摘要： A system and method for performing a data backup with a stochastic scheduler in a distributed computing environment are described. A data set on a client is tracked. The data set is to be maintained with a backup data set on a centralized server within the distributed computing environment. A time period during which to initiate a data backup session for the tracked data set is selected. An instance of a backup session application on the client is periodically executed. The client attempts to initiate a connection with the centralized server beginning at a random start time during the selected time period. The client regularly reattempts the connection initiation following each failed connection initiation attempt. The tracked data set is selectively copied into the backup data set upon a successful connection initiation. Upon each successful data backup session for the tracked data set, a new random start time within the selected time slice for a next data backup session is generated.

摘要： Log entries in a system that produces status or other log data (ASIC verification system, for example) are saved in a circular buffer until a trigger event occurs. Typically, the system operates on a Device Under Test (DUT), but may apply to other systems that simply monitor or gather information. When the trigger occurs, a window of the saved log entries are saved to disk. A level of granularity of the reporting for the log entries is set at any point between low level (cycle based) reporting (recording every event) to high level functional descriptions of the processes or activities performed by the system, DUT, or other item being monitored. Log data from various modules of the system are grouped together to provide a logical view of the recorded log entries.
