crash in mod_timing.f90

Dear yambo developers,
I am experiencing yambo crash with the following error message:
Code: Select all
At line 229 of file mod_timing.f90
Fortran runtime error: Unexpected element '*' in format
(a,**x,a)
^
I think this might be related with the nodes numbering which in that case
goes in parallel over 100. From the last hint in the "l-*" output file I can deduce that some
nodes "**" finished calculations:
<12h-06m-36s> P**: G0W0 PPA |####################| [100%] 12h-05m-46s(E) 12h-05m-46s(X)
Thank you in advance for any hints.
Best regards,

Dear Martin,
what version of Yambo are you using?
Anyway the problem looks related as you say to the format. You can try to substitute the i2.2 in the mode_timing module
with i3.3. May someone else can give you a better workaround.
Cheers,
Daniele

Dear Daniele,
Thanks for your replay. I am running devel version, revision 48.
In the mod_timing.f90 there are several hash hints, and I am not sure
If I am able to change all of them consistently.
Best,

Dear Daniele,
Thanks for the update. It seems that job successfully restarted. I have a small request,
could you also implement the change to src/io/Fragments_Restart.F file as we discussed
in
viewtopic.php?f=10&t=701 post?
Thanks for your help,

I am sorry! I have been too fast. The error
Code: Select all
At line 229 of file mod_timing.f90
Fortran runtime error: Unexpected element '*' in format
(a,**x,a)
^
is still there!

This is strange. Did you do a
first ? With how many cpu are you trying to run ? Can you run with few cpu's ?

Yes, I did clean_all, recompiled yambo from scratch and run using 80 cores.
Job restarted, completed several thousands of sections and crashed after
five hours.

Is it the crash still related to mod_timing ? If yes can you provide all relevant input files (GS and Yambo) ? But we need first to reproduce the error with a smaller run. Can you try to reduce the parameters as much as possible in order to reproduce the error ?

Dear all,
Finally I have realized that troubles were due to interrupted y2p run (walltime limit on cluster).
Continuation somehow provides ill databases. Redoing databases from scratch I have been
able successfully finish the calculations.
Thanks for your participation,
