sorry, i do not see "obvious" way to write a kernel :(

thanks a lot! Couple of questions: for the first part, gemm side, tmp = S2*K; % gemm aren't we doing here a bunch of un-necessary processing? for the batch dot product - forgive my ignorance please, but i do not see how to plug in batch processing instead of the loop for i = 1:a*r Q2(i) = tmp(i,:) *...

I have 3 dimensional matrix S with dimensions [A, R, M] , and i have 2 dimensional kernel K with dimensions [M, M] . I need to generate the output array Q with dimensions [A, R] , and Qij element of this array is calculated as Sij: * K * Sij: ** H (Hermitian conjugated) I can do this brute force by ...

thanks, will try to use.
Just for clarification - j - is "imaginary" 1.

Hello,
let say I have a vector .
I want to convert it to the vector .
Is there anything in MAGMA to address this operation?
Thanks much in advance,

hello I have python code that i am trying to convert into c++ (and accelerate using MAGMA). So, in python domain the operation in question looks like : R2 = Rx.dot(np.matrix.getH(Rx)); so i was trying with MAGMA various permutations of // allocate matrices and on the device err = magma_cmalloc(&d_a,...

Hello, in the description of the matrix-matrix operations, the value for trans is provided as one of the following: = MagmaNoTrans[: op( A ) = A. = MagmaTrans: op( A ) = A**T. = MagmaConjTrans: op( A ) = A**H. When I specify any option but MagmaNoTrans , then the d_c is not updated, when using magma...

Hello, Documentation provides following description for macro: magma_setmatrix ( m, n, elemSize, hA_src, lda, dB_dst, lddb, queue ) When i try to use it (well, c-version of it), i am getting following error: macro "magma_csetmatrix_v1" passed 7 arguments, but takes just 6 magma_csetmatrix( m, k, Rx,...

Mark, thanks for your feedback. I am having difficulties in calling cublas functions while using MAGMA, as I am using complex arrays, and there is no straightforward conversion between MAGMA complex types magmaFloatComplex (or magmaDoubleComplex) and cuComplex (or cuDoubleComplex) in CUDA. Or did I ...

Hello, I am new to MAGMA, have a couple of questions regarding availability of functions: 1. in CUDA there is a cublas<t>dgmm() function allowing to perform element-wise matrix-matrix multiplication 2. Likewise, there is a function cublasGetMatrix allowing to extract subarray from array. Question - ...
