I'm not sure if this is the right e-mail target, but I didn't see any alternatives (other than perhaps direct e-mails to Todd or Bob)... I have two quick questions on Kestrel, but first some background. First, we are working on a Kestrel-based solver interface for our open-source python-based AML modeling tool (Pyomo). Second, we are trying (or at least thinking about trying, assuming we first part (1) working) a Kestrel-based solver interface for our open-source stochastic programming solver (PySP). For the latter, we need a quadratic solver, as we are using progressive hedging. My first question: When I submit to kestrel using the AMPL/CBC solver interface, I am getting the following error: No stations available for solver kestrel:Cbc:AMPL. Solver administrator has been notified. Is this "routine", or is CBC down for an extended time? My second question: XpressMP appears to be in the web-based interface, but not via kestrel (unless I missed the name in the list returned by the kestrel interface). Is there a fundamental reason for this, or just a "has-yet-to-be-requested" issue? Any information is greatly appreciated. For what it's worth, getting the python plugin up+running - at least to the point of job submission - was a breeze!
