Codemon: Tool for Performance Test and Analysis Based on pfmon

A method for using the Itanium 2 performance counters for bottleneck analysis is very complex and inconvenient. To cover this shortage, new model based on pfmon is proposed to monitor the performance issues in programs by using the "bubble" counters for stall analysis. The Codemon derived from the model is designed and implemented. In additions, the tool is used to characterize an application named "BNLAG2D", the results can tell user what about this program is and how to improve the performance. Performances achieved is 15 percent higher than the original program.
