I’m trying to understand Omnisci’s architecture of using GPU. First, when does it load the data to GPU? Is it loading all the data to GPU when it ingest data, for example, using COPY FROM command? Or, is it load the data to GPU when I execute the first query?
Second, What will happen if the GPU memory is full? Does it use both GPU and CPU memory? I’m using K80 GPU which has 24GB GPU memory. Approximately how much GB data I can ingest without utilizing the CPU memory?
