<body class='hmmessage'><div dir='ltr'>I am trying to use PETSc-dev for a while in a project at my university. I need to use the GPU for matrix-vector operations and the code that I'm working was already implemented using PETSc, obviously I choose the PETSc ViennaCL-GPU solution. The original code works perfectly, but when I use the GPU parameters, a SEGV occurs in some test cases.<div>Valgrind says that is a problem with PetscMallocAlign at memalign but, some times, it says that the problem is MatGetDiagonal.<div>I'm sending the configure.log because I don't know what are the cause of the problem (hope the problem is the configuration), and I would like to know if some similar problem were reported by PETSc-ViennaCL users and PETSc-CUDA users too.</div><div><br></div><div>PS: My computer has a top AMD GPU and I'm not sure that I can find a NVIDIA GPU computer to test my code, so OpenCL solutions are better to me then CUDA.</div></div> </div></body>
