There is a new product "SpeedShop" works under IRIX 6.2. It is an integrated package of performance tools. It is a powerful tool set. It can attach to debugger and supports running Purify. We can use it to get profiling information. There is a man page on SpeedShop.
For Profiling, you can try the following:
# myexe is the program to be purified; if your program needs arguments, you can put arguments after myexe.
# myexe.fpcsampx.NNNNN is the file created by the previous commend ssrun. Where NNNNN is the process ID of the executed process. Each time ssrun is used, a new file with a different NNNNN is generated. Now you get the CPU information for your program.
If your machine has IRIX 5.3:
The profiling results are listed in your mytest.prof file. <\ul>
