>>But, you mean in that case, fortran does not allocate new memory for 'b', just passing the reference of the 'a' array descriptor. Allocation or not, use of array descriptor (new or reused) or use of reference to first cell all depend on how you program and the implied (re...
In the above example, you obtain 12 bytes of memory from the function MALLOC() and assign the address of that block of memory to the pointer P. Example 5: Dynamic allocation of arrays: PROGRAM UsePointers REAL X POINTER (P, X) ... READ (*,*) Nsize ! Get the size. P = MALLOC(...
After you have successfully debugged your program, you can evaluate its performance with the Sampling Analyzer, a program designed to help you tune application performance, including memory allocation. The Sampling Analyzer measures and graphically displays your application's performance profile and suggest...

memory, managed memory is not pinned and static, but migrates between the host and device on access. The system (driver and OS) controls the physical page movement. Specifically, in CUDA C/C++, managed memory usage consists of replacing calls to cudaMalloc() with cudaMallocManaged(), and ...
