Alchemi - Plug & Play Desktop Grid Computing

Alchemi is an open source software framework that allows you to painlessly aggregate the computing power of networked machines into a virtual supercomputer (desktop grid) and to develop applications to run on the grid.

It has been designed with the primary goal of being easy to use without sacrificing power and flexibility.

Alchemi includes:
  • The runtime machinery (Windows executables) to construct computational grids.
  • A .NET API and tools to develop .NET grid applications and grid-enable legacy applications.


Since 2006, Melbourne GRIDS/CLOUDS Lab team has been working on a new plaform for Grid and Cloud computing, called Aneka. This is a successor of Alchemi. Those interested in new Aneka software, please visit Manjrasoft website for details and you can also download Aneka software.

[Note: From now on (Aug 23 2006) all important news items related to software releases will appear only at the Alchemi project page at Sourceforge.]

September 9, 2004
The Alchemi BLAST sample is now available.

Searching for similarities between biological sequences is the principal means by which bioinformatics contributes to our understanding of biology. Of the various informatics tools developed to accomplish this task, the most widely used is BLAST. This sample contains a a grid-enabled version of NCBI BLAST for Alchemi and documents the technique used for grid-enablement.

  • Simple installation via Windows installers.
  • Machines can be on a LAN or the Internet.
  • Machines can be behind firewalls and NAT servers.
  • Only idle CPU time of machines on the grid is used; user programs are not impacted.
  • Object-oriented "grid thread" programming model for grid application development.
  • File-based "grid job" model for grid-enabling legacy applications.
  • Web services interface for interoperability with other grid middleware.
  • VS.NET design-time support (reusable WinForms components).
