Realtime raytracer using SIMD on ARM, MIPS, PPC and x86
QuadRay engine is a realtime raytracing project aimed at full SIMD utilization on ARM, MIPS, Power and x86 architectures. The efficient use of SIMD is achieved by processing four rays at a time to match SIMD register width (hence the name). The rendering core of the engine is written on a unified SIMD assembler allowing single assembler code to be compatible with different processor architectures, thus reducing the need to maintain multiple parallel versions. At present, Intel SSE/SSE2/SSE4 and AVX/AVX2/AVX-512 (32/64-bit x86 ISAs), ARMv7 NEON/NEONv2, ARMv8 AArch32/AArch64 NEON (32/64-bit ARM ISAs), MIPS 32/64-bit r5/r6 MSA and Power 32/64-bit VMX/VSX (little/big-endian ISAs) are mostly implemented, although scalar improvements, horizontal reductions, wider SIMD vectors with zeroing/merging predicates in 3/4-operand instructions, are planned as extensions to current 2/3-operand SPMD-driven vertical SIMD ISA. See README file.
A multi-threading framework using a prime sieve to do work
mtsieve is a framework wrapped around primesieve to distribute prime numbers to worker classes to do work with those prime numbers. The "mt" means that it is multi-threaded. The "sieve" means that the framework is typically used to eliminate candidate terms with small from a set of numbers. The numbers remaining after using mtsieve can then be used by programs such as llr and pfgw to test those numbers for primality. Another usage could be to use those prime numbers to test each for a specific characteristic, such as whether it is a Wieferich or Wall-Sun-Sun number. The framework is portable to any OS running on x86-64 and supports GPUs.

SIMD macro assembler unified for ARM, MIPS, PPC and x86
UniSIMD assembler is a high-level C/C++ macro assembler framework unified across ARM, MIPS, Power and x86 architectures. It establishes a subset of both BASE and SIMD instruction sets with clearly defined common API, so that application logic can be written and maintained in one place without code replication. The assembler itself isn't a separate tool, but rather a collection of C/C++ header files, which applications need to include directly in order to use. At present, Intel SSE/SSE2/SSE4 and AVX/AVX2/AVX-512 (32/64-bit x86 ISAs), ARMv7 NEON/NEONv2, ARMv8 AArch32/AArch64 NEON (32/64-bit ARM ISAs), MIPS 32/64-bit r5/r6 MSA and Power 32/64-bit VMX/VSX (little/big-endian ISAs) are mostly implemented, although scalar improvements, horizontal reductions, wider SIMD vectors with zeroing/merging predicates in 3/4-operand instructions, are planned as extensions to current 2/3-operand SPMD-driven vertical SIMD ISA. See README file.

an ethernet-based file system for DOS
EtherDFS is an 'installable filesystem' TSR for DOS. It maps a drive from a remote computer (typically Linux-based) to a local drive letter, using raw ethernet frames to communicate. For years, I was using LapLink to transfer files between my various "retro" computers. It works, yes, but it's also annoyingly slow and requires constant attention. One day I thought, "Wouldn't it be amazing if all my PCs could share a common network drive, similarly to how NFS operates in the *nix world?". This day EtherDFS was born. I clearly didn't invent anything - the concept has been around almost as long as the first IBM PC, and several commercial products addressed that need in the past. I am not aware, however, of any free and open-source solution.

Linux kernel port for the ADI's Blackfin and future processors
Linux is a clone of the operating system Unix, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX and Single UNIX Specification compliance. Although the Blackfin architecture has been in the mainline kernel since 2.6.22 (May 2007), there are various fixes and patches applied locally that are not upstream. Please use the kernel from here - and treat it like any other distribution kernel. This is a sub project of the ADI Buildroot project. Please find the bug tracker, task tracker, mailing list, released files and news tools at http://sourceforge.net/projects/adi-buildroot/ .

Buildroot Linux distribution for ADI Blackfin and future processors.
Buildroot is a set of Makefiles and patches that makes it easy to generate a complete embedded Linux system. Buildroot can generate a kernel image, various libraries and applications in a root filesystem. Buildroot is useful mainly for people working with small or embedded systems, using various CPU architectures (x86, ARM, Blackfin, MIPS, PowerPC, etc.). It automates the building process of your embedded system and eases the cross-compilation process. If you're new to buildroot Linux, the first thing to do is check out the [documentation](http://docs.blackfin.uclinux.org/). This should help you get your development host PC set up, and get you compling your first Linux distribution from source.

Pattern-based multi/many-core parallel programming framework
FastFlow is a C/C++ programming framework supporting the development of pattern-based parallel programs on multi/many-core, GPUs and distributed platforms. FastFlow run-time is built upon non-blocking threads and lock-free queues. Thanks to its very efficient CAS-free communication/synchronization support (e.g. few clock cycles core-to-core latency), FastFlow effectively supports the exploitation of fine grain parallelism, e.g. parallel codes managing very high frequency streams on commodity multi-core. FastFlow works on x86, x86_64, PPC, ARM, and Linux, Mac and Win XP/7. From Jan 1, 2018 code development migrated on GitHub at https://github.com/fastflow/fastflow
