POLL: Speed Ratio of your first GIMPS box to your fastest :)
 

Glad to see there's a GIMPS forum now (I'm a little slow on the uptake...). I thought I'd run a quick poll to get some perspective on how far this project (and PCs) have come. That is...

How much faster is your fastest GIMPS machine than your first GIMPS machine? The calculator at the top of http://www.mersenne.org/bench.htm is helpful for figuring this out. Leave the test exponent as the default, or whatever :D

486DX/100 = 107,389 hours... P4/2400 = 191 hours...

~562x faster... :shock:

Wow that's ancient! I'm young enough that I don't remember a time when a 486 was good for much more than a doorstop, but then again, Í AM only 19... My first was a 333

I'm only 32, but my first was < 1MHz...

I actually had more fun back then too...

I'm 16 and I used a 486 for more than a doorstop. Like playing SimCity and Chip's Challenge... good times... Anyway, I didn't get into GIMPS until we got a PII 233. However, before GIMPS, it ran SETI@Home for like a day (I didn't even wait for one WU to be completed). After SETI came dnet which I had on for quite some time, but I eventually got bored of that (there was no point of it) and installed Prime95. I have been on Prime95 ever since :). Now I am on a P4 2328 (about 20 times faster).

I started factoring with a 486/100 and LL-testing with a Pentium 90.
Now I have a XP 2100+ (qand many other machines) and live happy in peace. :-D

Not quite true... I started with a Pentium 133 with 1,523,xxx, and added the 486/100 at office (under Win3.11) after a while.

Why didn't you add a "~128x" choice?

I think I was running an IBM processor, a rebranded Cyrix somewhere in the 133 range. I remember getting an Email from George saying that it was a horrible CPU to use for LL tests, but I told him I was willing to suffer. :)

It was about a few months later that he said to give Primenet a try for auto assignments instead of email.

So, using 486/133 as the benchmark for 1580000, I went from 64 days, 15 hrs, 28 minutes to my current P4/2.4G Northwood of 4 hours, 34 minutes.

If you had that much fun with them I have a few 486machines sitting in the basement and some very low class pentiums (under 100mhz) you could have. lol

Only 32, jebus am I the only one that thought you were in the 60's! Must be tht no job thingy that got me. lol

Anyways my slowest machine running prime right now is a 300mhz (many machines still under that but there not worth my effort) my fastest is just a P4 2ghz but I have 11 of them crunching for me.

60? I don't know ANYONE over 40 who's dedicated enough to computers and the internet to moderate a forum on a site like this. If xyzzy was 60, he'd have to be a technical genius from the Gates era...

Uhh, err, well I don't know about that one. I am 48 and have a 15 machine farm.

hrumph... um... yeah... as I chew on my foot, let me just say that when one is running on 2 hrs of sleep, they're prone to see the world in a very different light. Um... now that I think of it (and after a good long nap) my dad is a computer programmer going on 50. :surprised:ops: hmmm.... I'll try to limit my posts to times when I've had a relatively normal sleep cycle in the future...
