Re: Software dependencies for MAGMA

MKL can be downloaded from http://software.intel.com/en-us/intel-mkl/
or any other BLAS LAPACK or GOTO or ACML should be fine.
The make.inc has an example of how to link them.
Sorry for the delay.

Re: MAGMA 0.2 does not seem to work with CUDA 3.0

Can you please tell us what kind of problem you are facing ?
did you recompiled all the BLAS routines? with sm_20 changes in the makefile ?

Re: magmablas gemm

Hello, I am doing benchmarking of gemm implementations of magmablas and CUBLAS. I have some queries about using various versions of GEMM of magmablas and cublas. 1. None of the GEMM variants have "_gpu" postfix, does this mean that we can call these functions with input matrices in CPU memory. I ha...

Re: magma_dsposv_gpu does not work when NRHS >1

Thank you for the information.
I am trying to isolate the problem. I will get back to you soon.

Can you tell me about the matrix size and LDA ( Leading dimensions )
Thanks

Re: sgetrf matlab mex file - crashing...

1. Do you get the same segmentation fault
using
cudaMallocHost( (void**)&h_work, (lwork+32*maxnb)*sizeof(float) );
instead of
h_work = (float *) mxCalloc((lwork+32*maxnb),sizeof(float));

2. What about using problem size 128 X 128?

Re: sgetrf matlab mex file - crashing...

Can you tell what did you use for the input matrix dimension? N X N
I mean , what is the value for N ?

Re: eigenvalue solver for real symmtric matrix

Hopefully in next release we will have a suite of eigenvalue solvers.
We are planning to have full functionality with multi GPU.
We have done some experiments with hybrid (multi-GPU) Cholesky factorization and xGEMM.
and the results are good so far.
