There have been quite a number of

My computer is available 24/7 and
I have not received any. Who
decides who gets the available WUs?

I would be grateful for an answer
please.

Luck of the draw. It takes about 20k tasks before everyone gets some. Otherwise they tend to go before all the hosts can poll the server.

Usually this is not possible at this project. Tasks are normally submitted by researchers directly to an automated system, the project admins usually find out about them at the same time we do.

Or at least that is the way it used to work.

A 1 second request will still get the same tasks. Often what happens here is that the similation is unstable.

The reason the sixtrack app may not use simd instructions is for compatibility. They need identical results. They do not even use standard math libs for this reason, since those can vary for each generation of CPU.

ive been looking for some time now. its obvious that GPU far surpass CPU when it comes to number crunching. Without buying a CUDA we\\\\\\\\\\\\\\\'ll just need to wait for AMD\\\\\\\\\\\\\\\'s Shanghai.
I hope a software upgrade comes soon!

GPUs only surpass CPUs in special circumstances. They are getting better though. Some of the new ones can actually do double percision floating point math to the iee spec.

There is a good portion of tasks here that do not run to completion. Instead the beam is unstable and it crashes into the walls. These tasks are still valuable since they show things that should not be done in reality.

Read the line above that one. I bet it says something about not requesting work. The update button does not request work it just contacts the server and updates various things.

This project will not show graphics with windows vista, or with any version 6 installation of BOINC. The science application needs to be upgraded before it will work in those configurations.

This is a feature which came with the new server code recently installed. Might or might not have been consciously activated by the admins.

Michael

I hope it was activated on purpose. I have long stood behind the project's decision to issue extra tasks to increase turnaround. However I do not like my machines doing unneeded work. This feature allows the extra initial tasks without the unneeded ones.

Will there be much more new work if the LHC starts finally working?
I read that first tests will start at september, 10.

Unlikely. The work we have been doing is about designing and building the LHC. The data gained from the working LHC will probably exceed the bandwidth capacity of the BOINC project.

Post:
The LHC screensaver is one of the most attractive ones that there is.

Perhaps it's been changed/disabled recently - I have no LHC WUs at the moment.

Or do you mean BOINC rather than LHC specifically?

Al.

No it has not been changed, so it will not work with a version 6 client.

Probably not. In it's current form this project is about designing and building the collider. So once it is active there will be less work for us. The data collected is likely to have too high a data to computation ratio to be send out using a DC project.

Pure luck. This project does not have a consistent supply of work. You should have at least one other project attached so your computer can keep busy when there is no work at this project.

It is still 'pending'.

What should I do about it?

I don't think there is anything you can do about it. Hopefully the back-end update will include a validator/assimilator that will spot the old tasks and move them to the next step. I don't know if the newer versions can find the old orphans, however they do create fewer so there is hope.

This project rarely has work. It has had exceptionally large amounts of work in the past several months but do not get used to that. Due to the project's internal structure it is not possible to predict when or how much new work will be generated. The best advice for getting work is to set a small connect intraval and a large resource share.

The past few months we have had a relatively constant supply of work, as in about once every two weeks new jobs are submitted. We usually finish it in a few days though. This still is not always enough to go around.

In my opinion the best way to get LHC work is a short queue with a high resource share for LHC.

Probably one of your disk space settings is messed up. Try resetting them, be sure to put leading zeros where needed, "0.2" for instance.
