		brechtUnsubmitted Done Inline Actions `mem_address_alignment()` seems like a more clear name, not sure what offsets have to do with it. I'm not sure what the require alignment is on CUDA, and on older CPUs SSE needs alignment as well. I suggest to use 16 as the default value here instead of 1. brecht: `mem_address_alignment()` seems like a more clear name, not sure what offsets have to do with…
