New subject: No output from DWA

23 Mar 2018

      By default, it is set false because it will slow down your simulation (very...) drastically.
If you want them, please set in your params:
MEASURE[Green Function] = 1

Hey,
I am now working with revision 7650 where DWA works fine. However I've found that there is no output from Green's function. Is there any reason why it doesn't work and should it work in more recent versions? Also, is there maybe even earlier version at which computing Green's function works?
Best regards,
Oskar

Hi,
If it helps I am having this error with revision 7699, but with 7698 the error does not occur ( I did not check systhematically all revisions >=7700 but I did not anyone that worked).
r7697 fails at cmake "add_subdirectory given source "imps" which is not an existing directory.”
it seems that several revisions below 7696 are working fine.
All in all r7699 seems to be place where the error has been introduced.
Best,
Mateusz Łącki

Hey Oskar,
Greetings,
Thank you for reporting the bug.
With ALPS/2.3.0-py2 on CentOS/7.4.1708 via Conda/4.3.30, I reproduced the bug via GDB.
Program received signal SIGSEGV, Segmentation fault.

Furthermore, via blame, I confirm that there are no recent changes to the DWA code.
If you need to use DWA immediately, you need to download an earlier ALPS binary package (I am pretty sure that DWA works perfectly in the 2.2 release branch.)
Meanwhile, I need to investigate into what breaks the code internally.
Kind regards,
Tamama

Dear all,
I have just installed ALPS via conda and faced an unexpected problem
with the tutorial dwa-01-bosons. While running the program tutorial1a.py
on my laptop after thermalization is finished I get a segmentation
fault. I changed the code a bit (see below) to run this tutorial on the
bigger machine on which there is ALPS also installed via conda. The
segmentation fault does not occur, however the program does not produce
any output files and the produced graph is empty.
I have also tried to run DWA with these parameters without python -
using input file, but this have also ended with a segmentation fault.
