find_aperture throws SIGSEG

Hi,

i have not found any hint on how to get find_aperture working with Pelegant. Everytime i start my job, even this minimalistic attached one, the last line on the log is:

Code: Select all

Terminated by SIGSEGVProgram trace-back:
The process is still running on all cores, but there seems to be no progress. That's why i cancel that job.

Is there a work-around for this problem or is find_aperture not suitable for Pelegant or what am i doing wrong?


Thanks a lot

Julian

Julian,

The recommended mode for parallel elegant is "n-line", which works fine for parallel and serial modes. The code is actual *supposed* to exit with an error message when other modes are used, since they have not been parallelized.

By the way, you need not define a beam (&bunched_beam) for &find_aperture. It isn't related.

Thank you.
Now this works with mode="n-lines". I'm sorry for taking your time.

No problem. Sorry for the bug and lack of clarity in the documentation.
