Hi everyone,
I'm running jobs with TMinuit that take 1-4 weeks to complete. I am finding that system instabilities can cause my machine's uptime to be less than the time required to finish the fit. It is *very frustrating* to wait a long time and end up with nothing.
I see that TMinuitOld purportedly has a method called mnsave that writes the intermediate fit results to file "in format which can be reread by Minuit for restarting". That sounds like exactly what I want to happen every few hours, but I cannot find the file TMinuitOld to write a version that does so.
Has anybody on this list put together a version of TMinuit that writes a journal-file and can restart a fit from said file? If not, does anybody have any advice for me as I try to write my own? I don't at this time know what variables TMinuit would need to save and recover, or if any other classes would also have to recover parameter values.
- John
