摘　　要：通过系统配置,实现在"天河一号"编译和运行GAMIT。通过单任务和多任务运行测试了"天河一号"平台上GAMIT的计算效率,并与其他平台对比。结果发现"天河一号"的GAMIT计算效率相对较低。天河一号的优势是并行计算,而GAMIT计算过程属于串行计算,且有较大的数据传输需求,这是导致"天河一号"GAMIT计算效率低下的根本原因。Through the system configuration ,we achieve the purpose of compiling and running GAMIT on“Tianhe-1a” super computer .By the single task and multi-task test ,GAMIT computational efficiency of“Tianhe-1a” platform is obtained ,and compared with other platform .It is found that GAMIT computing efficiency of “Tianhe-1a” is relatively low .The advantage of “Tianhe-1a” platform is parallel computing , while GAMIT computing process is a serial computing and requires a great quantity of data transmission . That's the primary cause of “Tianhe-1a” low GAMIT computing efficiency .
