Abstract

In this paper, we present a scheme of Prestack Kirchhoff Time Migration(PKTM) with multi-GPU. Firstly, we intorduced three main optimization points of GPU code of PKTM, then we test the code with a real field data. After analysis the efficiency curve, we proposed a multi-GPU flowchart of PKTM. it first splits the seismic data to different GPU nodes according to the offset range and collecting and sorting the result to CRP gather , the proposed method can reach the maximum efficency of GPU PKTM code.
