ABINIT Discussion Forums

Dear:
When I performed the test/t41.file,there exits error as follows:

*** glibc detected *** free(): invalid pointer: 0x0000002a99d35010 ***
p0_15043: p4_error: interrupt SIGx: 6
forrtl: error (69): process interrupted (SIGINT)
rm_l_1_29792: (2.921875) net_send: could not write to fd=5, errno = 32
forrtl: error (69): process interrupted (SIGINT)
p0_15043: (5.964844) net_send: could not write to fd=4, errno = 32

What is the problem?

1) read the nettiquette in viewtopic.php?f=20&t=251
2) this is probably linked to your build of abinit and in particular p4_error probably means a parallelization error.

You really can't expect us to explain your crash on so little information...

I have tested paralell calculation in ./tests/tparal_1.in, but it stops at:

I do not kown why? In Below is part of my log file.

your code is segfaulting, but there's no way to tell why at this distance. These input files have run on dozens of reference architectures every night for years, so the problem is with your build, hardware, or you have modified the input file. Your compilers are quite old, but this should not be the problem.
- Check your parallel mpif90/mpicc is correctly compiled with the same versions of the compilers.
- Compile without optimizations or (first) run under a debugger:

* read the gdb manual or a howto

* mpirun -np 4 abinit < etc.etc.etc. > &

* top gives you the pid for the instances of abinit, then you can run

* gdb $ABINITPATH/abinit <pid1>

* inside gdb, type cont to continue execution, and see where it crashes.

Also, does it run sequentially?

Hi,

I am running into similar error and I am not able to figure out why my jobs are crashing. Any help will be greatly appreciated.

Requested basis set is non-standard
Compound shells will be simplified
There are 30 shells and 82 basis functions
A cutoff of 1.0D-12 yielded 442 shell pairs
There are 3388 function pairs ( 4202 Cartesian)
