ReactOS is an advanced operating system providing a ground-up implementation of a Microsoft Windows XP/Windows Server 2003-compatible operating system. It aims to achieve complete binary compatibility with both applications and device drivers meant for XP and NT 5.2 operating systems by using a similar architecture and providing a complete and equivalent public interface. Written completely from scratch, ReactOS is not a Linux based system, and shares none of the UNIX architecture.
Bandwidth is primarily a memory bandwidth benchmark, but it can also measure network bandwidth. It measures the maximum memory bandwidth of each part of the memory system, including main memory, L1, L2, and L3 caches, framebuffer memory, and register-to-register. For many tests, it performs both sequential memory accesses as well as random memory accesses to provide a more real-world performance estimate. The tests support Linux (Intel), Windows/Cygwin, and Mac OS X. Its core routines are in assembly for x86 and x86-64 architectures with both SSE4 and AVX support. Bandwidth also includes automatic graphing of the results, stored to a BMP image file. The network bandwidth tests support Linux, Mac OS X, and Windows/Cygwin.
FastFlow is a pattern-based programming framework targeting streaming applications. It implements pipeline, farm, divide and conquer, and their composition, as well as generic streaming networks. It is specifically designed to support the development and the seamless porting of existing applications on multi-core. The layered template-based C++ design ensures flexibility and extendibility. Its lock-free/fence-free run-time support minimizes cache invalidation traffic and enforces the development of high-performance (high-throughput, low-latency) scalable applications. It has been proven faster than TBB, OpenMP, and Cilk on several micro-benchmarcks and real-world applications, especially when dealing with fine-grained parallelism and high-throughput applications.
Excelsior JET is a Java VM enhanced with an Ahead-Of-Time (AOT) compiler and deployment toolkit. It is certified Java Compatible on Windows and Linux on Intel x86 hardware. The 64-bit version is in the works. Excelsior JET Optimizer transforms your classes and JARs into high-performance binary executables. Excelsior JET Runtime includes a licensed Sun implementation of the Java API and Excelsior's proprietary JVM, which is responsible for Java memory management, threading, synchronization, security, and JIT compilation of classes that could not be precompiled. The Excelsior JET Installation Toolkit makes it possible to prepare your optimized application for deployment to end-user systems.
GAG is a Graphical Boot Manager with a lot of features. It doesn't need a partition, it works with primary and extended partitions in every hard disk, it has a lot of icons, it allows you to put passwords for each operating system, it can swap hard disks and it can be tested from diskette. The SafeBoot feature allows you to boot your hard disk even if GAG is overwritten. It includes extensive support for many languages and keyboard types.
libjpeg-turbo is a high-speed version of libjpeg for x86 and x86-64 processors. It uses SIMD instructions (MMX, SSE, SSE2) to accelerate baseline JPEG compression and decompression. libjpeg-turbo is generally 2-4 times as fast as the unmodified version of libjpeg. It also includes a wrapper library for the TurboJPEG API used by VirtualGL and TurboVNC. It was originally based on libjpeg/SIMD but has improved support for Mac OS X, 64-bit platforms, 32-bit and big endian pixel formats (RGBA/BGRA/ABGR/ARGB), accelerated Huffman encoding/decoding, and various other fixes.
XBMC Media Center (formerly Xbox Media Center) is a multimedia player/jukebox application for Linux, Mac OS X, Windows, and Xbox. It can be used to play or view most common video, audio, and picture formats such as MPEG-1/2/4, DivX, XviD, MP3, AAC, JPG, and GIF directly from a CD or DVD in the Xbox DVD-ROM drive or from the Xbox hard drive. XBMC can also stream files over a local network or from the Internet. Playlist and slideshow functions, a weather forecast, and many audio visualizations are also included.
HelenOS is a microkernel-based multiserver operating system designed from scratch. By decomposing the operating system functionality into tens of isolated but intensively communicating userspace servers, it provides a computing environment that has several virtues such as flexibility, increased robustness, well defined explicit interfaces, and smaller complexity of individual components. HelenOS does not aim to be another clone of Unix or some other legacy system and is not POSIX-compliant (even though it may seem POSIX-similar at times). Instead, the goal has been to design it according to what is the most elegant and right thing to do. What makes HelenOS unique among the other multiserver operating systems is its multiplatform and multiprocessor microkernel. It will run on seven different processor architectures ranging from a 32-bit uniprocessor little-endian ARMv4 to a 64-bit multicore big-endian UltraSPARC T1.
