Copying data to the CPU (peripheral -> host) is expensive too, and it's perfectly possible to just replace peripheral -> host with peripheral -> device. I don't know if that is what blazingsql does, but it shouldn't be discounted.
- felipe_aramburu 8y agoIf you mean something like network card ==> device via RDMA we are not doing that yet but are currently working on this implementation. These past few months we have focused more on adding functionality to libgdf. We are now optimizing some of the i/os like this one you mention here. As of now if it goes over the wire it is being copied into pre allocated pinned memory buffers then sent to GPU. This will go away in about a month or so.
