Characterizing Compiler Performance for the AMD . . .

Application performance on a high performance, parallel platform depends on a variety of factors, the most important being the performance of the high speed interconnect and the compute node processor. The performance of the compute processor depends on how well the compiler optimizes for a given processor architecture, and how well it optimizes the applications source code. An analysis of uni-processor and parallel performance using different AMD Opteron compilers on key SNL application codes is presented.
