We present results of performance measurement of our astrophysical fluid dynamics code with Adaptive Mesh Refinement (AMR) scheme. As an example of its application for astrophysical phenomena, we show the results of 3D simulation of Rayleigh-Taylor instability in expanding supernova envelope and the possibility of reconciliation of the present model with observations. The efficiency of memory and CPU-time savings is discussed and measured with this simulation. Its result shows that our code has the ability to simulate phenomena with wide dynamic ranges even in limited computing resources.
