[Wien] lapwsopara error

maybe this helps

from Wikipedia
In computing, a bus error is a fault raised by hardware, notifying an operating system (OS) that a process is trying to access memory that the CPU cannot physically address: an invalid address for the address bus, hence the name. In modern use on most architectures these are much rarer than segmentation faults, which occur primarily due to memory access violations: problems in the logical address or permissions.

more is found from google

Betreff: Re: [Wien] lapwsopara error

Hi Gavin,


You are right, there are .timeso files (but no .stdoutso) for each k-point and the ones that fail to complete

have an error message:


-cn0130 Bus error

Considering that this error occurs due to a specific choice of spin direction, can it be due to software bug?


Thanks,
Fhokrul

For example, in the lapwsopara_lapw file on line 292 there is

 >& .stdoutso_$loop

and on line 297 there is

 >>.timeso_$loop

So, some errors that occur might be redirected into these dot files
(which are usually hidden unless ls -a is used or show hidden is
selected in a graphic file manager [
http://askubuntu.com/questions/94780/what-are-dot-files ]).  So if you

What are dot-files? - Ask Ubuntu<http://askubuntu.com/questions/94780/what-are-dot-files>

I am having a hard time grasping what dot-files are or what they are for. Are they directories? How do I navigate to them? Thank you!



haven't already done so, I suggest also checking the .timeso_* and
.stdoutso_* files if they exist.
