Mutex Stored Procedure

Hi All, I want to create some distributed mutual exclusion using a database table. It would be nice to have the following interface on a stored procedure: Wait(uniqueidentifier) I was originally thinking of implementing this by having a table of unique identifiers.

Starting remote processes in a Windows network

I have several slave machines and a master machine which together run a distributed application. Processes on each slave machine have to have a GUI and network access (I think it would be called an interactive process then). For ease of use it would be nice if the master machine could start/stop the processes on those slave machines. My...

Framework for running distributed computations in .NET cloud

I'm thinking about developing a framework to simplify running distributed computations in .NET cloud environment of Windows Azure. Azure currently (and by the time of the release, most likely) is completely unsuited for simple running of distributed queries in the cloud (details).

Is Erlang designed only for running on a single multicore machine, or can you distribute the processes?

My app runs well on my quad-core machine. It is 'embarrasingly parallel', with about 100K processes, and thus nicely suited to run on a cluster of machines. However, I have trouble finding documentation on how to spread all those processes out on all available nodes in the cluster. The documentation for distributed Erlang seems to focus...

Speeding up build times in ASP.NET

I am currently involved in a ASP.NET project with about 40 projects in the solution. We are doing all our development in cloned Virtual PC environments so all developers have identical setups. That's all good, managing dependencies is easy, however building the solution is horribly slow. Virtual PC can only utilize one CPU so I'm really ...

Is it possible to set up a Linux box with distcc to build my XCode projects?

I have a mac mini on which I do some iphone and other experimental development. It is hideously slow to build some of the larger projects I have tried out (like 3d engines and such). There are some support for distributed builds with distcc and I have a quad core linux box just standing idle beside it. The question is: is it possible to...

Are there principles, guidelines, or best practices that wo...
