And in the UK at least, it's a gloriously hot, sunny first weekend of summer.

It’s cool and rainy here, but at least it’s a long weekend. Do you still celebrate Victoria Day over there?

No we do not in the UK our next holuday is at the end of the month I think it is called Whit or Whit might be in August

Well, it's usual reaction on any change or feature request.
BOINC's "inertia" amount is like planet mass (or more) :D Sometimes it's good, sometimes it just annoys. Cause second happens MUCH often, it seems maybe it's time to renew tradition of custom BOINC builds with some of un-features disabled. I personally hate to mess with BOINC's code, but it looks like this way would be easier.
[Big flaw in such approach will be very small area of usage. Most of hosts will still use stock BOINC just as now they use slower stock science apps.]


Maybe you would like to mod the BOINC client today, like it truxoft or Crunch3r did in past?

We would appreciate it very much! :-)

Wishlist: RRI, CPU-affinity for CPU WUs (not for CUDA WUs), no 'UL backlog/no work request'.
Enable/disable via cc_config.xml .


I experienced/tested little bit with EasyToolz (only german).
I locked boinc.exe to only one CPU-Core and saw slower execution. boinc.exe need at least two CPU-Cores for fast execution. On my QX6700. So I guess it's the same for the CUDA WU preparation on CPU. Faster preparation on at least two CPU-Cores, or not locked.

Neither. Whitsun is tomorrow. We always used to call it the Whitsun holiday but I'm not sure whether it changed or whether that was just factually incorrect. Now it's just called Spring Bank Holiday.

My friend, we are all just users here.

Seems that few others care whether we stay or go.

A few do, but they are in the minority.

I will go my way some day, and few will notice.

Except, some day.......
They may look back and wonder where the kittyman went.

And I won't be here to answer them.

Whitsun (or Whit Sunday) is the religious festival - the seventh Sunday after Easter, related to Pentecost, according to Wikipedia.

Our matching civil public holiday is the last Monday in May, 31st May this year. Yes, we still call our civil public holidays "Bank" holidays. I wonder how that survived the credit crunch?

Edit - until I wrote that, I hadn't thought about the way that religious holidays had been replaced by financial holidays. God and Mammon?

They haven't got at Christmas and Easter yet. Hands off our holidays!

Message 998114 - Posted: 23 May 2010, 0:36:49 UTC - in response to Message 997899.  

For one year or something, I wrote in the BOINC devs forum about: BOINC V6.6.20 + big WU cache -> increasing CUDA calculation (longer calculation time).
I wrote only with a forum mod (got response). And he thought I'm a stupid guy, I felt like, because of his replies.

Nicolas isn't a moderator. The only moderator answering in there was me and I pointed you towards Trac. But to be honest, the rest of your thread was quite confusing. It still is.

Then I made a ticket, and after a short time it was deleted, because of 'useless infos'.

Ticket [trac]#898[/trac] wasn't deleted, just closed, as it had no information at all on what you were trying to say. All it did was point to that confusing thread.

Nice, you have much free time..

It's over one year ago and I'm an old man, so I can't remember all what I had done/written for one year.

IIRC, I got an EMail notification about that the ticket was deleted.

I lost the interest to make BOINC better.
I'm not a professional, I'm only a poorly PC user. So maybe I was to stupid to explain what I saw.

How it's possible that during the UL server is disabled (since ~ 46 hours) that ~ 800,000 fresh WUs were DLed? Cricket graph show ~ 10 Mbits/sec DL average.
IIRC, we had ~ 800,000 WUs, now only ~ 1,000 WUs available for DL.

The people do detach/attach, DL the 10 day WU cache, if they see they can't UL, again detach/attach and again and again..

Oh well.. I see the next database crash in the near future..

With "Results ready to send" down to practically nothing, I suspect there's either a storage or database problem. IOW, uploads being disabled may well be needed to avoid more drastic effects.

It could be the other way round. Because uploads haven't been arriving, no WUs can be validated, and so the WU data files have to hang around in case they need to be sent out again on an inconclusive validation. That would fill up the storage space, and automatically inhibit the splitters.

Either way, I'm sure you're right to say that the two effects are related, and it feeds into the discussion about whether work fetch should be inhibited whilst uploads are stuck in a traffic jam. The whole end-to-end system is balanced on a knife-edge, and relies on every component pulling its weight and passing on WUs to the next link in the chain. Intermediate storage space is finite (indeed, limited): WUs have to be disposed of to allow new work to enter the system. So there's very little benefit to be gained from modifying the client to download additional work from the server, if the server's effective 'cache', at ~2 days, is so much smaller than many people's client cache.

It was mentioned not too long ago that campus was going to do this Sutaru, It was when someone on campus cut the communications cable, they decided they were going to replace the aging cable with fiber as the copper cable would be expensive to replace I think(copper is expensive afterall) and It won't be just Seti that benefits either, Others on campus nearby to Seti It turns out could also use the upgrade in bandwidth.
