xfblasStatus_t xfblasMallocManaged(short** devPtr, int* paddedLda, int rows, int lda, int elemSize, unsigned int kernelIndex = 0, unsigned int deviceIndex = 0) xfblasStatus_t xfblasMallocManaged(float** devPtr, int* paddedLda, int rows, int lda, int elemSize, unsigned int kernelIndex = 0, unsigned int deviceIndex = 0)
This function allocates memory on the FPGA device, rewrites the leading dimension size after padding.
Parameters:
| devPtr | pointer to mapped memory |
| paddedLda | leading dimension of the matrix after padding |
| rows | number of rows in the matrix |
| lda | leading dimension of the matrix that indicates the total number of cols in the matrix |
| elemSize | number of bytes required to store each element in the matrix |
| kernelIndex | index of kernel that is being used, default is 0 |
| deviceIndex | index of device that is being used, default is 0 |
Return:
| xfblasStatus_t | 0 if the allocation completed successfully |
| xfblasStatus_t | 1 if the library was not initialized |
| xfblasStatus_t | 2 if parameters rows, cols, elemSize, lda <= 0 or cols > lda or data types are not matched |
| xfblasStatus_t | 3 if there is memory already allocated to the same matrix |
| xfblasStatus_t | 4 if the engine is not supported for now |
