Transfer results from the device to the host. IY=IY+INCY Is there any example for Fortran about batch DGEMM? The most widely used is the DGEMM Purpose: DGEMM performs one of the matrix-matrix operations C := alpha*op ( A )*op ( B ) + beta*C, where op ( X ) is one of op ( X ) = X or op ( X ) = X**T, alpha and beta are scalars, and A, B and C are matrices, with op ( A ) an m by k matrix, op ( B ) a k by n matrix and C an m by n matrix. . #accessedsequentiallywithonepassthroughA. For example, the Hollerith Constants were not a thing in Fortran 90+, but gfortran compiles them just fine.
