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

     [ https://issues.apache.org/jira/browse/MADLIB-1398?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Orhan Kislal closed MADLIB-1398.
--------------------------------
    Resolution: Not A Bug

Closer inspection showed that this is not an issue. GPUs are being used, just that the execution time of non-GPU parts are significantly longer.

> 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.
