unknown iteration time?

ixfd64 · 2010-01-08, 05:21

Prime95 (running on my MacBook Pro) just displayed the following line:

Quote:

Per iteration time: Unknown

That doesn't seem too normal. Is this something I should be concerned about?

Happens when your clock is set back to a time before the last status output. Still better than a negative time, and not exactly a reason to disable NTP either.

From Prime95's source, commonb.c, the part where it can decide to put "Unknown" there:

Code:

/* The timer could be less than zero if the computer went into hibernation. */
/* Hibernation is where the memory image is saved to disk and the computer */
/* shut off.  Upon power up the memory image is restored but the RDTSC */
/* timestamp counter has been reset to zero. */

Ah, that clears it up. Thanks for the help.
