Description

It seems the fit multiple model function is not utilizing the GPU properly. 

 

I see that sessions are created and the memory is allocated but the GPU utilization is almost always at 0%. The running times are very long compared to the regular fit function as well. In the same setup, a single fit iteration takes ~300sec. Multifit with 3 models takes ~7000 sec.
