Thanks! Take a look at branch dalcinl/cuda-handle https://bitbucket.org/petsc/petsc4py/src/cec7da13bbb407a1b376f8e6b46b1ef31ca6e9b3/?at=dalcinl%2Fcuda-handle PS: Ashwin, you could use contextmanager https://docs.python.org/2/library/contextlib.html#contextlib.contextmanager to handle the get/restore using Python's with statement, eg. with gpuarray(vec) as array: launch_cuda_kernel(array) -- Lisandro Dalcin ============ Research Scientist Computer, Electrical and Mathematical Sciences & Engineering (CEMSE) Numerical Porous Media Center (NumPor) King Abdullah University of Science and Technology (KAUST) http://numpor.kaust.edu.sa/ 4700 King Abdullah University of Science and Technology al-Khawarizmi Bldg (Bldg 1), Office # 4332 Thuwal 23955-6900, Kingdom of Saudi Arabia http://www.kaust.edu.sa Office Phone: +966 12 808-0459
