I just downloaded a Gromacs p2106. Below is a copy of my log. I keep getting the "timered checkpoint triggerd" entry. It doesn't seem to be processing beyond step 48790. Would you know anything about this. I've done17 other units, and none has ever behaved like this one. Does the checkpoint message mean that there's no folding going on?

Would you please read my post number 152 and see if you know anything about "timered checkpoint triggered"?

Clara, checkpointing doesn't necessarily mean no folding is occuring. Do you have it set for 6 minutes?
It's entirely possible that you've got such a bear, and those 5waymelts are that it's taking a long time and checkpointing before hitting the next reporting step.
Every core reports slightly differently but a recent log for one of those looks like this to me.

Notice, it's 22 minutes for 100,000 steps. This is on an AMD 64 4000+ cpu with 2gb ram. In other words, it's a pretty hefty burden and if you're running much less CPU, you could take 2-3 times to finish the same unit and with checkpointing at 6 minutes, it's just reporting in.

The timered checkpoint is a backup save frequency that you can set in the configuration menu. It probably doesn't seem to have progressed in the log file because it is such a large job that it won't report the progress until probably 100,000 steps are completed. It's only been about 30 min in that log, I would give it another hour and check on it. My computer is running the corresponding p2107 job with 20,000,000 steps reporting every 200,000 steps in the log file about every 20 minutes. Your computer is saving the progress (see your beginning step value in the log file showing you'd restarted the program and it picked up folding that job at ~49,000) but just not displaying it to you.
These are whopping huge WU, mine won't wrap up for at least 3 more days.

I also noticed something mine reports that your's does not.
[15:33:25] Extra SSE boost OK.
What CPU are you running? If it doesn't have SSE or it's disabled for some reason(can occur if a protein errors out), completion times are going to be much longer than my 22 minutes.
