You'll probably want to read the paper describing what kinds of computer
topologies you can use with Alchemi
http://www.gridbus.org/papers/Alchemi.pdf
I'd suggest [a] of Figure 3.
So you'll need to have
- 1 Manager node. This computer will need to have a SQL server running on
it. I got mine to work with Microsoft SQL Server Express 2005 (free)
without any problems.
- As many Executor nodes (computers) as possible. So start hunting around
for unused computers and try to get as many as you can. You'll need to
install the Alchemi Executor on each of them, and tell them to connect to
the Manager that you set up.
Those are the hardware requirements. Then you'll need to make sure that the
grid works. The example available on Sourceforge are a good place to
start. I just looked at the Pi calculator example, and it was pretty
straightforward from there to write my own GThreads to do what I wanted them
to do. There is also an example in that paper. I wrote mine in C# with
Visual Studio 2005. When you run your application, it will submit your
GThreads to the Manager, which then get distributed to the Executors, which
run the threads and return the results back to the Manager, which returns
them back to you.
I think there was a tutorial PDF on the alchemi.net site, but it's down. I
think that PDF is available in the SDK download on Sourcefore as well, but
I'm not certain.
Good luck,

Hi all,
I am Hanumanth an M.tech student.As my M.tech project i am verymuch
interested in doing a project on Grid computing.
As the main aim of grid computing is it enables the sharing, selection, &
aggregation of geographically distributed "autonomous" resources depending
on their availability, capability, cost, and user QoS requirements.
I need to know how to connect two or more systems in grid using alchemi.
and
I am having one large application. To build that particular
application in
a single system it is taking 3 hours of time.so I want to build that
particular application in Grid environment in lessthan 3 hours of time.
I request all the alchemi users to just give me an idea how to follow.
Thanks & Regards,
