can't open dependency file
 
Pace's post processing failed with the following log file tail. What should we do next?

You may want to restart with -ncr switch, because it is not done yet
(dim = 10492215 but should be around 1302037[B][I]5[/I][/B] to finish).
First check if there's a *.chk file in that directory...
In any case, back up the data before continuing.

What processor was this running on? The cache size reported is quite small, so maybe there's an L3 cache that was not detected properly. I have to fix the code every year or so to recognize new cache codes. Getting the size right can double the performance.

Same issue here, trying your approach.

Still with problems.

If there are no dependencies, there will be no .dep file written.
Last time, there was an early abort (which is likely when CPU+memory+m/b memory lanes are not flawless.)

In your new case, the reason is different: lanczos halt was at the proper "end of the road" but you are getting only trivial deps. And this will not change by restarting from .chk file.
