I thought I might give the new opt app ago. Tried the C37 first. All 3 amd xp machines gave validate error. Switched to the A36 app and sofar still have the validate errors.
Will the optimised app only be ok with new wu?. All machines use win98 and have worked fine with the standard app.

Could you pleas try version 387.
Also look at this tread .

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

So far I've had 2 failures on one K6-2 with C37, and 1 success on the other K6-2 and a second in progress.

The K6/300 has had 2 go through OK, 1 pending and one in progress, but they were shorties.

Thanks for these infos!
I hoped that C37 will be much faster on your K6 machines...

I tried to find the reason of the validation problem.
I know that the precision of C37 has to be very near to the original.
I made a code that gave poor results, but the validator accepted them!
So, I examined the codes again and I saw there is a critical point.
Sometimes the exponent of the number format is not enough.
Probably this is the reason of the validation problem of SSE based linux application too.

edit:
exponent size of SSE -> 8 bit
exponent size of SSE2 -> 11 bit
exponent size of FPU -> 15 bit

This is an unofficial application, so "use at your own risk".

C37 uses FPU (maximum precision) for the calculation, but it needs about 4 bit longer exponent than original.
I checked C37 on my computers with 70-80 units without any error.
A longer test period would be able to determine the frequency of the faults.

I hope that S38 will solve this exponent problem.
It consists a very aggressive precision combination method to extend the precision.

Yeh that's true, I have 33 work units without any error, now I have about 20 units computed by S37a and without any error again. My question was on your (personal) recomandation.
I would like to try S38 but I can't find the link to this version.

On last but not least: thanks again for your graet work :)

So far, all my WUs have validated with C37... I'm wondering when S38 will be posted for us to try? Perhaps to the d/l thread? Again, thx for the binaries :)

It should work with 'half' wus.

I did not find the solution of this failure yet.

Probably it is independent of optimisation.

Thanks for the info. I have set them all back to the standard app for a while.

I will try one on the 387 app to see if it stops the validation errors.
