IBM LoadLeveler for AIX 5L: Using and Administering
With 64-bit support for applications running under LoadLeveler:
- Users and Administrators can assign 64-bit integer values to selected
keywords in the Job Command, Configuration, and Administration files.
System resource limits, with the exception of CPU limits, are treated by
LoadLeveler daemons and commands as 64-bit limits.
- The LoadLeveler commands and the GUI (xloadl) accept and display
64-bit information where appropriate.
- Both sets of 32-bit and 64-bit LoadLeveler APIs and libraries are
available for application development. LoadLeveler and MPI
checkpointing libraries support both 64-bit and 32-bit applications.
- Accounting statistics of completed jobs that have 64-bit integer
values are preserved in the LoadLeveler history files as 64-bit data.
The LoadLeveler interfaces that access the history files correctly process
these 64-bit statistics.
