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.
Opendedup is a deduplication-based filesystem and block device designed to provide inline deduplication and flexiblity for applications. It benefits services such as backup, archiving, NAS storage, and Virtual Machine primary and secondary storage, and can be deployed in both a stand alone and distributed, multi node configuration. Standalone, it provides inline deduplication, replication, and unlimited snapshot capabilities. In a multi-node configuration, it adds global intra-volume deduplication, block storage redundancy, and block storage expandability. and will store and share unique data blocks with other volumes within the cluster. These volumes can also specify a level of redundancy for data stored in the cluster.
