| Abstract(in English) | On-the-fly computation in the field-programmable gate array (FPGA) used for the switching hub is one potential way to accelerate the computation of data exchanged through the hub. However, for large scale scientific computation, it is difficult to implement such an accelerator on the FPGA used in high performance computers. Here, a hardware local essential tree (LET) generator used in an N-body simulation is implemented on the FPGA of PEACH2 (PCI Express Adaptive Communication Hub ver2), a low latency switching hub for high performance GPU clusters. By using the pipelined on-the-fly execution with a multipole acceptance criterion judging module and a data updating module, the generation performance is 2.2 times faster than that with the CPU. When data communication is considered, a performance 7.2 times faster than when using the CPU can be achieved. |
