Also ... a little more information, this happens with relatively small matrix/ vector pairs...
300 x 100 matrix and 100 element vec. I'm running with a consumer grade GPU, but it has dealt with matrices much larger than that.

If I dont make the backend::memory_read call, that test will pass, but my next unit test; A Matrix * Matrix test will fail. Does the Vector product or memory_read seem wrong to you? Thanks, Andy
