Dapper Dataflow Engine 0.92 (Default branch)
Image Dapper, or "Distributed and Parallel Program Execution Runtime", is a tool for taming the complexities of developing for large-scale cloud and grid computing, enabling the user to create distributed computations from the essentials: the code that will execute, along with a dataflow graph description. It supports rich execution semantics, carefree deployment, a robust control protocol, modification of the dataflow graph at runtime, and an intuitive user interface. License: GNU Lesser General Public License (LGPL) Changes:
On the fly generation and aliasing of dataflow graph edges are now possible. The API has been simplified, and redundant interfaces have been done away with; at the same time, dataflow graphs are now robust to tampering from malicious users. The concept of execution domain has been introduced to control what executes where. The manual is now substantially complete, and has been updated with a bevy of examples and diagrams. The SourceForge mailing lists dapper-user and dapper-announce have been created.Image

NAME

       xcp-xapi - XCP's XenAPI server

DESCRIPTION

       The  Xen  Cloud	Platform  (XCP)  is an open source enterprise-ready server virtualization and cloud computing platform, with support for a
       range of guest operating systems, Linux network and storage support.

       XCP addresses the needs of cloud providers, hosting services and data centers by combining the isolation and multitenancy  capabilities	of
       the  Xen  hypervisor  with enhanced security, storage and network virtualization technologies to offer a rich set of virtual infrastructure
       cloud services. The platform also address user requirements for security, availability, performance and isolation across both  private  and
       public clouds.

       XCP  consolidates  server  workloads, enables savings in power, cooling, and management costs and thus contributing to environmentally sus-
       tainable computing, an increased ability to adapt to ever-changing IT environments, an optimized use of existing hardware, and an  improved
       level of IT reliability.

       This  is  the XenAPI server, which provides the control plane for XCP hosts and resource pools. To manage the XenAPI server, you should use
       either the XML-RPC based API, the xe command line tool, or a graphical user interface such as OpenXenManager.
