Bug in the command line tools

[Khue Le]

Hello,

I tried today running this:

[opengm]/build/src/interfaces/commandline/double/opengm_min_sum  -a ADSal --maxIt 1000   -m tsu-gm.h5:gm -o results/tsu-gm.h5 -v  --timeout 180 --gaplimit 0.00001 --threads 1

I set the timeout to 3 minutes, but the process just keeps running forever. I'm using OpenGM 2.3.5 (I guess this is the latest stable release?).

Could you please check?

Thank you in advance!

Hi,

It seems that there is a serious bug.

[opengm]/build/src/interfaces/commandline/double/opengm_min_sum  -a ADSal --maxIt 1000   -m models/triplepoint4-plain-ring-inverse.h5:gm -o results/triplepoint4-plain-ring-inverse.h5 -p 100 -v  --timeout 180 --gaplimit 0.01--threads 1

Results:

Warning: Argument "memlogging" not set. Using default value: 1

Segmentation fault

I tried running ADSal on the benchmark and observed that it was able to solve only a (very) few instances. I just picked up some concrete instances to check and came up with the bug.

Could you please check? (Version 2.3.5.)

Thanks.

Hello,

I had the same problem with the timeout (v2.3.5), but other algorithms (DDSubgradient, SRMP, TRWS and CombiLP).

time opengm_min_sum -my.h5 --timeout 1 -a DDSubgradient

[warning etc]

real    0m3.876s
user    0m3.860s
sys    0m0.012s

time opengm_min_sum -m my.h5 --timeout 1 -a SRMP

[warnings etc]

real    0m1.335s
user    0m1.324s
sys    0m0.004s

time opengm_min_sum -m my.h5 --timeout 1 -a TRWS

[warnings etc]

real    0m1.734s
user    0m1.720s
sys    0m0.004s

time opengm_min_sum -m my.h5 --timeout 1 -a CombiLP --maxIt 100

[warning etc]

CPXPARAM_TimeLimit                               3600

[...]
(It seems CombiLP is not properly repassing the timeout parameter)

Any insight would be appreciated.

Best regards,
Francisco
