I wrote a program with cudalbfgs and tested it with 550Ti and GTX 760. The result with former card looks like normal, but result with GTX 760 is incorrect(most of the values are zero). So I am wondering do I have to be aware of something when using different card with different compute compatibility?

The issue was due to uninitialized memory provided as the initial guess to the optimizer.
