--disable-time-profile option

[malwi]

Dear Yambo Team,

we got an error "too many clocks" at the very end of the optical calculations for a very large system.
The files in LOG showed that 100% was done and job's predicted time was approaching.

Then we found
viewtopic.php?t=1569:
and
"one easy solution should be to re-compile yambo with --disable-time-profile option given when running the configure."

Is the proposed compilation better than the one with "time-profile"? What is the difference?
Shall we use it always for all calculations?

Best regards,

Dear Małgorzata Wierzbowska,

Is the proposed compilation better than the one with "time-profile"? What is the difference?

Without, the code does not check the timing needed for the different steps of the calculations, e.g. you will not get a report of the timing at the end of the simulation.
You still get the "live timing bars" which mark the progression of the simulation.
This should not have an impact on the duration of the simulation.

Shall we use it always for all calculations?

By default it is enables and it should be safe. However in very few cases it can give issues, and it is better to disable the "time profiling"

Best,
D.
