Hello Pelle, I just rebuild a fresh install of SLIC from scratch, using the Qt libraries. The startup time seems to depend hugely on the geometry that you load. I seem to recall this has to do with loading the GDML and some of the verifications that go on when you load it. If you load the geometry: HPS-Proposal2014-v8-6pt6, which appears to not have all the flanges for the ECAL, then the startup time into interactive SLIC is about 20 seconds. On the other hand, the geometry: HPS-Proposal2014-v7-2pt2, takes forever to load. There may be ways to optimize the ECAL flange geometry in a way that it loads quicker when loading it from GDML. I know that the identical geometry loads in seconds with GEMC, where the geometry is rendered directly from instructions from a text file. I am a bit worried if we are leaving out carefully constructed geometry from version 8 because it loads slowly. This geometry is correct and was carefully constructed from the drawing by Holly, and I made some minor modifications to turn it into valid GDML. Perhaps one of our GEANT4 experts can comment on why the GDML loads so slowly?

My version kind of runs but takes for ever to start and looks like it’s really hanging when I try to get to the g4 prompt at startup. > > I run OS X 10.9.2. > > If you have a successful version running, what version and any special settings? > > /Pelle > > ######################################################################## > Use REPLY-ALL to reply to list > > To unsubscribe from the HPS-SOFTWARE list, click the following link: > https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=HPS-SOFTWARE&A=1 ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the HPS-SOFTWARE list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=HPS-SOFTWARE&A=1
