[CIG-SEISMO] Error executing specfem3d with CUDA / GeForce GT 730

[Leandro Gazoni]

Hello everyone,

My name is Leandro Gazoni, I am a Phd student in computational mechanics in
Federal University of Rio de Janeiro / Brazil. I have done some studies on
using SprecFem3d I was able to compile, run and modify some examples using
MPI.

I would like to test the same problems with cuda but I have had problems
running the example: (/ EXAMPLES / meshfem3D_examples / simple_model) with
a GPU: GeForce GT 730, 64bit card. Is it possible to run tests with this
board?

I can compile specfem3d without problems with ./configure --with-cuda, but
when running the example I have the following error:

born @ jobi: ~ / Downloads / specfem3d / EXAMPLES / meshfem3D_examples /
simple_model $ ./run_this_example.sh
running example: Thu May 3 05:06:59 -03 2018

   setting up example ...

   running mesher ...

   running database generation ...

   running solver ...

Error in setConst_hprime_xx: invalid device symbol
The problem is maybe -arch sm_13 instead of -arch sm_11 in the Makefile,
please doublecheck

Leandro Gazoni
