Shared Memory Example Declare shared memory in CUDA C/C++ device code using the __shared__ variable declaration specifier. There are multiple ways to declare shared memory inside a kernel, depending on whether the amount of memory is known at compile time or at run time. The following complete...
Declare shared memory in CUDA Fortran using thesharedvariable qualifier in the device code. There are multiple ways to declare shared memory inside a kernel, depending on whether the amount of memory is known at compile time or at runtime. The following complete code example shows various methods...

Since x and y positions are mainly used in combination, it is obvious to combine the two elements into a single value of type float2. This allows the CUDA run-time to load both values at once instead of retrieving it from two different memory locations. Less obvious but similar is the ...
2. Possibility to choose CUDA / CPU (for some reason torch doesn't want to allocate shared memory so I can only use the LARGE model on the CPU ) 3. Perhaps configuring the software in such a way that it allows shared memory allocation at the expense of speed. ...
performance of stencil operations using an advanced feature of the GPU: shared memory. You do this by writing your own CUDA® code in a MEX file and calling the MEX file from MATLAB. You can find an introduction to the use of the GPU in MEX files inRun MEX Functions Containing CUDA ...
CUDA 11.5 improves code generation for loads and stores when__builtin_assumeis applied to the results of address space predicate functions such as__isShared(pointer). For other supported functions, seeAddress Space Predicate Functions. Without an address space specifier, the compiler generates generic...

You have an instance of concurrent access. To prevent that, use acudaDeviceSynchronize()call after each kernel call, before using unified memory on the host. Furthermore, in a multithreaded environment, this is complicated by the fact that each kernel call places all UM allocations in an “un...
With CUDA, programming reductions and managing shared memory can be a fairly difficult task. In the example below, the compiler has automatically generated optimal code using these features. By the way, the compiler is always looking for opportunities to optimize your code. ...
