MAGMA Forum

I'm trying to use MAGMA without MKL, which I saw a post for previously. I changed the make file to point to the directory of my LAPACK and BLAS so's, and changed the LIB variable to not have -lmkl_em64t OR -lguide (put in -llpack).
When running testing_sgetrf_gpu I get the following error:

[rmchurch@cmodws66 testing]$ ./testing_sgetrf_gpu
device 0: Quadro FX 1700, 918.0 MHz clock, 511.3 MB memory

Usage:
testing_sgetrf_gpu -N 1024

!!!! device memory allocation error (d_A)


N CPU GFlop/s GPU GFlop/s ||PA-LU|| / (||A||*N)
==========================================================
Segmentation fault

Is this because of a bad build? I have probably missed something to change/add in the make file, though I have no idea what. Any ideas?

Hello,
The testing drivers assume memory on the card of size ~1GB and try to allocate memory for matrix of size 10,000 x 10,000. I see you have 511MB. We will change this in the future - to read the card specification and run tests that are according to the card,s memory size. For now you can try smaller problems by giving the size directly, e.g. Hope this was the problem.

Thanks, that was it, I should have just looked at the code.
