[CIG-SEISMO] SPECFEM3D: GPU memory usage limited

[Fehr, Moritz]

Hallo,

I have a problem simulating a CUBIT meshed model (1.000.000 elements) on a Tesla GPU V100-SXM2 (amazon cloud CPU / GPU cluster). I am using SPECEM3D Cartesian (V3.0) and the newest CUDA 9 lib. I want to share this issue: It seems that the GPU memory usage is limited to a value of 420 MiB although the maximum GPU memory is 16000 Mib.
Do you have any idea about the origin of this limitation?

Thanks
Mo
