<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></blockquote><div><br></div><div>What version of CUDA do you have?
