Abstract

Data throughput in modern telescopes instrumentation have been steadily increasing over the last decade. The few gigabits per second range is now the lower bound, and bandwidths as high as tens of terabits per second are expected with the Square Kilometer Array. We present a new approach based on DPDK, and its support for GPUDirect recently introduced by Nvidia to perform DMA from Network Interface Controller (NIC) to GPU memory, to answer very high throughput data acquisition in astronomy.
