We have developed Remote-GRAPE, a subroutine library to use the specialpurpose computer GRAPE-3A. The GRAPE-3A can efficiently calculate gravitationalforce between particles, and construct neighbor lists. All other calculationsare performed on the host workstation (WS) which is directly connected toGRAPE. The use of GRAPE for Smoothed Particle Hydrodynamics (GRAPE-SPH) can inprinciple greatly speed up the calculations on WS. However the currentbottleneck of GRAPE-SPH is that its performance is limited by the speed of thehost WS. To solve this problem, we implement Remote-GRAPE; it allows us to runapplications which use GRAPE-3A hardware on the significantly faster computersthan the physical host WS. Thus, we can take advantage of the fast computerseven though they can not physically be connected to GRAPE. The Remote-GRAPEsystem is implemented on the Parallel Virtual Machine (PVM). In this paper, thedetail of implementation and performance analysis are described.Comment: 24 pages LaTeX file with 10 PostScript figures, to appear in Ap
