A method is provided for buffer allocation on a graphics processing unit. The method includes analyzing, by the graphics processing unit, a program to be executed on the graphics processing unit to determine, for an object in the program, a set of elements in the object that are designated to be accessed during an execution of the program. The method further includes allocating, by the graphics processing unit, a placement of the object in a device buffer on the graphics processing unit based on the set of elements to minimize a number of memory accesses during the execution of the program.
