I have been pondering about this threat, but came to no publicworthy conclusions whatsoever about Phil Charmody decision.

But what I know is this: It is a true disgrace Phil Charmody gets treated...

Great page!!!

Could you post the different sobsieve executables too?

(since louie doesnt update his page and browsing this forum isn't the most exciting thing to do)

ola.

Same here :(

I have a suggestion about the sieving:

why don't we start a new threat; what we need is this:

a few (very short) ranges to test
links to all the different versions of paul's sieving program...

It is a disgrace, posting such a picture (with the accompagnied comments).

Is there a list with all primes with k < 78,557 (all about 12) online? Then it would be interesting to see the distribution of last digit numbers. Just a suggestion.

I get maximum 61000 (very sometimes 63000) with my PIII 450 Mhz, so 90K seems about right.

Not sure if there is anything you can do to speed it up more, buut if you find a trick, let us know :)

Thanks a lot Mystwalker and especially Nuri!!

Finally I understand what you are doing with "double sieving", and it is indeed useful (although sieving itself is much more important). ...

This double sieving is really hard to understand for outsiders, visiting the project only now and then. Could someone please give a short explination on why double sieving is necessary. From the...

ha!

the website is back up,

for those who haven't seen it: it was hacked, and there was a anti-war message instead.

So beware: even math projects are not safe for hackers!

Hmm SB watch out and protect your website very good, see what happens if you don't:

Apparently they feel science has a major responsibility in world peace. Of course...

Very nice indeed! :cheers:


Did you let excel fit the graph, or did you plot it using an equation.
In any case, could you give me the equation? (Maybe I'll write a hole detector :)

Cheers,...

When i start the client this message appears:


WARNING: 64 bit integers are badly aligned as qwords!

but it seems to keep calculating, so i guess nothing to worry about.

I have PIII 450...

On my computer Sobsieve again runs the fastest :->

You say you get 129K; don't let you distract by this big number!! Think of it as small, I am sure if you take...

Found it on PIII 450, (using version 9)

This is getting a bit confusing, so I repost the whole thing again:

0 - 25 Louie
25 - 50 ceselb
50 - 75 kmd
75 - 100 cjohnsto
100 - 125 Nuri
125 - 130 McBryce
130 - 150 RangerX
150 - 155...

:cheers:

Why don't you two exchange code to make one SUPER fast siever!


Btw do you guys profile your executables? I heard that can boost performance considerably too.

Cheers,

Ola

So far:

0 - 25G Louie
25 - 50 ceselb
50 - 75 kmd
75 - 100 cjohnsto
100 - 125 Nuri
125 - 130 McBryce
130 - 150 RangerX
150 - 155 nuutti

WAW that's realy great Joe :cheers:

I am currently testing
n=2114434 for k=55459
--> mod 24= 10; so i am not testing something useless :)

I hope you can do the other calculations for p=11...

Can you give an example of such a back of the envelope calculation?

Thanks!

Please have a look at:

would be awesome to have for sob!
