As applications growing more complicated,the demands of large scale system simulation for computing resource are becoming higher and higher.Four characteristics of large-scale system-of-systems simulation,such as Multi-Sample,Ultra-Real-time,Complex model calculation,Cause and effect coordination were summarized.The demands in computer platforms for computing capability,communication,I/O,parallel execution,modeling and development were analyzed.The shortcomings of large-scale system-of-systems simulation using HLA architecture on workstation or COTS cluster system were pointed out.System architecture and key technologies breakthrough of the high-performance simulation computer were introduced.Applications show that comparing with the solution using HLA and general high-performance computer,the high-performance simulation computer system has a better overall performance and higher productivity,for a general large-scale system-of-systems simulation,the runtime efficiency can be multiplied several tenfold to several hundredfold.
