    Long time no see Mapd!! I have some question.

    Q1. MapD provide tech of SSD-to-GPU memory (DMA)??

    Q2. I'm just asking because I'm just curious. Which parts of MapD-core do you think should be complemented by MapD developers? Where do you think you need more performance improvements?

    Thank you

    Hi @Jeon Woohyuck

    We really missed your interesting questions

    About your first question
    Omnisci db doesn't support DMA transfers from the disk to vram.
    The memory manager uses as first cache layer the system ram; this makes possible a fall back to CPU executions of the queries, and in the end you should need a 64gbit interface on disks to saturate a single pci-ex interface of a GPUs, so this approach would make sense on DB that use GPU as co-processors to offload some CPU work.

    Hummm...tough question.... Maybe Spatial joins
