Here's another dual core Intel Mac which would participate, if a Mac client were to be made. No news after Jondr's kind offer? (I'm aware of Crossover but not too tempted to go this route at this time, although Dotsch's howto would make it mostly painless.)

If you have some questions or problems at the setup or have other questions, feel free to contact me.
The CrossOver solution has the benefit, that you could let the native MacOS BOINC client and the science applications running side by side on the CrossOver Windows BOINC setup. With the CPU throtteling, it is posible to get the CrossOver a smaller CPU usage, that the MacOS BOINC client. - I start the CrossOver enviroment for example only, if LHC has some work...

pffff here a macbook pro intelcore2duo up for running.

you know that gcc compile also fortran
http://hpc.sourceforge.net/
i guess that's not useful but you will see

The problem is, that diffrent compilers generate different results. But, if the project need 100% identical results from a WU it could be really problematic. That is the problem at LHC and some other Fortran based BOINC projects. The compiler which has LHC used is only available for Windows and Linux...

It also sounds like you have an older client. The current client only requires an email address and a password to sign up to a project that you already have a account at. You can download the latest client from here

No, it depends on the method how the user try to attach to the project. For a attachment with the commandline client you need the account key.

There is also a other method to lookup the account key :
- start the boinc client
- open a new terminal an type "boinc_cmd --lookup_account http://lhcathome.cern.ch/lhcathome $EMAIL_ADDRESS $YOUR_PASSWORD" - this would print out the account key.
- Now attach :
- stop the boinc client and issue "./boinc_client -attach_project http://lhcathome.cern.ch/lhcathome $ACCOUNTKEY"
or
- Don't stop the BOINC client and issue "./boinc_cmd --project_attach http://lchathome.cern.ch/lhcahtome $ACCOUNT_KEY"

I would be interested.

It is also posible to let LHC running with Crossover. If anyone is interested, I can write a little howto.


I have it working with Crossover, too. There are some problems with older BOINC client with the CPU counting - but not shure, if this is fixed with the newer one.
But, the perfomance is OK. A lot of better as with Parallels, and less memory overhead. - But also tested with old Parallels 2.x.

I've written a Howto for installing and configuring the Windows BOINC client with LHC@home on Intel based Macs. It's available at www.dotsch.de/boinc under the BOINC Howtos section.

With Crossover (comercial version of wine) you can install a Windows BOINC client and crunching LHC. But the problem is that sometimes the CPU time would reported to 0 seconds and the GUI RPC Port for managing the BOINC client with the manager is not abjustable in the BOINC manager, so you can only manage the client with the boinccmd tool.
I have not tried if the newer version of wine work successfull, too. After a year a go I have setup it, I did not get it working successfull with wine.

darwin (Mac os X) is not supported too and lhc@home. I don't think LHC calculation required anything very specific (no gui for example) and port for other unix should be possible.

As obove stated. It is a compiler issue. LHC used a compiler which is only available for Linux and Windows and not on other Unixes.

The problem is, that LHC uses a special Fortran Compiler which is not available on some platforms. Other Fortran Compilers would produce different results.

I talked to my boss and he/we're intending to install 11i on the k-class once the n-class is in full production.

:-)
Have a lot of fun with your the N-Class and 11i - The N-Class it's a great system.
HP-UX 11i is a very good step forward. There are a lot of good new features, better perfomance, more stable...


Thanks for the insight and I'll probably be asking a lot off hp-ux / boinc specific questions in a couple/several months.

Is there a specific project forum I should post those questions to (ie. seti or simap)?

There are forums at the SETI and SIMAP homepage. You can also mail it me directly or contact me via the BOINC helpdesk.

Thanks for the confirmation. I'm hoping to get my hands on it in about 8 weeks (we're migrating over to an N-class but I'm not allowed to boinc test it).

:-)


The K-class has 2 PARISC 180s and it's running 11.00 which according to dotsch.de (which I'm assuming is your site) has the binaries for the boinc 5.4.11 client to run. Is 5.4.11 still a viable release? Do you know if the source is available and runable for 5.10.20 on 11.00?

5.4.11 should be OK. I had a lot of problem by compiling the newer 5.8 and 5.10 sources at 11.0. There was some features needed, which 11.0 did not have. But I am still try to get it running...

The source of the BOINC client is free available. But in my opinion, a upgrade of your system to 11i - if your HW would be supported with 11i - would be better than invensting a lot of time in compiling a new BOINC client on 11.0.

You need the BOINC client and the science application seperatly. The science application do the real computing of the different project and the BOINC client only the download/upload and scheduling between different projects.

Each BOINC project is resposible for it's own science applications. So the projects supports different platforms.

HP-UX 11.0 would be supported by the SETI and SIMAP project. Both projects requires a manual installation of the science application binaries.
I think both projects are OK for a K-Class. SETI has long WUs with a very moderate deadline, so it should be no problem for a K-Class. The SIMAP WUs are short with a one week deadline. - Should be not the problem for the K-Class.
Which CPUs have the K-Class installed ?

the LHC application was written in Fortran


I heard someone was still coding in FORTRAN, so you are the one ;)

A lot of science application are still written in Fortranm, inlcuding lot of BOINC projects.

SETI has a SPE application, too.
SIMAP has a PPE only application, like Einstein.

The project admins has written, that the LHC application was written in Fortran and there are only compilers for MacOS and Windows available. If you compile the application with a different Fortran Compiler on other platforms you would get different results, which is a no go for LHC. - This was the cause why there is no MacOS application for LHC.

This behavior is OK. LHC has not permanent work. The scientists release work, when they need some computed.
In the moment there is no work available - please look at the frontpage at the upper right side.

LHC ran in the past years at the CERN in Genf and moved to UK this year.

LHC has only temporarly work. The work batches would be relased when the scientists need some work computed. This happens mostly random, but the status would shown at the LHC homepage on the upper right side.

And as I've said in the other threads it is us holding the spigot closed to try and build up a good supply, the disabled status is wrong. Garfield will have some work very soon (which may even work on Mac OSX)

Would Garfield has permanently work, or is it temporarly too ?
