Re: Conical Interaction Optimization Problem

Dear Panwang Zhou,

> TOO LITTLE TIME TO DO ANOTHER POINT, TIME USED=       169114.3
> TIMLIM GIVEN=       172800.0 NEXT POINT NEEDS=         4026.5 SECONDS

The job has stopped as next geometry search step would exhausted
the allotted CPU timelimit (which can be set or changed using the
$system timlim variable). Unfortunately, the stops due to exhausted
time limit are not always graceful while running in parallel mode and
can result in hangs. This is a known problem with no elegant fix.

You need to restart this job. From what I can deduce looking
at the part of output below it is very close to convergence.
Taking this into account I'd recommend to set both shift and
shift0 to 0.001 and set stage2 to .true.


Kind regards,
Alex Granovsky

>After 62 cycles, the firefly hang for over 4 days, no update to output file and firefly is stilling running, due to large size of output file, I haven't attached it and only paste the last lines in the following. It seems that everything is OK but the program said "THE NEXT PREDICTED SET OF COORDINATES FOLLOWS.  THEIR ENERGY AND GRADIENT IS UNKNOWN". What is the reason for this and how to fix it? Is it a bug for the hang of firefly?
