Revactor’s TCP sockets API is virtually identical to Ruby’s, meaning that porting programs from Ruby to Revactor is a snap. While underneath it achieves high scalability by using non-blocking I/O, Actors can make blocking calls to read and write from sockets, or even make entire HTTP requests and read responses.

GPU

CUDA: CUDA (originally Compute Unified Device Architecture although this is no longer used) is a parallel computing architecture developed by NVIDIA. Simply put, CUDA is the compute engine in NVIDIA graphics processing units or GPUs, that is accessible to software developers through industry standard programming languages.

OpenCL: OpenCL (Open Computing Language) is a framework for writing programs that execute across heterogeneous platforms consisting of CPUs, GPUs, and other processors. OpenCL includes a language (based on C99) for writing kernels (functions that execute on OpenCL devices), plus APIs that are used to define and then control the heterogeneous platform. OpenCL provides parallel programming using both task-based and data-based parallelism.

BrookGPU: Brook for GPUs is a compiler and runtime implementation of the Brook stream program language for modern graphics hardware.

Mac OS X

MacResearch: Site dedicated to performing research on Mac OS X.

Velocity Engine: The Velocity Engine, embodied in the G4 and G5 processors, expands the current PowerPC architecture through addition of a 128-bit vector execution unit that operates concurrently with existing integer and floating-point units. This provides for highly parallel operations, allowing for simultaneous execution of up to 16 operations in a single clock cycle. This new approach expands the processor’s capabilities to concurrently address high-bandwidth data processing (such as streaming video) and the algorithmic intensive computations which today are handled off-chip by other devices, such as graphics, audio, and modem functions.The AltiVec instruction set allows operation on multiple bits within the 128-bit wide registers. This combination of new instructions, operation in parallel on multiple bits, and wider registers, provide speed enhancements of up to 30x on operations that are common in media processing.

VAST/AltiVec: With the advent of the Motorola G4 and IBM G5 chips featuring the AltiVec unit (Apple calls it the Velocity Engine) you can now achieve very high performance from desktop systems. Vector processing techniques from supercomputers have made their way down to microprocessors, and if you adapt your application to take advantage of these vectors, you can see dramatic performance gains. VAST is a code optimizer that has been widely used for over 20 years to help people get the most out of high performance computer systems. It features highly advanced automatic vectorization and parallelization. VAST analyzes source codes and creates a new version of the program that includes vector and/or parallel constructs and runs faster than the original program.

 

Cloud Computing

Eucalyptus: EUCALYPTUS - Elastic Utility Computing Architecture for Linking Your Programs To Useful Systems - is an open-source software infrastructure for implementing “cloud computing” on clusters. The current interface to EUCALYPTUS is compatible with Amazon’s EC2 interface, but the infrastructure is designed to support multiple client-side interfaces. EUCALYPTUS is implemented using commonly available Linux tools and basic Web-service technologies making it easy to install and maintain.

Databases

PostgreSQL: PostgreSQL is a powerful, open source object-relational database system. It has more than 15 years of active development and a proven architecture that has earned it a strong reputation for reliability, data integrity, and correctness. It runs on all major operating systems, including Linux, UNIX (AIX, BSD, HP-UX, SGI IRIX, Mac OS X, Solaris, Tru64), and Windows. It is fully ACID compliant, has full support for foreign keys, joins, views, triggers, and stored procedures (in multiple languages). It includes most SQL92 and SQL99 data types, including INTEGER, NUMERIC, BOOLEAN, CHAR, VARCHAR, DATE, INTERVAL, and TIMESTAMP. It also supports storage of binary large objects, including pictures, sounds, or video.
