Also, one litle trick I've discovered which can help a lot, especially on late model laptops, is to not completely close the lid and prop up the back to let more air underneath it when you aren't using the machine if you crunch full time on it.
Also try, with the lid opened ~ 3 to 4 inches, turning the laptop to rest hinge side up with the free edges resting on the table top. So it looks like an upside-down vee, or a tent. Cooling will be assisted by natural convection through the gaps between keys in the face of the keyboard, to where the hot stuff generally is beneath and then out the rear/underside vents.
It costs nothing, and is but the work of a moment to swap between this and the working position! :-)
Cheers, Mike.
LOL...
Yes, I've used the inverted vee 'cooling tower' technique too.
I just get a little squeamish when I think about the possible outcome if the 'tower' collapses or gets knocked over inadvertently . ;-)
I guess if you don't have kids and/or felines around it's OK, and it is more effective than just leaving the lid cracked open and the back propped up. :-D
Thanks all :) instead of the hinge side up, turning it sideways (so that laptop will rest on it's right side) will direct the fan's output (which is on this machine's left side) straight up. I will just have to make sure the cd's tray stays shut ;)
Anyway...
I was just given my first ABP wu to crunch. Apparently that app doesn't take the same approach to optimization as the einstein app does. At least I see only one binary. Any gains to be made in that department?

Nice one! Less reliance on the hinge for sure ... :-)
From what I've seen of disassembled dead lappies the hinge is often a sort of longitudinally offset cam with friction. So allegedly the screen/top stays where you put it, but the designers no doubt assumed the standard posture - heavy bum downwards. :-)

Thanks. I started wondering because the wingmen of a lot my workunits seem to report significantly less CPU-time per wu than my computer (ID: 1043520) does.

:-) But optimized apps aren't provided anywhere you would happen to know of?

No, but give the dev's some time. This project tends to be conservatively iterative, ie. get it right first then speed it up. I'm sure it will happen. :-)

So, here it is 5 months later. Any opti apps for Windows yet? I have an older laptop that can do SSE calcs. I like to contribute as much as possible to science, thus the need for speed. Someone mentioned a helper app that sizes up a CPUs capabilities, and gives the app that fills the bill to the WUs. If that's true, maybe there's nothing I can do to improve on the stock app I downloaded from E@H. Can somebody clear this up for me?

When a new version that is faster or better is tested out it does indeed become part of the "standard" application. If you want to be faster than stock you can, at the risk of more failures, engage in the beta trials of the newest and "best", but in general, you are doing the fastest possible processing.

The current S5R5 'hierarchical' search application actually consists of three different programs, called einstein_S5R5_3.05_windows_intelx86_n, where:
n=0: no processor optimisation, should run on any x86 processor
n=1: uses SSE code, so probably right for you
n=2: uses SSE2 code
There's a tiny loader program, which checks the CPU capabilities and invokes what it thinks is the right main program for your system. You can use Task Manager to check that it's made the right choice.
In addition, the S5R5 applications all include algorithmic optimisations developed over the years, most notably by Akos Fekete, who started here as a volunteer like you or I but was hired by the project because of his skills in this area. You can see his credit on the contributors page.
The ABP1 Pulsar Search application is not yet so mature, but was further optimised with the release of the x.09 variants some three weeks ago. There's a note on future plans in this direction in the science area.

One of your wingmen is the ATLAS Supercomputer in Hannover.
If your laptop can equal or outperform it - I will certainly
want one : )
