Hi Ray, ok, then I will try to get the new CPLEX Version instead of deleting the clone file after each dcopf calculation.
Thank you for your help! Hans Von: [email protected] [mailto:[email protected]] Im Auftrag von [email protected] Gesendet: Donnerstag, 24.

Information on the "fix pack" can be found here<https://www.ibm.com/developerworks/community/forums/html/topic?id=3271fea9-42d8-407f-ae79-7d043fa850fa&ps=25>. I have confirmed that the clone1.log files are no longer created with CPLEX 12.6.0.1 if I add ... opt.output.clonelog = -1; ... at line 129 of cplex_options.m, which I have done for the next MATPOWER release. -- Ray Zimmerman Senior Research Associate B30 Warren Hall, Cornell University, Ithaca, NY 14853 USA phone: (607) 255-9645 On Jul 21, 2014, at 1:10 PM, Ray Zimmerman <[email protected]<mailto:[email protected]>> wrote: Unfortunately, unless I'm missing something, I don't think CPLEX offers a way to turn off the log file completely via the Matlab interface. I think the output.clonelog option just controls whether the logflie is cloned when using parallel computation. It's been bugging me too, but I haven't found a solution. I'll report back if I hear a response to this post<https://www.ibm.com/developerworks/community/forums/html/topic?id=57df051b-918b-45ac-a9ac-654edc22c2d8>.

Every time I call the dcopf, CPLEX creates a log-file called "clone1.log" and writes some solver-outputs in it. If the file already exists, CPLEX opens it and extend it with new output. Now I am trying to force CPLEX not to create this file, but unfortunately it´s not working. My CPLEX Version: 12.6.0 and 12.5.1 Here is how I tried: mpc = case3120sp; % Just an example opt1 = mpoption('OPF_ALG_DC', 500,'OUT_ALL',0,'CPLEX_OPT',1); [r,s] = rundcopf(mpc,opt1); +++++++ function opt = cplex_user_options_1(opt, mpopt) opt.output.clonelog=-1; +++++++ I would be very thankful is somebody can help me with this issue.
