WebFeb 1, 2024 · The __align__ (n) qualifier can be used before structs and classes to force alignment of all members to n bits. For CUDA's purposes, n should be some multiple of 4 e.g 4, 8, 12, 16, ... with 16-byte alignment being preferred if your problem size is not too big. For example: struct __align__(16) { float x; float y; float z; }; WebJan 8, 2008 · Both array[0] and array[1] must be properly aligned, and the sizeof the array is twice the size of one of its elements, that is, twice the sizeof(r). So sizeof(r) must include whatever padding might be needed to make the alignment work properly. It's not a matter of rounding up the result of sizeof; it's that

WebFor a natural alignment scheme, the compiler would only have to add a single byte of padding at the end of the structure. This padding is added in order to satisfy alignment constraints for arrays of these structures. Another point worth mentioning is the use of __attribute__ ( (packed)) on a structure type. WebDec 11, 2008 · The very first element of your structure is a float4, and that clearly must be aligned to 16 bytes (so that it can be fetched in one opcode). So your whole structure must be aligned to 16 bytes. The question is why nvcc doesn’t realize this itself. align (16) does fix the situation.
