Aorta is a load-balancing clustered P2P application. It executes Tasklets (which have the ability to split themselves into sub tasks that can be executed in pararell). A typical cluster contains of a LAN with 1-256 computers, each one running aorta. A Tasklet can be of any type ranging from encoding MP3s, Genomic DNA Alignment, or simply to rendering Web pages for high speed/heavily loaded Web sites. You can make functions calls to C/C++, applications like Matlab, etc.

The Application Switch sits between applications and service providers, allowing a central location for configuration instead of requiring the user to configure each application separately. The switch also allows mutliple services to be combined and appear as a single service to applications.
ACDK is a development framework with a similar target of Microsoft's .NET or Sun's ONE platform, but it uses C++ as a core implementation language. It implements the standard library packages, including acdk::lang, acdk::lang::reflect, acdk::util, acdk::io, acdk::text (including regexpr), acdk::net, acdk::sql, acdk::xml, and more. Flexible allocator/garbage collection, threading, and Unicode are implemented in the core of ACDK. Extensions make C++ objects available for reflection, serialization, aspect-oriented class attributes, and [D]ynamic [M] ethod [I]nvocation. This DMI acts as an universal object oriented call interface to connect C++ with scripting languages (Java, Perl, Tcl, Python, Lisp, Visual Basic, and VBScript) and standard component technologies (CORBA and COM).
Babel is an IDL-based language interoperability tool specific to engineering and scientific applications. It allows Fortran 77, Fortran 90, C, C++, Java, and Python to call each other in a single address space for maximum performance. Babel won a 2006 R&D 100 award from R&D Magazine.
Blackbird is the first enterprise service bus (ESB) for PHP developers. It provides a range of services, including managing configuration data, connections to message queues, databases, and other applications, and many more features. This makes it possible to very rapidly develop message-based applications and/or integration layers.
