Concurrent user considerations

Invocations of the compiler are considered concurrent when their start time and end times overlap. This section provides the information about how the utilization reporting tool counts concurrent users and the ways to increase the accuracy of the usage reports.

When the utilization reporting tool counts concurrent users, it looks at the user account information that has been captured in the usage files. The account information consists of a user name, a user ID, and a host name. By default, each unique combination of this account information is considered and counted as a different user. However, invocations of the compiler by the following users must not be included in the count of concurrent users:
The utilization reporting tool can account for the above situations if you provide it with information regarding exempt users and users with multiple accounts. Here is how you can provide the information:
Notes:
  • When the number of concurrent users is adjusted with -qexemptconcurrentusers or -qsameuser, the utilization reporting tool generates a message to indicate that the concurrent usage information is adjusted.
  • The number of concurrent users might be zero if all concurrent invocations are invoked by exempt users. The tool also generates a message with this information.
