son of Grid Engine is a highly-scalable and versatile distributed resource manager for scheduling batch or interactive jobs on clusters or desktop farms. It is a community project to continue Sun's Grid Engine. It is competitive against proprietary systems and provides better scheduling features and scalability than other free DRMs like Torque, SLURM, Condor, and Lava.
STMX is a high-performance Common Lisp library for composable Software Transactional Memory (STM), a concurrency control mechanism aimed at making concurrent programming easier to write and understand. Instead of traditional lock-based programming, one programs with atomic memory transactions: if a memory transaction returns normally it is committed. If it signals an error, it is rolled back. Transactions can safely run in parallel in different threads, are re-executed from the beginning in case of conflicts or if consistent reads cannot be guaranteed, and effects of a transaction are not visible from other threads until committed. This gives freedom from deadlocks, automatic rollback on failure, and aims to resolve the tension between granularity and concurrency.
gpfcalc is a GTK+ front-end for pfcalc, a pipe friction calculator using the Darcy-Weisbach equation. It computes major, minor, and static losses for flow through pipes or ducts. Up to 1024 pipes or ducts can be defined by specifying hydraulic diameter, length, roughness, flow rate, temperature, and elevation change. Data can be saved in a comma separated values file (CSV) and imported in the spreadsheet program of your choice for further processing.
Alore is an object-oriented programming language with a clean syntax that resembles Python and Lua. It is optionally-typed like Google Dart. It is both a dynamic scripting language and a general-purpose language with static typing. It is aimed at most programming tasks, from short scripts to complex applications. It allows programmers to freely mix static and dynamic typing within a program. It has native threads and a very fast edit-test cycle. Programmers can always bypass type checking and run their programs immediately.
