Central computer evaluation, February 14-28, 1955

Abstract

From 13 February to 28 February 1955, the performance of the central computer was monitored by studying log entries and by carrying out a series of tests on 28 February. Mean good-time and the per cent of assigned time that was unusable was determined by examining the log. Margins and trends in the margins were also determined. The test on 28 February consisted of shock tests and an eight-hour period during which various reliability programs were run.
