Thanks, Nereid. I think I couldn't have done it without my machines...

LJ, Depending on how much hands-on access you have with that box, a tip mentioned in the E@H thread was to detach and reattach to the project after it runs through the day's WUs; that way you get a fresh quota of 32.

Obviously, it's a lame workaround, if at all in your work situation, and I'm sure E@H will eventually have to change the rules, or at least find a way to funnell the longest WUs to the fastest PCs.

@Udo:
There was a response to my post over at E@H quoting the Wiki:
Quote:
The BOINC Client Software communicates with several Servers in the course of getting work and returning Results. All communication uses HTTP on port 80, so the BOINC Client Software can function through Firewalls and Proxies.
Remote access, via BoincView or BOINCmanager, does use port 1043, but he says the actual core client communication with the servers is all over port 80, specifically so it won't be blocked by firewalls.

So if this is correct, you would not be able to monitor your work machines remotely, but could leave them running E@H autonomously. Would this apply to your situation?

I'm sorry I didn't realize this earlier, I knew BV uses 1043, and it is the only port number I've seen mentioned concerning BOINC, so I just assumed that's what it used for everything.

Yeah, I think repeat instances have given us a team boost despite participation being down from what it once was. I just noticed that we posted our second-best day as a team (and climbed a spot):

14000+ for a day is indeed awesome Wolv, and shows we still have more "RAC upside." Mine keeps growing even after using the new apps for 2+ weeks -- 165 is now 423.
______

Here's the latest word on the daily limit from Micheal Roycraft, who I believe works with E@H:
Quote:
Hello, Ken.

You could scan through some of the recent threads for one on just this subject, it has been considered, continues to be considered, in fact.

Long story short - the servers that E@H has (at this point) cannot accommodate so much increased traffic and size in the database; they will need an upgrade before the daily limit can be doubled again. Otherwise, such an obvious move would have been made almost immediately, because Akos' apps soon made E@H aware that such a doubling was needed. I personally think that the "short-handed server" situation is in large part responsible for the delay in making Akos' work "official" and downloadable from the project site, as well.

Michael R.
(my bold)

So they are definitely aware of the situation -- maybe PayPal is next for them? OTOH, this implies that the relatively few of us who do use akosf's apps will continue to have a large advantage.

(I admit to not searching first over there, but I posted in a current thread called "Running out of WUs " which seemed close to topic? And searching sucks on BOINC forums. )
_______

If Wolverine or Nereid don't mind, I'd like to make a fresh post here pointing people to this discussion, for those E@H members who are no longer reading this thread. On his forum, azazul suggested such a post be made in General Science, but as this is specifically about Einstein@Home, Astronomy seems a better place? And recruiting posts made in GS in the past have not been overwhelmingly successful.

After all of the talk about optimized applications, I decided to look around for other projects. The only ones I have found thus far are for SETI@Home. There are three sites hosting optimized applications, but the one that I used and was highest recommended as far as I could tell is here. The other two are here and here. If you cannot find an optimized application for your specific computer on one of the sites, check out the others as well, some have applications the others do not.

I installed one of the applications on my slow laptop and it takes 1/3 the amount of time it did before to finish a WU. Unfortunately, I was unable to install it on my other computers running SETI@Home, because FreeBSD is only supported for Pentium III's.

We already have a pair of stickies devoted to the topic; since this one has been pretty active, I'm not sure additional postings would receive much more attention from team members. Maybe Nereid has an idea or two?

Edited to add: I posted an update on this thread, just in case.

Yea! We are over 3 million and our RAC is higher than ever.

I've not had the problem with the smaller WU's being sent to my 4000+ recently. As a result, my RAC has moved over 1300.

Azazul, can you e-mail the entire E@H team about these new apps? I know that shortly before Ken brought these to our attention I was passed by PeterFab. Since then his RAC has actually gone down slightly so he may not know about the new apps. I'm sure he is not the only one.

I can save Azazul one email. I already run akosf's new app. RAC went from ~150 to currently ~670. Only one WU failed.

Good idea, I will put something together and email it to all E@H and S@H participants, since those are the only two projects I know have optimized apps.

Good to hear from you Klausnh, it has been a while.

Thumbs up I second the email idea

I belatedly echo Udo's congratulations to the team! In addition to passing 3M, our RAC has gone to 33rd, catching up with our overall position, for the first time in a long while. Having just a few more users crunching akosf's apps will definitely push us higher, so I also applaud Laser Jock's suggestion for the email.

You can divine who is and is not yet "akosf-ed" by looking at BOINCstats. If you click the tiny little graph icon () to the right of a person's listing, and scroll down to the RAC graph you can see what is known as the akosf spike: Here's Klausnh's, for example -- and I echo the warm welcome back Klaus!

Among other top users, I noticed Sarah MacIntyre has joined the party; but I'm not sure if anyone else has, so an email will definitely help reach folks who aren't reading the thread these days.

azazul, you might also mention that the app works well for older, slower machines, so people who've stopped running E@H (and maybe seti?) might reconsider. I put S39L on an old Pentium III at 550 MHz, and it runs great, showing the by now usual tripling of speed. I had never considered running E@H on that slow machine, but it is now running five or so BOINC projects without a hitch. Incredible.
________

Laser Jock, I haven't recently gotten one of the fast WU master files; it may even be possible that they've stopped sending them, but thinking about it, I would guess that the 32 WU limit might not be too much of a problem even so: each file has only 25-50 WUs (AFAIK, I've never been sure of the exact number) and so at 15 minutes per WU, you would whiz through the file in a day or two, and then in all probability get a longer-lasting file to crunch, so your actual downtime would be relatively small.

The BOINCstats homepage, also notes that BOINC users have accumulated over 10 billion credits; and the BAUT team is now ranked 166 out of over 46,000 teams overall.

Thanks for the welcome back. I haven't stopped crunching since I joined over a year ago. But I've just been too occupied with other interests to post much.
Last fall I was given a Dell laptop with a cracked screen. After some investigating, I discovered I could connect a monitor to the laptop and bypass the screen. Initially, the laptop would shutdown after about an hour of processing. I used an old cookie baking pan as a heat sink and the Dell has been running almost 24/7 since.
I've also switched an old 266 Pentium II that was running LHC@home to einstein. It takes about 7 hours to complete a WU with akosf's app. So anyone with a slower CPU can easily run E@H.

I'll add my congratulations and thanks to Udo for his support of Einstein@home and his 300,000 cobblestone contribution to the team.

last weekend I succeeded in changing the last 2 servers to akosf's optimized application. These servers are located 40 miles / 60 km away, and are running most of the time really unattended...
Thats only possible with E@H!
Now the RAC of theses servers will also climb a little bit...

I also followed Ken's advice and downloaded 2 CPDN workunits for my 'big' server at the office. This keeps the CPUs busy over the weekend.
Unfortunately the filesize of the project is very big (> 500MB). So I was not able to take the results home for uploading.

Last monday I got my broadband cable modem (6MBit downstream) and was able to download the CPDN data from the office server to my home office.
Therefore I suddenly got nearly 8000 credits at CPDN (for 700h CPU time).

happy crunching....
Udo

Every little bit will help, I recently added a few more computers, but they are not very fast, so I probably won't see much increase.

I noticed a sudden jump in our stats, I tracked it down to your account but could not figure out how you could suddenly get over 700 RAC. This explains it.
