Flashrom is a utility for reading, writing, erasing, and verifying flash ROM chips. It's often used to flash BIOS/coreboot/firmware/EFI images. It supports a wide range of DIP32, PLCC32, DIP8, SO8/SOIC8, and TSOP32/40/48 chips, which use various protocols such as LPC, FWH, parallel flash, or SPI. The tool can be used to flash BIOS/firmware images, for example, be it proprietary BIOS images or coreboot (previously known as LinuxBIOS) images. It can also be used to read the current existing BIOS/firmware from a flash chip.
Consh is a set of programs that can turn one or more UNIX hosts on a trusted LAN into a singular Bourne shell multi-computer on which shell scripts are run concurrently. The service abstracts hosts into what appears to be shell process with a fixed number of threads or workers, to which work may be assigned and results received concurrently. It includes utilities that assign commands to workers in parallel and a command that initiates distributed barriers between workers for synchronization purposes. Environment variables can be set on a per-host basis to implement locking mechanisms like semaphores or ticket algorithms. Daemons can delegate work to one another as needed.
BurnerOnFire is a multi-threaded program that can write the same content to multiple CD/DVD burners simultaneously. It is currently developed and tested only on Debian and only supports content in the form of ISO files. It uses D-Bus/HAL specification to interact with hardware. It spawns subprocesses that wrap around the command line program Wodim. BurnerOnFire has both CLI and GUI (GTK+) interfaces.
The Crossplex package of make macros simplifies the creation of embedded systems, and is powerful enough for large organizations to use for developing elaborate product lines. It allows you to organize many different products under a logical structure, making systems of any complexity easy to specify. When you have many different target platforms, each with multiple different software configurations, Crossplex keeps those configurations from stepping on each other, without requiring redundancy in your source tree. Crossplex allows you to use a single dependency tree encompassing both in-house software and third-party packages, and it is particularly suited to build automation. Crossplex makes it easy to shield your build from the host environment, setting all shell variables explicitly, and giving you complete control over the path that is used at any point in the build. This is nice when you want to support building on a variety of development platforms. Crossplex scales to your needs. You can dabble in the unpacking and patching features as you need them, or you can base your entire system from the ground up on the Crossplex framework. Crossplex supports creation and use of glibc and uClibc toolchains.
Multicrush is a wrapper around pngcrush that distributes the work of brute-force compressing a single image over several pngcrush processes. This gets you a slightly less than a linear speedup, caused by different compression methods having slightly different durations. For example, the author has measured a speedup of 1.92 on a 2-core Intel T5300, and 3.86 on a 4-core Intel Q6600. The only requirements are a copy of pngcrush and at least Python 2.4. If you have version 2.6 or higher, multicrush can automatically detect how many CPUs to use.
Charm++ is a portable adaptive runtime system for parallel applications. Application developers create an object-based decomposition of the problem of interest, and the runtime system manages issues of communication, mapping, load balancing, fault tolerance, and more. Sequential code implementing the methods of these parallel objects is written in C++. Calls to libraries in C++, C, and Fortran are common and straightforward. Charm++ is portable across individual workstations, clusters, accelerators (Cell SPEs and GPUs), and supercomputers such as those sold by IBM (Blue Gene, POWER) and Cray (XT3/4/5/6). Applications based on Charm++ are used on at least 5 of the 20 most powerful computers in the world.
OpenMPF is a library for solving large, dense, multi-RHS linear systems. It is based on MPI/openMP parallelism, and relies on BLAS/LAPACK/MUMPS for the single node computations. It implements direct and iterative solvers, out-of-core matrices and vectors, and is easily accessible through a Python interface.
