It is necessary to know where to use this function and where not to use. There is no hard and fast rule but my recommendation is, use this function only for intermediate operation. For example, if your application want’s some reduction on your input data (let say Sum reduction), then you need to reduce first all blocks data and store this intermediate result in intermediate array then again ...

cudaMalloc is a function that can be called from the host or the device to allocate memory on the device, much like malloc for the host. The memory allocated with cudaMalloc must be freed with cudaFree.Other variants of cudaMalloc are cudaMallocPitch, cudaMallocArray, cudaMalloc3D, cudaMalloc3DArray, cudaMallocHost and cuMemAlloc.

1 dag siden · Hi, I am developing a C application that uses cublas to accelerate some matrix multiplications. Unfortunately I am running into some strange behavior when I link my application to .cu code. Problem: Application (using cublas) runs without problems when not linking to the cu code. When linking cu code, application fails at cudaMalloc and/or cublasCreate. My C …
