Wondering what happened to cause the sudden Sec/TS reduction at Phase change:

help. I've got two host ids now and s/Ts have gone down dramatically (after enforced exit by power cut). Does it matter? The model looks ok (nothing odd showing up in cpview) and is due to finish in about 30hrs. Any advice on merging computers / delete this host or shall i just leave it alone?

Marj

&gt; Has it gone 'fast processing iceball' Jim..?
&gt;

Sorry for the delayed response, Nick; I went out of town -- not least of which reasons was to collect a new machine, a P4 3.4 GHz Pentium on the new 775-pin array. (Intel still calls it a P4, probably because it is on the Prescott core, but ASUS calls the MB P5P800. [My other four, with Northwood cores, are on P4P800 boards.] It's fast; at first Trickles, the two Models show 2.48 &amp; 2.50 S/TS, respectively, yielding a rather impressive [in my prejudiced opinion] 1.25 s/TS throughput.) Quieter than the other machines. too -- thanks, probably, to a 120mm case fan.

By the way, I tried to gin-up Yoper Linux on the new box. No joy -- so Ebox runs SuSE Linux 9.1.

To your question. Finally. No fast-processing ice-ball and no other obvious symptoms, at least none I've seen. The machine continues processing its two Models at a similar rate as before -- except with the anomalous S/TS time for one.

Edit: That Run has now "averaged up" to 2.37 s/TS.
Unlike Marj's situation, the Machine ID didn't change.

Happy Holidays,
Jim
