Abstract(in English) | Computational Fluid Dynamics (CFD) is known as an application that requires massively floating point operations, and the cost for using powerful supercomputers long time often becomes great. Instead, we propose a cost effective accelerator that enhance the computational speed by using hardware modules built in multiple FPGAs. Here, we adopted UPACS, a CFD package developed by JAXA, and based on its profiling, we selected two kernels as targets of acceleration: the time integral routing that occupies the largest computation time and the error modification routine whose data dependency is relatively low. Hardware design of the above kernels was described in Verilog-HDL and Xilinx ISE 8.2i is used for logic synthesis. As a result, we achieved about 170 times performance of the Itanium2 1.5GHz PC on the error modification routine by using two VX4VLX200 and two VX4VSX55 FPGAs. On time integral routine, the speed is 46.8 times of the Itanium2 1.5GHz PC by using two FPGAs. |
