Well, I can tell you it

Well, I can tell you it doesn't work for a K6-2 running 9x.

Moral of story:

1.) Make sure you exercise some caution before you slipstream it to all your hosts. Related to this, since this opti is essentially an RE hack, that might explain why Dr. Allen wanted to run it through the testing loop before releasing it as an "official" EAH app, because of problems like that.

2.) To announce to the EAH community with a potential CAYS link, with no explanation or even a link to a site to allow anyone to see what's up about it is irresponsible, regardless of how clever the work is.

3.) My gut feeling is Dr. Allen is not going to be too thrilled about this development.

Perhaps a low level link was intentional to limit access to only the most "savvy" users who would be able to deal with any problems, but nonetheless, I am just as irresponsible in using the application. No one is forcing me to use it....

exactly as with any optimised client there is always risk and most users know that

I would like to know how Dr. Bruce feels about the optimized app before installing. I know it is validating and things, but getting a better official word makes me feel better.

So, is it good for us to use?

I don't know about you, but it feels damn good to me :)

such things just should not be writ so please destroy this if you wish to live 'tis better in ignorance to dwell than to go screaming into the abyss worse than hell

A36

I tested the very fast application on my Intel P4 3.2 GHz with active HT.
Crunching times nearly the half of the original Albert.

But, the temperature (copper-core oft the cooling unit, checked with Digital Voltmeter and VCR ) will be nearly 10 Degrees lower!

Many Thanks to You. You have done an excellent work!

Bruce's looked over the code

Bruce's looked over the code changes for the optimization, praised them and promised new apps for all platforms using them, so I think any objection would be pro forma at worst.

The drop in cpu temp's probably related to the fact that the biggest algorithm change removed most of the slow division ops, so you're not using that part of your FPU much.

I would like to help on speed optimization, but i don't know what is the way of it. Probably i can put my code on a webpage, but i think it would be not legal. I didn't get any e-mails in connection with legitimacy.

Something made him change his mind. We know from earlier in this thread that he has shown his optimized client to Bruce. His post only contained the link to the application. No installation instructions, so you need some familiarity with BOINC file structure to be wiling to install it. Look at the timestamp of his post.

If you wanted to release a test application, isn’t just before work Tuesday morning an excellent time to do so, if you want to keep an eye on things. (just before 8 in Germany)
The sent back result contains this massage:
�Optimized by akosf (A-36) --> 'projects/einstein.phys.uwm.edu/albert_4.37_windows_intelx86.exe'�
If Bruce made a post wanting us for some reason to stop using this client, wouldn’t most of us reading this thread uninstall it so fast it would make a gravitational wave even SETI could detect. :)

Is that the X-files theme I hear in the background? :)

Then you're really interested in a subject, there is no way to avoid it. You have to read the Manual.

PS has anyone tested it on an amd platform? I've got it running on my a64x2 and it hasn't crashed, but it'l lbe afew hours before I've got validatable results.

Be that as it may, and I am implying no malfeasance on Akosf's part in reverse engineering Albert, or malintent in his "obscure" test release. The fact remains that if EAH wanted to have app version variety in the wild they would have made the source code freely available and encouraged folks to have at it, like SAH does.

I took Dr. Allen's prompt and positive responses as an indicator he found the proof-of-concept app had merit, but we would have to wait until as many of the ramifications of full scale release could be evaluated and addressed.

I've completed two and two halfs (units started under old finished under new). One and two halfs have validated successfully, the 4th WU is waiting on someone else, and won't be validated for annother day or two.

I've gone from 3:45+-15 per large WU to 1:40/WU.

CPU temp hasn't deltaed more than a degree or three at most (I didn't check beforehand), but a64s aren't blastfurnaces to begin with.
