Hi, it seems it is a regression that in the latest pyopencl version the retain argument to Event.from_int_ptr() is missing. It has been added to avoid a memory leak, see https://github.com/inducer/pyopencl/issues/113 best Gregor > > The tests use a lot of reduction, elementwise, and FFT (through gpyfft) > kernels with moderately large arrays (multiple stacks of 16x400x400 floats), > and I see no significant speed change (no tight-kernel-calling loops, sorry > !).
