[jira] [Created] (MADLIB-1398) Fit Multiple Model does not utilize GPUs

Orhan Kislal created MADLIB-1398:
------------------------------------

             Summary: Fit Multiple Model does not utilize GPUs
                 Key: MADLIB-1398
                 URL: https://issues.apache.org/jira/browse/MADLIB-1398
             Project: Apache MADlib
          Issue Type: Bug
          Components: Deep Learning
            Reporter: Orhan Kislal
             Fix For: v1.17


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.
