Arioc: High-concurrency short-read alignment on multiple GPUs
Fig 2
Speed versus sensitivity for three GPU memory-layout techniques.
Speed (reads/second) is greater when GPU peer-to-peer memory interconnect is used, for a range of sensitivity (% concordant) settings. Speeds are highest when the H and J tables are partitioned across device RAM on all available GPUs and GPU peer-to-peer memory accesses use the direct P2P memory interconnect. Speeds are lower with H in device RAM on each GPU and J in page-locked system memory. Speeds are lowest when H and J both reside in page-locked system RAM. H table: 25GB; J table: 52GB.
