How long until Einstein gets done with a unit?

(moderation:
I joined Einstein while Predictor@Home wasn't sending out work units. P@H is now sending out work units. I have told Einstein not accept any new work units. How long until it gets done with the one it is working on?
Due to how BOINC is designed, if I have my computer work on two units (of one or two projects), it eats up 100% of my CPU. That is totally unacceptable thus why I can only crunch for one project at a time and I choose P@H.
Now if Einstein will forever work on one unit, I'll suspend it until P@H has another lull in work assignments.

From looking at your recent posted results, it appears Einstein units take between 8 and 9 hours to process on your computer.

EAH is grateful for the time you have donated. Your contribution is appreciated. If you look on the work tab of your BOINC Manager window you should see the estimated time to completion.
Actually BOINC is designed to take ~100% of the idle cpu cycles on your computer, irrespective of how many projects are actually running. I notice you have a HT cpu so I presume you have 4 results in progress (2 from each project) at any one time and that this is troubling you? Please be aware that BOINC runs the science apps at very low priority and is very good at shutting them down when your machine needs to do its normal work. It is quite non-intrusive and safe to let BOINC do this, even if you have compute intensive normal tasks needing to run without disruption.
I might be misunderstanding you but are you saying that you want BOINC to only use one of your virtual cpus and leave the other one completely free?
You can set EAH to get no new work and it will finish up what it has already and then stop. It wont keep working forever.
Cheers,
Gary.
RE: ... if I have my

I think I may have misunderstood this part of your message. Are you really saying that you have your preferences set for your HT capable machine so that only one of the virtual processors should be used. The number of processors to be used can be set in your general preferences. And further are you saying that having two projects sharing that single virtual cpu is resulting in a higher cpu usage so that is unacceptable? For my own understanding, I'd be interested in knowing exactly how that preference is set.
By the way, I notice EAH has finished all outstanding work on that machine. Thank you very much for your contribution and we hope to have you on board again sometime soon.
Cheers,
Gary.

If I allow a BOINC program to work on more than one unit, it uses up 100% of my CPU. Yes, I understand that in theory it is to give way to what I'm working on, but in reality, it hogs my machine and slows it down. This thread at P@H discussed it:

Ah, I see P@H still doesn't have work units to hand out. Switching back on Einstein.

Scott, Welcome back!!

Scott,
Welcome back!! Good to see you again :).
I had a good look at the PAH thread and all I can say is that Heffed's advice is spot on. Whilst I'm actually an AMD fan, I do have an Intel box with a 2.6gHz HT cpu which would be less powerful than yours. It runs EAH and Seti on both virtual cpus all the time and I honestly can say that I can't notice even a hint of a slowdown. When I look in taskmanager, just like you reported, I see 50% and 49% for the two science apps that are running. Whenever I work on that machine it feels crisp and fast like there is nothing else going on.
I know this isn't helping you but there has got to be some other reason if the slowdown is that noticeable. I'm entirely clutching at straws but could there be some "hidden" background processes or services that are running on your machine that don't show up in taskmanager but are running at high enough priority to make your life miserable? My knowledge of malware is not good enough but maybe someone else who has experience with these things might like to chime in here and offer suggestions. Your problem should be fixable.
Good luck!!
Cheers,
Gary.

I have three friends that are professional computer geeks and they read the thread then did tests of shutting off this and that. End result was that it was BOINC that was causing the slow-down. And it was not just noticeable but annoying. So BOINC gets half my CPU and all's fine. :-)

Glad to see it's sorted. :)

RE: I have three friends

You may modify your preferences. I have an Intel 3 GHz CPU HT and 1 GB of RAM, and I set up EAH to use only 1 CPU ('cause WXP sees it as double-processor). It works really fine and it doesn't slow it down while I don't do too many things on it, and it can be stopped if having other more complex job to do.
