It is called VAX Software Performance Monitor, or VAX SPM for short. It allows program tuning based on either clock-driven sampling, or trace-driven sampling. In addition, the package can help with system tuning and accounting. I have used the programing tuning portion, and was satisfied, but felt that it would not be useful until the final stages of programming. The system tuning portion of the package provides interesting data on how your system runs. The big deficency here is that is does not appear to acknowledge the fact that we have eagles, so we can not get a realistic IO estimate from it. This seems to be because the eagles are on a massbus adaptor. Dean Stephan { engvax!dean@CIT-VAX.ARPA } Hughes Aircraft Company
