Hi Andrew, A couple of observations from a demo of the 0.1rc5 version of PCEnv (using a Fedora Core 6 laptop).
* I loaded up pcenv, ran a simulation and plotted the results - all worked fine. Then I exited the pcenv GUI and started it up again, as expected the model was still in the model tree but although the model was "locked" and I was unable to change anything about it I could not draw the graphs. I'm guessing that is caused by the simulation results being stored in the pcenv GUI not the cellml_corba_server, so the model should probably be unlocked in the cellml_corba_server once the GUI exits. * Also, in the same run with pcenv, it started behaving pretty intermittently until I quit and killed the cellml_corba_server process. It was very slow to load a model and never really became interactive after the model loaded. * With a fresh start I was able to load up the model I wanted (with the usual and prolonged delay as the GUI populated itself), and run the integration which was pretty much instantaneous (very good!). I could then draw all sorts of graphs using two of the graphing windows. I then loaded up an almost identical model which eventually came up fine, but when I tried to integrate that model it took a huge amount of time to complete the integration (i.e., more than 5 minutes). The interface was still usable during this time and I was able to go back to drawing graphs of the first model and had given up on the second model by the time it finally finished its integration. I was then able to plot the two models together. Not sure why the second model took so long to integrate given the first model which integrated almost instantaneously has one equation different (algebraic not an ODE) and the load on the machine hadn't changed...

Subject: [cellml-discussion] PCEnv 0.1rc5 (release candidate for PCEnv 0.1)out Hi all, The fifth release candidate for PCEnv, version 0.1, has been released. Information about the released files is available at: http://www.cellml.org/downloads/pcenv/releases/0.1rc5 Note that this release does not introduce any source code changes, but the shipped binaries now include CellML API 0.1rc5 instead of 0.1rc4 (this corrects a bug found 0.1rc4 by David Nickerson which can cause crashes on some invalid CellML models). This release candidate has been designed so it will work with the recent xpcellml_api 1.0 release candidate (xpcellml_api 1.0rc2). If you are interested in using PCEnv 0.1, please test this release candidate to ensure there are no problems with it. Once a reasonable amount of time has elapsed, and no problems with the release candidate are identified, PCEnv will be released. Please report any bugs you find at http://www.cellml.org/tools/pcenv/tracker, or to this list, or directly to [EMAIL PROTECTED] Best regards, Andrew Miller _______________________________________________ cellml-discussion mailing list [email protected] http://www.cellml.org/mailman/listinfo/cellml-discussion
