We are having some problems after compiling successfully the MMG library in some AMD processors ( and at least in one model of Intel i7), when trying to run some 3D examples with the MM3D we get an “Unexpected error”, we tried to use the GDB, but the memory stack is empty, son we don’t have any clue why this is happening.
I understand that is complicated to guess the origin of the problem, specially if can not replicate the experience. The only information we can give you is the computer model:
- https://hpc.cimne.upc.edu/portfolio-view/compute-nodes/ , the corresponding node is the Dell PowerEdge R815.
- A computer with AMD FX™-8300 Eight-Core Processor.
- The model of Intel i7 could not provide more information, we will inform you as soon as we can do it.
In all the cases we are using the last version (5.2.1) and compiling with the last version of GCC (6.2).
The only think I can think that it is related with some kind of instruction not compatible, But it is complicate to guess.
Thank you very much for your comprehension
