Newbie or Not Newbie, that is the question...

I have been crunching numbers for several years. I have had nothing but problems with my upgrade to El Capitan and have lost all my logins and passwords. I have a log book for websites but have received messages that the logins and pw listed cannot be found. I am very puzzled by this message, but was wondering if any one person can help me rebuild what I have done in the past? If not so be it, but it would be nice. I think I have three accounts from different times.

I have a general idea of what is going on, but not really. If there is ever a seminar about it I\'d love to know about it so I might attend. I think it is a good use of my processors time.

If your WU runtime preference is low (<4hrs) you will frequently see the progress % jump from 1.xx to 100%, or into the 50% range. Basically, each different protein takes a different time to crunch a model. Some proteins will crunch for several hours to complete a single model. Others will crunch a model every 5 or 10 minutes.
Thanks

Can I suggest that the \'system requirements\' section of the home page is updated. Hopefully no-one is using Windows XP any more.

Rosetta@Home must be using the Ghetto Credit System. Credits granted are extremely low.

Is there a simple way to prepare BOINC for a computer shutdown on a desktop? I guess I can schedule it to stop all computations by a certain time. If I shut down while it's working will my progress be lost?

Ideally, BOINC would be shutdown by right clicking the icon and selecting "exit", prior to shutting down Windows. But it is not required.

Some amount of work is lost. It is anything that has been done since the last checkpoint the task was able to store. You can get a sense for how much that is by looking at the properties for specific tasks, and comparing the "CPU time at last checkpoint" with the "CPU time". Rosetta tasks take a checkpoint after each model completed, and some types of tasks take checkpoints within models as well. So, typically, you should only be losing about 10 minutes of work per active task.
