Thanks

Wrong Output

Hi, I wrote one interface to use magma cholesky decomposition, but I am getting all zeros in the output. Below written is the interface code which takes as an input the dimension m, the matrix a and info I tried it on a matrix of size 4392 x 4392. extern "C" void magma_chol(int m, double* a, int *in...

It worked, I forgot to remove the commented call.

Re: Using MAGMA without Intel MKL

Hi, I used the code of magma_dpotrf available in one of the other posts on this forum and made a file out of it: /* -- MAGMA (version 0.1) -- Univ. of Tennessee, Knoxville Univ. of California, Berkeley Univ. of Colorado, Denver June 2009 */ #include "cuda_runtime_api.h" #include "cublas.h" #include ...

Re: Using MAGMA without Intel MKL

I used
extern "C" int magma_dpotrf(char *, int *, double *, int *, double *, int *); in magma.h and called the function
but it gave error: magma_dpotrf.cpp:(.text+0xa1): undefined reference to `magma_get_dpotrf_nb'
while linking it. I tried changing the declaration in auxilliary.h but of no use.

Re: Using MAGMA without Intel MKL

Hi,

I am currently using the Cholesky decomposition module of MAGMA. So I need to link this module with rest of the "C" Project. But with the existing modules, I couldn't link it successfully. Could you provide with the code for magma_dpotrf and magma_get_dpotrf_nb .


Thanks

Re: Using MAGMA without Intel MKL

The flags, -lmkl_sequential -lmkl_intel -lmkl_core -lguide worked for me with MKL 10.2 . Another problem I am getting is linking MAGMA to a C (not CPP) Project. It is not able to find definition of the magma functions. As far as I think, the magma codes are written in cpp and all the test files are ...

Re: Using MAGMA without Intel MKL

Actually I installed Intel MKL 10.2, but I am getting the error:

/usr/bin/ld: cannot find -lmkl_em64t
collect2: ld returned 1 exit status

I checked the library directory but could not find any library of libmkl_em64t.a , Is there any new name for that ?
