If I recall right it was the "core duo mobile" model. Not the "core 2 duo". But I think that chipset was still based on the horrible Prescott platform with just the "lga" tag.

Even the mobile c2ds are core2 based... or maybe you were just referring to an older laptop. I believe they are clocked lower and may be based on the Allendale core, but its still faster than a P4.

The 21xx series Core2s can be picked up for dirt cheap these days and can overclock quite nicely; 3.2ghz is common and I've seen 3.5ghz on air several times. It will net around 2200-2500pts/day.

I have a dual PIII 700MHz (yeah I know, but it's just a file server and does just fine) that generates about 20pts a day.

Totally lame I know. Is that all they can do!?
Ya, I have a few running on P4 class PC's.

1 P4 3.2 ghz that averages about 67.31 PPD section every 1:14 hours
1 P4 3.0 Xeon that averages about 240 PPD section every 40 mins

^ OH! Sorry both of those are set to 50% CPU though

On the flip side, that same client installed on a core 2 duo dual core but only running on one of the procs (100% on one core so 50% total CPU)... so technically exactly the same clients gets me about 455 PPD Section every 21 mins.

Damn I might need to make a 2,000,000 point Badge at this rate.

What is the size limit again Dave?
I want to make this one "SPECIAL"

So I'm wondering what makes the new processors SO much faster and my guess is the much larger caches.

Paul its the multiple CPUs that outstrip yours... you don't have a dual or quad core machine do you?

Several things, mostly the number of transistors they throw into it. As they keep shrinking the die cast of the silicon they can squish more of them into the same real-estate. Things like Cache and designs such a SSE3 help.

The Pentium 4 is universally known as the dark days of Intel.
The Core Architecture is godlike.
Not only is it a return to P-M goodness, it dumped Netburst.

F@H is very L2 cache dependent, SSE3 optimizations aren't really used.
SSE3 is supposed to bring 100% or so improvements to divx encoding, but anyone worth their salt has moved on to h264.

I can't wait for nehalem.

FYI, for those of you running P4's w/hyperthreading... 50% usage is really 100% of your pricessing power, the only reason your task manager shows 50% is becuase it can still handle a 2nd thread, though at the cost of slowing down the 1st thread.

You can easily test this by running one instance of the standard (non SMP) client. You will see your task manager show 50% usage. Make note of how long it takes to complete a step. Then run a 2nd instance of the standard client and assign each one it's own "virtual" processor. Your task manager will show 100% usage but it will take you 2x longer to complete a step. On a dual core machine, running two instances in this manner will complete the steps in the same amount of time as if you were running a single client, but you turn in 2x the results.

Now if a real multi core machine shows 50%, then you really are only using half your processing power.

Default Weirdness

The 939 rig typically does a SMP step in 25-26 minutes. I noticed this morning that it didn't finish the WU as expected. The step times are now running at 1.18 hours.

Once it completes on its own, I'll shut it down and restart but what's up? Nothing else is running and in task manager only the fah cores are drawing CPU cycles. (The AMD Socket-A at 1.4GHz was about at this speed.)

I notice that sometimes with different work units... did you know what WU you had before vs now?

2653 (Run 36, Clone 180, Gen 1)

It started out doing each step at 26 minutes but somewhere about 60% it tripled in time. I couldn't bear to think of it stepping at an hour so I shut it down and re-booted the machine. Possibly there was some stray process interfering with F@H that wasn't showing in task manager. We'll see if the step time changes.

Question

New joys today...I'm not quite there, the urge to take this thing and bury it in the backyard has crossed my mind.

Whatever happened to the system killed the configuration of enough apps. (Possible drive issues?) Anyway in trying to get things back to normal I got this error message while trying to set-up F@H:

unable to connect to 'am2:8676'
sock error:generic socket failure, error stack:
MPIDU_Sock_post_connect<1228>:unable to connect to am2 on port8676, exhaustedall endpoints <errno -1>
MPIDU_Sock_post_connect<1275>: unable to connect to am2 on port 8676, No connection could be made because the target machine actively refused it. <errno 10061>
Press any key to continue

?????

I have this problem with a laptop. It is entirely heat related. If I close the screen (set to "do nothing" in power management), the unit heats up and slows down. If I leave it open, it chugs along and produces its 1127 pts/day.

Most performance mods need a watch and timed course to demonstrate actual improvement. Few deliver the advertised claims. Many are actually worse than stock. The best performance mods are made to the driver.

Emotional arguments - They're not just for chicks anymore.

Dave, sure dual and quad cores double an quadruple the processing power, but I think it was y2k who said even with just ONE of his cores running he was generating hundreds of points a day, and I'm not even close.

I mentioned larger cache because I believe the C2D's often have 2-4MB cache whereas a typical P4 was what, 512K?

I gotta upgrade to C2D's one of these days...

So many toys, not enough budget.
