Present: Peter, Steve, Roland, Erik, Josh, Matt, Philipp * Erik, Ian and Barry are working on simfactory 3 which modularizes simfactory and includes facilities to build ExternalLibraries outside of Cactus ** downloads source code of external libraries only when required ** contact Ian Hinder for access to source code ** Steve asked if the modules in simfactory would be useful as a basis to replace the main Cactus make file with a script ** Erik said that so far simfactory 3 treats Cactus as a black box
* Caltech would like to extend our EOS interface to handle more complex EOS that take an extra independent variable (describing the nuclear composition). ** it is suggested to leave the current EOS calls in place and to add a new set eg including Abar in the new function names ** possibly forward the "old" calls to the new ones, passing NULL for the extra argument ** Fortran callability may be sacrificed in the initial implementation * currently bluewaters shows a significant regression in run speed that even occurs when using an old executable. The seems possibly related to an update of the MPI stack. Philipp is working with Bluewaters support to fix this. Bluewaters is aware of the problem and Cactus is not the only code affected. Yours, Roland
