Hi,

there's an unusual spike on the graph representing previous week's system-wide rate, which corresponds to Mar 22nd. Any idea why?

When you start talking multiple instances of SB on the same computer, CPU affinity enters into the picture. In my experience as a sysadmin, a process not bound to a CPU tends to run longer. I've...

How come the number of total test ( as reported by Project stats) for k=54459 far exceeds that for other k's, while the upper bound is of the same magitude? Was sieving less efficient for this...

I guess I have to apologize for not paying attention. After rereding his post, it's clear that he's talking about prime powers, not primes. And his title does contain the word "variation". But in...

I came across the following post:

Does it mean that this chinese individual is able to demonstrate, directly or...

So different chipset and different CPU manufacturer from what I have. Either of two could explain why you see the improvement and I don't.

I believe the *all* portion is not quite correct. On the page they're talking
about Kt400 users. I have Apollo Pro 133A, and for me the new drivers did nothing.

Hi,

How often is ranking table in User statistics is updated? I noticed that the numbers from the "work done" line in Numeric Statistics area are always slightly higher than corresponding numbers...

k=78557 is conjectured to give the smallest Sierpinski number.
What value of k is conjectured to give the second smallest Sierpinski number? I couldn't find any references.

Thanks

Well, I just got a SEGV without ^C on Linux

[Wed Nov 20 08:45:35 2002] iteration: 250000/944080 (26.48%) k = 33661 n = 944064
[Wed Nov 20 08:49:57 2002] iteration: 260000/944080 (27.54%) k =...

SEGV still occurs with Linux client, usually if I ^C the process.
Looks like it hasn't been fixed yet in v1

I have a question about statisics. It indicates that there have been 15
blocks done in the last day by me. Either I don't understand what block
is, or this is wrong. In my interpretation a...

With the new client, SMP speedup factor is 50% on both Linux and FreeBSD P3 machines. Just to be on the same page as everyone else, here's I calculated it. 1 iteration takes 12min with 1 job...

Maybe I need to take back something I said in my previous posting. IF you're saying your cache hit percentage is high on your Celeron ( I assume you've done profiling ), then something different is...

I beg to differ. I originally also though that CPU affinity is not enforced on Linux. However, top command shows that a process runs on the same CPU it started on for the entirety of its lifetime. ...

Hi,

I did some SMP benchmarking on Linux and FreeBSD. In both cases
underlining hardware is dual P3-1GHz, 256k full speed L2 cache. Speedwise Linux and FreeBSD went had to head. The runtime...

Hi,

with Linux client I see the following screen output:

Hi,

here's what I got this morning:

I was unable to get 0.9.2 and 0.9.7 working simultaneously, but it's a minor thing. What I did notice is that there's no scalability on a SMP machine - if I'm running 0.9.7 client at normal...

Hi,

I have a dual-CPU machine running Windows. I'd like to be able to run 2 instances of the client. Right now it's not possible

Thanks

Igor

I just stopped the run, deleted a data file in SB directory and restarted, it got the new value.

Hi,

I installed the client on a new Win2k machine, and started running it as user anonymous. Then I realized I forgot to configure, so I stopped and changed the name to mine. Then it restarted...
