### dgemv returns wrong results

Posted:

**Wed Dec 14, 2011 10:01 am**hi

i am using magmablas_dgemv function for calculating a matrix vector product however the results do not seem to match those generated by the magma_dpotrf_gpu (followed by) magma_dpotrs_gpu.

the matrix is really small 8x8. the hardware i am running it on is a C2050.

does anyone face a similar problem? if yes could you suggest what must be done to solve this issue?

kindly help

thanks in advance
