64,000 seconds for a Gamma- Ray Pulsar search. The wingmate did it in 6000 seconds on a dual core Celeron. (Granted, that Celeron makes my Phenom II X4 seems slow)
Picked up an S6, seems like it should take 6 days.

Just for fun I've attached a PIII/800Mhz that's doing monitoring duties here (host 7363715). I wonder how old the hardware can be and still work?

Well I have a bunch of Raspberry Pi's attached to Albert and Asteroids. The Single DM work units (one 8th of a BRP4) are taking around 113,000 seconds. And that is with the Pi overclocked and an optimised app by HBE.

Hi!
While there were still BRP4 tasks (bundle size 8) available, I had some crunched here on Einstein by a Raspberry Pi (via app_info.xml) and as you would expect from the figure MarkJ gave in the previous post, those took almost 1 million seconds to complete ! :-) .
How OLD can your computer be and still participate here? All of our Intel apps by now should require SSE (the legacy FPU is a mess to deal with), and that got introduced into the market at around 1999 IIRC.
But Bernd is also keeping the Power PC Altivec GW app alive, I guess Einstein@Home must be one of the last BOINC projects to support this architecture? I think Macs with this also debuted near the end of the 20th century.
In theory one could try to compile those searches that have open source code available (GW and BRP searches) on older machines, given the deadline of 14 days to complete tasks, some machines from around the mid 1990s might also be able to do meaningful work here. Whether that makes sense in terms of energy efficiency is a completely different matter, of course ;-)

402,064s for a GRP2 on a PIII/800MHz.
If the apps require SSE, then at least a Pentium III is required. According to Wikipedia they started at 400MHz so in theory there are older systems out there that could run e@h.

Takes quite a while to run any of the current generation WUs, but just chugs along ;-)

Wow!
The integer Flops benchmark is worse than that of my Raspberry Pi :-0 .
Glad to see it still works (the BOINC version isn't exactly new either).

LOL... And he got his FGRP task done with a day to spare! :-D
Yeah, 5.10.45 is pretty long in the tooth, but then he doesn't have much use for all the new 'Gee Whiz' features in later versions. ;-)
In fact, I would have kept my K6x fleet and PII crunching, but support was dropped a while back.
So alas, their days of searching for gravity phenomena has come to an end!
