Running EPlus in the "Cloud" with distributed computing is definitely possible, if you are going to pay for the usage of the cloud service. EPlus is already in a private Cloud by running the on line simulation program.
I do not think any "Cloud" server or provider would let you run your own program with multiple users free of charge, or with the current Internet connection charge and without additional network access control. We are running on the left over cream of the Y2K bubble. Very soon the Internet capacity will not be free any more. VOIP, Face book, U-tube, etc. will not be free any more. I paid C$8.00 for 1GB of excess usage last month. It was because I had to accept free Microsoft up-date for Windows7, SP1, SP2 and all the .net, Office, Visual Studio, etc. When a large project is run in the Cloud, the connection cost would go up. The CD that is sold at a shop is just for the registration and the base software. It is not up-to-date. I cannot imagine that the Cloud providers would allow users to tap the Cloud CPU power for distributed computing without paying a fee. If it is on "when availaable" basis, then it may take un-known time to complete a job. I am already getting "loading" "sorry the service is not available" warnings on Hotmail on regular intervals. Please pay $29.99 annual fee, if you would prefer faster service and no commercials to cover the displayed message. There is large overhead control loaded with every Hotmail message. This is the reason why I was commenting that the public free Cloud computing may not be that wonderful for real production computing. Organisation whould build their own Cloud for their users by re-organizing and improving their current private LAN. Apps for Banking, looking up Chinese food, socializing, are not really "must have" services in the Cloud. When the cloud is not there, you can always pick up a phone. This is also the reason I do not want to give up by land line phone connection for the "home phone". When the unitility service is down, or the internet is down, the home phone is also not available. There are now public Cloud, private Cloud, etc. I think, the availability of Cloud computing and what is a Cloud are still very cloudy. ========================== "developing an energy optimization design tool by combining optimization algorithms with energyplus." This is great in principle. However, for real grobal energy saving design in buildings or other equipment, it is not a mathematical computational problem. It is an engineering and cultural problem.

Daniel, I'm definitely interested in hearing about your experience with EC2. I'm currently doing my thesis on developing an energy optimization design tool by combining optimization algorithms with energyplus. Given the number of simulation required I'm guessing cloud computing would be the only way to make it practical for commercial use. Im still on reaserch stage though, so not sure how plausible this is.
Best, Santiago.
