Are there any tools to help me with OpenMP programming?
The standard debugging and profiling tool on the Sunfire machines at HPCVL is Sun Studio, which provides a GUI and is well documented internally. It is able to handle multi-threaded code, i.e. programs that were written using OpenMP. If the home directory of the compiler suite (/opt/ss10/SUNWspro/bin) is in your PATH, the tool may be invoked by simply typing sunstudio at the command prompt. Help is easily invoked, for example by clicking on “Help”, selecting “Contents” and then going to “Managing Threads” in the menu that appears. Sun Studio supplies both a means to debug your program, and to perform timing experiments on them (profiling). The tool might be used to track down bottle necks to the level of single lines of code, or even assembly language instructions. Quite often, the best way to check the performance of a multi-threaded program is timing it by insertion of suitable routines. This can be done by calling the subroutines ETIME and DTIME, which can give you information about
