select_ipc_gpu dataframe does not get cleared from GPU memory #365

We are using pymapd to get data in gpu dataframe using select_ipc_gpu. We observed that over time, the memory usage of omnisci in GPU keeps increasing until entire memory gets filled. Is there a way to clear it periodically?

Hi Anirudh,

Thank you for the report. This does appear to be a problem in the OmniSci DB, not the python client, but I don't have a timeframe to fix it yet. I believe you have an issue open on the DB, so I'll close this issue.

I did create a related issue for the pyomnisci library (which is the replacement for pymapd) in https://github.com/omnisci/pyomnisci/issues/17

Thanks, Mike
