I have found the reason of high usage of cpu. The user guide of kepler missed some details about the addition sample, so after I build a model as it said, the usage of cpu is very high. Fortunately, I found it's a paramter about iteration in sdf director cause the problem, the default value of it is 0. After I change the value to 1, everything is fine.
Thank you very much! ---------------- Best Regards, Kun Xiao -----Original Message----- From: Dan Higgins [mailto:[email protected]] Sent: 2006?9?28? 13:52 To: Efrat Frank Cc: Kun Xiao; Kepler-users at ecoinformatics.org Subject: Re: [kepler-users] Kepler-users at ecoinformatics.org I downloaded a new copy of Kepler-1.0.0beta1 (with jre), installed it, and also ran it with no problem, so I see no evidence of a memory leak. I have 2GB of memory, but the Windows Task manger reports that only a bout 520 MB is being used when I am running Kepler. So I have no idea why you are having the reported problem! The only thing I can suggest is perhaps your download was corrupted, so you might try downloading the installer again and reinstalling?
