Pentium4 HT

[col_sanders]

I've been searching around this topic and have been finding information regarding ht but nothing too definitive. I'm wondering if I should either
1. Run 2 standard clients on HT enabled P4
2. Run 1 -smp 2 client on HT enabled P4
3. Run 1 standard client on HT enabled P4
4. Run 1 standard client on HT DISABLED P4
:)
PPD may not be so great for this little box but its only a 120 watt dell that I have sitting around that I use for running a mumble server so I'd like to get some use out of those extra clock cycles.
Its a Pentium 4 530 3.0 GHz

As I recall:

1 standard client with HT is considered the "right" thing to do. :)

2 standard clients with HT gives 1/3 more points but delays the scientific result so its considered the "wrong" thing to do. :bang head

-smp is too slow on a P4. :(

A P4e will make about 45 ppd/GHz on non bonus WUs and perhaps twice that on the bonus uniprocessor WUs. Running 2 instances with HT makes up to a 30% increase in ppd, but closer to 25% on most WUs and almost nothing on some (one WU floods the FP registers). You have to decide if the very power hungry P4e is worth running at all.

I'll just be running one instance of the standard client. That way I still have the other thread open on the cpu to do work. I have the machine running 24/7 anyway since it serves as a mumble voice server and one game server for my gaming group online (dell optiplex gx280)
thanks for the replies :)

Run 6.29 in -configonly and remove its service there.
Search the registry for the 5.04 service. It's somewhere in HKEY_LOCAL_MACHINE/SOFTWARE/ and delete the FAH key (that's not it's real name). Then delete the files from the folding directory(s) and you can start fresh.
