Currently I either manually perform the launche= s of different lots, or leverage a cluster managed with Condor [1] at my in= stitution, but using C code. I was thinking about the possibility of requesting the installation of an A= da compiler in such cluster, and also if the DSA can fulfill my needs. I gu= ess I could dig into the docs but probably some of you know some pitfalls t= hat could elude me. My question is: is the DSA well-suited for load balancing distribution, eve= n if it is of simple nature. My impression from hearsay is that the DSA all= ows 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 no= t 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. In other words, does the DSA support reconfiguration (even if it is at laun= ch time) of nodes without editing a config file, or even online reconfigura= tion without manual intervention?=20 Thank you in advance,=20 Alex.
