Re: On intended use cases of the distributed annex

I used the DSA quite regularly and recently, but the job was not as complex as this. However I do know of a guy working at the french nuclear research institute who made a stack of PC's do some heavy computation using the DSA to break apart the computation job and put it back together using asynchronous messaging. It was quite a feat!

My impression from hearsay is that the DSA allows one to define a structure of nodes, and that you program as if this was a single entity, and the remote interactions are done for you. What I'm not sure of is if it supports, for example, is things like "allocate as many nodes as online machines", node migrations and things like that. Or, things like resilience through redundant nodes.
