Abstract : A week long test was run on the Parallel Function Processor (PFP) Monday June 12, 1989 through Sunday June 18, 1989. Temperature data was collected over a 103 hour period from Tuesday June 13, 1989 through Saturday June 17, 1989 at 32 points on the system. Plots of 31 of these points are included in this report, the 11th thermocouple did not work correctly, giving all negative temperatures. Four diagnostic tests, T3, FPPMU, T2, and FUNCTION were run in a continuous loop for the whole week. Results are given in two forms, per test and per processor.
