Implicitly Included Flags

This section contains descriptions of flags that were included implicitly by other flags, but which do not have a permanent home at SPEC.


System and Other Tuning Information

Platform settings

One or more of the following settings may have been applied to the testbed. If so, the "Platform Notes" section of the report will say so; and you can read below to find out more about what these settings mean.

autoup=<n> (Unix)
When the file system flush daemon fsflush runs, it writes to disk all modified file buffers that are more than n seconds old.

PARALLEL=<n> (Unix)
If programs have been compiled with -xautopar, this environment variable can be set to the number of processors that programs should use.

STACKSIZE=<n> (Unix)
Set the size of the stack (temporary storage area) for each slave thread of a multithreaded program.

submit=echo 'pbind -b...' > dobmk; sh dobmk (SPEC tools, Unix)
When running multiple copies of benchmarks, the SPEC config file feature submit is sometimes used to cause individual jobs to be bound to specific processors. If so, the specific command may be found in the config file; here is a brief guide to understanding that command:

tune_t_fsflushr=<n> (Unix)
Controls the number of seconds between runs of the file system flush daemon, fsflush.

ulimit -s <n> (Unix)
Sets the stack size to n kbytes, or "unlimited" to allow the stack size to grow without limit.


Flag description origin markings:

[user] Indicates that the flag description came from the user flags file.
[suite] Indicates that the flag description came from the suite-wide flags file.
