I think Jon listed out what we normally specify for cmake when installing Trilinos to work with FiPy. I don't worry about the quantity of packages installed. I think the duration of the installation is much more concerning and I don't believe that it is that long for Trilinos anymore. Last time I installed Trilinos it didn't feel that long probably less than an hour. FiPy only uses two packages in Trilinos, I believe, but it really isn't worth setting up the cmake script to optimize this. Something will just go wrong and you'll spend hours debugging it. There are all sorts of dependencies within Trilinos so there isn't much point optimizing unless you really know Trilinos well IMO. -- Daniel Wheeler _______________________________________________ fipy mailing list fipy@nist.gov http://www.ctcms.nist.gov/fipy [ NIST internal ONLY: https://email.nist.gov/mailman/listinfo/fipy ]
