top would not help. It simply says that my process is sometimes only taking 30% CPU time, but it gives no indication *why*. Note that it is only a guess that I/O are to blame. Moreover, a system tool would not tell me in what part of my programs the problem is located. "prun" might give some hint. However, since my programs use external programs as well as compiled components and interfaces, I was hoping for a tool that tracks all I/O processes occuring during my computation. Perhaps there is a system tool for that purpose. I think it would help me if some tool would produce a list of all file names to which I/O happened, and record the I/O time for each file.
