[quote=mdettweiler;156078]Hi all,

As David just recently posted in the LLRnet servers thread, he's started up a new server on nplb.ironbits.net port 8000 (IB8000) loaded with n=350K-351K for k=1005-2000. Everyone can go ahead and shift their machines over there as soon as they're ready. :smile:

I'll set up an official drive page here within about 2 hours. I'm going to hold off on moving CPU's over...may move 1 quad a little later tonight. Ian and Chris already have the n=350K-351K range at ~10% complete in just 4 hours putting the ETA on the server range at only 40 hours if no more resources were added.

Based on this, what do people think about running the entire n=350K-352K range on port 8000? It would save us admins a little time. :smile: At the above rate, we would complete n=350K-352K in 80 hours or < 3.5 days. If I add a quad, then less than that.

Max, if there are no objections, feel free to load up n=351K-352K in the server also.

David, I haven't read many of the posts yet from the last several hours. If you haven't done it already, due to the high-priority of the effort, please make the JobMaxTime 1 day. After we dry this, then future ranges for port 8000 (if we decide to use it) can go back to the usual 3 days.

Thanks everyone for pitching in! :smile:

Moved 4 cores to IB8000. Going to bed now, Happy New Year to all!!

With Carlos now on there, we're already 13% complete with n=350K-351K.

Here is what I'd like to do: I won't post any manual files in the new drive page. If anyone wants a manual range within the range of n=351K-352K, please tell us within 4 hours of this post or by 7:30 AM GMT on Jan. 1st.

With the speed of the server, there is now one stringent requirement: All manual reservations must be completed within 3 days. Please plan accordingly.

We're going to shoot for < 4 days for n=350K-352K so everyone can get back to their sieving and running the other drives.

If there are no takers, I'll send n=351K-352K to David's port 8000 and we'll run the whole n=350K-352K range on the server.

One more thing: An n=350K prime will now come in 4980th place on top-5000 so we started this none too soon! :smile: An n=352K prime will come in at 4859th place so the pressure is off after this small effort is done.

Well, I was originally planning to shift my quad over to IB8000 sometime today, but at the rate we're going, it looks like it won't be necessary after all! :smile: Given that, I'll keep it on C6000 where it's been for the past few days (my plan being to stick with that server until it reaches n=1M on k=341).

Maybe I'll toss one core of my dualcore on the server so that I can still rake in one or two of those top-5000 primes that I had been hoping to nab easily with my quad. :smile:

As for sending n=351K-352K to IB8000: okay, that sounds like a good plan. :smile:

File coming at you in the next 15 mins.

For the record: Reserving n=351K-352K for David's port 8000.

It is now. It's hard working with those huge files. The one I sent you is reasonable though.

Where are we testing the n-area from 50k to 350k?

thanks,
nugget

That hasn't started yet. When Ian is finished sieving P=1400G-1800G in the sieving effort, we'll start that drive. I think he said his ETA was Jan. 5th on that.

We started this drive early only for the small range of n=350K-352K with undersieved files to put any prime for n>350K on the top-5000 site. When the current range is complete, this drive will be suspended until the sieving effort is done; likely ~Jan. 20th.

em99010pepe 2009-01-01 12:38

If we all move more cores to IB8000 we can manage to finish n=350k-352k range within 24 hours. Rally time?
