1) Message boards : Number crunching : Want: EXIT_TIME_LIMIT_EXCEEDED to happen faster (Message 1605470)
Posted 23 minutes ago by Profile HAL9000
Thanks! This worked. I am setting up the win7 task scheduler to perform this function. Two tasks that were hung actually completed successfully after restarting. One was hung for 5 hours. I noticed that the run time reported by the project did NOT show 5 hours, only the normal 40 or so seconds. Apparently it did not exit properly after successfully completing.

If you suspend a BCU tasks it starts over. I don't think they checkpint because when you are running one it is doing stuff over the internet.

With that kind of processing rate. One of the specialized ASIC miners that runs ~100GH/s & uses about 100w mining Bitcoins for me would net about $5.94/yr after factoring electric costs.

Does that also account for the 10% rake that BU is taking off the top of the total mined (not the net), and any pool fees that aren't included in that 10%? :-)

Bitcoin utopia uses various coin types for their campaigns. Some are more cost effective than others from what I have read. With Bitcoin being one of the hardest/most costly to mine. It looks like the primary type for the SETI@home campaign is Peercoin.

Peercoin certainly looks like it might be more economical to mine but, as with just about everything in this murky cryptocurrency world, it's kind of hard to pin down anything concrete. A quick search turned up a Peercoin Mining & Profit calculator, but I have no way of knowing how plausible the estimates are or whether there's actually any way to tie those numbers to what goes on over at Bitcoin Utopia. It gives me a headache trying to make sense of the intricacy of it all! ;^)

With the project you are not collecting any currency of any kind.
I was using the quoted figure of 0.14 US dollars a month in my calculations figuring mining for profit. Not for Bitcoin utopia. As with any project it is all an expense.
At the rate of $6/yr it would take about 13 years to pay for the hardware I was referring to at a cost of $80 just to break even mining Bitcoins. It looks like it would take about 3.3 years to break even for Peercoin with that same hardware.

The boards are up, the server staus page shows we are down and yet I just reported 2 MBs and got rewarded with a resent AP V7. How odd.

It isn't very odd for the Server Status to be behind following an outage. Given it only updates every 10, or sometimes 20-30, minutes.

Everything looks rather normal.



Some things don't seem right though, my RAC hasn't changed all day, despite no WU's being crunched. And there seems to be splitters working on Astropulse, but its creation rate is 0/sec? I still haven't had anything since Wed, but maybe soon....maybe ;-)

P.

I think they may have disabled or changed the built in degradation part of RAC. Normally it should drop at least once a week, but I have machines that have had their RAC flat for ~3 weeks.

There is MB work being split, but no AP work. There are 9 complete AP channels on one tape, but those were done weeks ago.

Does anyone know of a conversion from wu to bitcoin to dollars to Seti?

Although it doesn't directly answer your question, I found this message over in the Bitcoin Utopia forum:
It's possible to give some estimates using this Bitcoin Mining Calculator.

If you have a 1 GH/s bitcoin miner and you are running it 24/7, you are mining about 0.00038 bitcoins a month. That's about 0.14 US dollars a month.

I believe that only dedicated ASIC hardware would meet or exceed that 1 GH/s hashrate that he mentions. For GPUs and CPUs, there's a somewhat outdated chart in this Wiki. However, I think the first paragraph is about all most of us need to read:
Due to the rising hashrate of the bitcoin network caused by the introduction of ASICs to the market, GPU mining Bitcoins has become impracticable. The hashrate of most GPU units is below 1GH/s, and as of 2014, some single ASIC units are able to reach speeds of over 1,000GH/s while consuming far less power than used by a GPU.

So, my own choice is simply to save the electricity and dedicate a percentage of the money I'm saving during this outage directly to the project. As always, YMMV. ;^)

With that kind of processing rate. One of the specialized ASIC miners that runs ~100GH/s & uses about 100w mining Bitcoins for me would net about $5.94/yr after factoring electric costs. So the other coin types would be a much better choice.

Looking at the other routers it is campus wide. No stats for anything from that time forward.

I'm sure that we will start getting new WU's before midsummer 2015, or at the very latest December 2015...

Until then, at least we have the message board, so we can whine and complain :-)

That goes on when we have work as well. So everything will be the same as normal!

Since the conversion rate constantly fluctuates, like currency exchange rates do, it is unknown. Once a campaign is finished they could provide the details for 1 task = 0.00001 BC or such.

http://en.wikipedia.org/wiki/BOINC_Credit_System

This is the way the boinc credit system is designed.

In short, if a computer does 1 Gflop/s it wil give you 200 cobblestones per day. Giving a fixed number of cobblestones to a Wu is possible if you know exactly how much flop's a Wu takes.

To be fair, as seti is the first project which used boinc and the new program's were developed with each other, the seti project is one of the few who's giving the correct amount of cobblestones.

The reason some projects give more is because of the people who do this solely for the credit's will go to the project which give's the most per time spent.

The number of credit's a machine can gather is therefore project specific and that's the reason I only compare machine's with each other which are doing the same project.

It's the stats sites who are making a mess of it adding the credits from multiple project's and comparing those. This could only work if all the credits are calculated the same.

Credit allocation is actually based on this now.

The easiest way to unstick GPU tasks is to bounce the GPU at an interval.
In the early days of doing MB work on my ATI GPUs I would run this every few hours.
boinccmd --set_gpu_mode never 10
That way BOINC would suspend GPU processing for 10 seconds & then resume.

For Bitcoin Utopia you may want to run that every 10-15 min.

My 120GB SSD's show up as 119GB usable if that helps.

Cheers.

Thank you your information and is very helpful.

I would expect it has 500,000,000,000 bytes to use, or 465 gibibytes


Thank you for this information. It is all always interesting to see how much hard drive is actually taken up before you put anything on it. It would be nice if drives actually stated how much usable space instead of the actual size of of the drive. I know that will not happen

No space is being "taken up" as you stated. It is more that the storage industry uses a different standard than the ones used for other measures of capacity in a computer. The good thing about standards is that there are so many to choose from.
If you want to quickly convert from GB to GiB you can just divide by 1.074 or use 1.1 for TB to TiB.

I'm with you. I think you may have slightly misunderstood my question. What I was meaning is how much space is available on the SSD before you installed anything? I'm assuming for a 500 GB drive it wouldn't be 500 GB that you can use

I would expect it has 500,000,000,000 bytes to use, or 465 gibibytes if you prefer.

At first I was like "wow that is running hotter than my i5 at 100% load", but then I saw it was an AMD and I understood. :P

I was setting up an older system for submersion a few year ago, but then I bought a new place & haven't bothered to venture back into the idea.

Normally just using the Intel headers, if you're not using their RAID capability, any ROM drive should be fine in either of the last 2 channels. ;-)

I know that they can be prone to causing problems in the 1st 4 when attached to them (most good mobo manuals will state the best position for ROM drives anyway.).

Cheers.

Interesting. I have always put my ODD on SATA1. With the boot drive on SATA0 & the RAID setup on the remaining SATA headers.

Don't hold your breath for GBT data. It will need thorough testing on the Beta site before it is released in the wild.

Edit: I'm sure Lunatics will have an app for it if needed before we see it here.

I would expect GBT data & app testing on Beta before it hits main.

In last 24 hours 32 units received. At this rate, a little bit over week left.


I think you can add another 25 days to that with all the time outs coming up fairly soon calculating by the last time I got a V6 resend...


I know, that's why I did say "At this rate".

There is hosts like this HAL9000:s MAC, two task still left and if it's running 24/7 it should have reported those two remaining tasks already. But it hasn't.

It normally does run 24/7, but we had a power outage. So it was off for about a day. About 12 hours left to go on those two tasks.

Not sure about that...

...approx. 10 minutes ago while attempting to post, got this: - Fatal error: Cannot redeclare boinc_real_escape_string() (previously declared in /disks/carolyn/b/home/boincadm/projects/sah/html/inc/db.inc:177) in /disks/carolyn/b/home/boincadm/projects/sah/html/inc/boinc_db.inc on line 710

I was getting that site wide about 90 min ago.

This is a neat idea. The Thermaltake v21 can be combined with a 2nd case to make a larger case.
