<br>
I am trying to run PETSc (with complex numbers in the GPU).
When I call <br>
the VecWAXPY routine using the complex version of PETSc and
mpicuda <br>
vectors, the program fails with a segmentation fault. This
problem does <br>
not appear, if I run the complex version with mpi vectors or
with the <br>
real version using mpicuda vectors. Is there any problem
using <br>
CUDA+complex PETSc?<br>
<br>
Furthermore, I use the -log_view option to run the
complex+gpu code, <br>
otherwise the program fails at the beggining.<br>

<div>What version of CUDA do you have? There are bugs in the
versions before 10.2.</div>
