[SOLVED] errors when using magma_dgels_gpu

Postby ReL » Wed Jun 20, 2012 10:42 am

Hello,

I have noticed some errors when using magma_dgels_gpu:
Code: Select all
CUBLAS error: memory mapping error (11) in magma_dsetmatrix at dset_get.cpp:98
testMagmaDGELS: dset_get.cpp:160: void magma_dcopymatrix(int, int, const double *, int, double *, int): Assertion `status == cudaSuccess' failed.


magma_dgels3_gpu works fine.

I have attached a sample code sample that enables reproducing the issue:
testMagmaDGELS.cpp

Hi Remi,
I could not reproduce the problem using MAGMA 1.2.1. It could have been a bug in some wrappers that we have fixed in 1.2.1. Please update to see if you still have the error. Using your example code I get
Code: Select all
[tomov@cumin testing]$  ./testMagmaDGELS
Optimal work space 8514
LLSP solved successfully
Solution vector:
   0.953333
   -0.843333
   0.906667

Hello Stan,

Indeed the problem is fixed in MAGMA 1.2.1. Thanks for looking into that.
