Re: MAGMA GEMM Sources for Fermi Released

Hello Mark, I completely understand that Cublas Gemm is much optimized than MagmaBlas gemm. I am working on a problem which requires me to use GPGPU simulator. I have a CUBLAS Gemm in my application, as the Cublas GEMM is not opensource, GPGPU simulator cannot extract the PTX from it. The next best ...

Re: MAGMA GEMM Sources for Fermi Released

Hello Mark, Thanks for your help. As, I just need the MagmaBlas dgemm function I just wrote a sample code. In my sample test code, I malloced some host arrays and some device arrays. Initialized it and called dgemm function. The code compile properly after giving the -lmagma and -lcusparse flags. I ...

Hello Mark, I really thank you for the reply. I am using an Intel-I5 machine with Ubuntu 14 on it. I am using gcc 4.6.4 and g++ 5.4.1. I am compiling it with make and I am posting my make.inc file for your reference. I have commented out or deleted any options related to fortran compilation as I int...

Re: MAGMA GEMM Sources for Fermi Released

Hello, Thanks for the reply, for my work I need to only use the open source Magma Blas_Gemm . Also, it calls cublasgemm if the dimensions are not multiple of 96. It does not specify any particular warning about large sizes (large sizes with dimensions multiples of 96 must work). Also, would the magm...

Re: MAGMA GEMM Sources for Fermi Released

Hello,
Why does Magmablas only works when m,n,k are multiple of 96?
Can it work if m,n,k are not multiple of 96?

Thanks and Regards

Re: Using Open Source MagmaBlas_sgemm Api without Cublas lib

Thanks a lot Mark.
Can you please help me with a couple of questions.
1)I want to just use Cuda, I dont want to use any MKL,ATLAS,ACML library, so I am supposed to set only the Cuda path in bashrc and make.inc file,right?
2)Do you have a code example on using magmablas_gemm?

Thanks a lot, Mark
