Hi, > It looks like ViennaCL in petsc doesn't support single precision
(which I need cause my (old) GPU doesn't support double precision). I get the following error:Cannot use viennacl withOUT double precision numbers, it is not coded for this capability Is there any way this can be enabled in the build? This may be an oversight. Can you try adding self.double = 0 to the constructor in config/PETSc/packages/viennacl.py?
Thanks, Matt. Do we want to provide some automatic marshalling to single precision if not provided by the device? For 'production use' it doesn't really matter, because GPUs today which offer only single precision are generally rather low-end and won't provide any substantial benefit over CPUs. However, it can be handy for debugging purposes. Any opinions?
Best regards, Karli
