Hello Andrew,
the appended file test.mod is examples/threads/clustering.mod with
appended line
printf {t in T} "%d -> %d\n", t, pt[t];
Essentially the line prints out part of the generated problem.
The output on x86-64 ends with:
49 -> 608
50 -> 334
Model has been successfully processed
The output on ARMv7 ends with:
49 -> 852
50 -> 472
Model has been successfully processed
How can it be that the generated model differs depending on the CPU
architecture?
If I run
printf {1..10000} "%16.15f\n", Uniform01();
I get the same result on both architectures:
0.443241402972490
Model has been successfully generated
So it is not a problem in the random number generation.
If I remove all variables and constraints from appended test.mod I also
get the same result on both architectures.
Best regards
