Hello,

I am getting segmentation faults on PAW calculations just after the SCF converges. Here is the message that comes up on running the first PAW tutorial:

Code: Select all

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Backtrace for this error:

I've tried different PAW runs and psps, but they all seem to break like this. I am using Ubuntu 18.10 on a 64 bit PC.

Cheers,

Jim

Dear Jim,
Without more info about the calculation you are doing (input/output is welcome, also send what the command "abinit -b" is returning regarding compilations flags/options, etc ) it'll be impossible to help you.
Best wishes,
Eric

Dear Eric,

My apologies, input, output and configuration details are attached. This is the standard PAW tutorial file that comes with Abinit, so it should run fine. I've tried some of the other PAW-related files and different PSPs, and it gives the same error.

Many thanks,

Jim

Dear Jim,
Indeed, I've tested it on my machine and everything goes fine...
Did you check if your compilation passes most of the automatic tests (by going into the tests folder and run ./runtests.py j=number of CPU)?
On which architecture are you running Abinit?
Best wishes,
Eric

Hi Eric,

I am on a 64 bit x86 laptop running Ubintu 18.10. Abinit was compiled with gcc/gfortran 8.2. I ran the fast tests with "make test" after compiling but not the full runtest.py yet.

Cheers,

Jim

Hi Jim,
OK and did you try to run all the tests? It is surprising that the make test works and not a run from tutorial...
Best wishes,
Eric
