1) Message boards : Number crunching : Planned outage for BOS and ESEA (Message 16193)

I've spent the last few days checking everything was working correctly, and it seems so. This is what happened Sunday:

Around 10 am local time, the database drive stalled once again, and I shut down the system, knowing I was going to correct things later.

Around 3 pm local time, I had moved everything to my work area, and wanted to start up to test everything would work fine when attempting to do the drive switch. But now the database drive box didn't start at all - no fan, no light, nothing. The other one seemed to start as usual. I thought it might be the power supply, so I switch to the other power supply - this time the box started, but I really didn't like the sound, so I turned it off quickly. The other box didn't like the power supply from the database drive box.

So, now I had two drives that I didn't know if I could even get working. Anyway, with two drives to switch and only two drives to replace them, I could wave goodbye to my RAID plans. The only hope I had was that it was the external boxes that were failing, not the hard drives themselves. And it turned out to be just that. So after I had copied the database drive successfully, I made the sites available again while copying the other drives - before moving things back where they belong.

For those who haven't read the BOS RSS feed, the BOS message boards or the ESEA message boards, here some info:

The hard drive containing the databases has been giving trouble these last few days. It is close to give up. I have two hard drives which was planned to be used as a replacement for the boot/system drive, but this is more important right now. So this weekend I will spend some time replacing the database drive. I will try to build a RAID with these two new hard drives, but this may take some time, as it is the first RAID I've ever made. Keeping all data/programs completely intact during the process is an extra task, and may make it take a bit longer, as I don't have a third clean hard drive to save things on. But I'll do my best to do this as fast as possible. If all things go wrong I have back-ups.

So, just so you know, the BOS site and services and the ESEA site will be down for a while this weekend.

ha, I might have looked greedy :D By accident, due to changes in cache size, suspending/resuming projects, and an unfortunate timing of scheduler requesting work, I ended up with a huge bunch of wu's that I new I wouldn't be able to finish in time - and if I tried other wu's wouldn't finish in time. So I had to abort a large amount of them. That would make others able to grab some - only side effect would be that they might have to wait for a re-issue

ESEA (Earth Space Exploration Agency) is looking for more Agency Scientists.

It is obvious that research is abundant, and our supercomputer can't keep up with the current amount of processors. So, the Agency is looking for more staff and the processors that come with this additional staff.

Currently the supercomputer is operating in the mid 40 GFlop range, and we need at least 100 for the time being.

There are an unlimited amount of positions vacant - just plug-in your processors.

Oh my... My farm has never grown bigger than two *sad* For a short while the two consisted of an AMD 486sx 40MHz and an Intel P100 *lol* That was back in end 1999 to beginning of 2000. And then I when back to one again - a P233 first, then an Athlon 1600+. The Athlon is still going, although only on about 25% of the time. So you could say my farm currently consist of 1.25 PC's *lol* - the 1 is my Athlon 3200+

I do have plans for when I get more space and money.

Welcome all :) I know many have been waiting patiently and anxiously to be part of this project - personally I've been looking forward to this for a while as I know some of you from other projects and like to see even new ones around. That's good for this project, and good for BOINC as a whole :)

So, welcome and happy crunching :)

I suspected as much with the estimates. In the end though I guess the uptime percentage messurements for each host are ment to take this into consideration, at least to further make sure clients don't get more work than they can handle in time.

Markku:

"Increasing quota is problematic in the sense that some older machines can then download too much work at once (and possibly never finish it)"

Isn't deadlines, benchmarks and estimated cpu time used to prevent this?

If they end up with a list of 20k people, noone says they HAVE to let all 20k in the minute they want/need more participants ;) It could work just like a FIFO buffer - first in first out, just in this case it would be more like FOFI - first On the waiting list first In the project ;)

good thing I checked this thread - whn I came home this evening I saw a bunch of these download errors - and wondered if my internet connection had been severed for a while after starting downloading. No need to worry then :)
