Hi,

long time no see.
Was away for a while, now want to restart crunching.
I have a HP Proliant G4 Server with Ubuntu Server 10.04 running in my little office.
What is the most efficient way to get a max. output to start crunching with the server?
Which version is best to use? Optimized?

Any help appreciated.

Regards

As always you want the Lunatics optimized apps. Install them, set it and let her run.

That's correct for Astropulse v505, there are both 64 bit and 32 bit Linux apps available built from recent rev 411 source code.

For SETI@home Enhanced multibeam (MB) get the appropriate AK V8 build from Crunch3r's pages.

Some care should be taken when combining the needed app_info.xml sections. The BOINC anonymous platform documentation provides a basis, but I suggest asking for help here for anything which isn't clear.

Well,

so far I got the regular boinc-manager running on my server via command line.
It´s v5.28 through apt-get install. Can I update to the last version?
There´s no gui on the system, because it´s a server :-)

I´m not very actual in the progress of crunching involved.
Do all the opt. clients support seti and astropuls?

BTW there are three more servers in the rack I could reactivate to crunch.
So this could be a small crunching farm.

v5.28 is the current stock Linux 64 bit SETI@home Enhanced application. See http://setiathome.berkeley.edu/apps.php for stock version numbers (but ignore the Astropulse v5 section, there will never again be any work for it).

The version of BOINC is very unlikely to be 5.28, Ubuntu keeps more current than that.

Because BOINC itself is a client/server arrangement, we usually refer to S@H and Astropulse as science applications to limit the confusion. They are separate applications which do different analyses of the data recorded at Arecibo. To do both kinds of work you need two applications, running stock you'll automatically get the Astropulse v505 application when work is assigned which needs it.

If you switch to optimized applications, the project will only send work for whichever application[s] you have installed. There's no automatic delivery of the applications, so you'd need to watch for needed updates. But the optimized CPU applications are significantly faster, so many users decide that extra effort is acceptable.

The small farm idea is certainly interesting, but understand that electricity isn't free. Be sure to comply with the first rule:

Run SETI@home only on computers that you own, or for which you have obtained the owner's permission. Some companies and schools have policies that prohibit using their computers for projects such as SETI@home.

                                                                Joe

Yes, many of the BOINC clients also have a complete commandline interface, which is described in the BOINC Wiki Boinccmd tool page. The actual recommended version is 6.10.58

To prevent some possible confusion about BOINC clients here is a hint :
The BOINC Client is not doing the crunching. It is responsible for starting the applications (e.g. setiathome or AstroPulse) and communicating with the servers in Berkeley. The applications do the crunching and therefore are the ones to get optimized for faster speed or to run on different platforms.

BTW there are three more servers in the rack I could reactivate to crunch.
So this could be a small crunching farm.

You are responsible for what you do, your choice.

Thanks for that first infos.

I´m still getting all collected to get a best running system on that HP Proliant G4 servers.

I´m aware of power consumptions. Thanks for that hint.
After been employed for several years I´m starting my own company.
As an former CEO I have the abilities to do this just for fun, even in financial.

So please don´t hesitate to write me how to optimize my installed hardware for crunching.

Heh, must be nice....so you're the jerk I complain to right? Just kidding lol. If you have the money I would get one machine setup and working like you want and then kick the other on setup the same way. I mean if you can afford it why not??

That´s what I want to do with the servers I still have.

Ok, I know I could buy a newer and faster one to set the others obsolet, but hey that´s my "sport". I want take the best out of the "old ones".

So I´m interested to get the best out of them.

I also have the AK V8 builds bundled with the recent AP r411 app.

Well,
optimizing the system with command line only seems to be harder than expected.

I tried to get the linux64 sse2 optimized client running.
Installation went well, but...

After downloading workunits got only lots of checksum errors and

output .... absent

Every Workunit became error status.

Any help on that or what may´ve caused it?

You mean the application of course. Can you give some more detail about the cpu you use ? (e.g. more /proc/cpuinfo)

Did you allow the applications to be executed ? (e.g. chmod +x filename)

Note that pni stands for "Prescott New Instructions", Intel's original name for the instructions later called SSE3. Upgrading from the SSE2 to SSE3 optimized applications should give another few percent improvement on that system.

                                                                 Joe

Thanks,

can you give me a figure on how much that could improve crunching instead of sse2?

Very little, at least on my Opteron.

Not only execute, but also make sure the project directories are writeable by seti, boinc and the virtual user that is running the apps. On Ubuntu 10.4 & 10.10 these directories sit in the structure /var/lib/boinc-client

SSE3 apps should be nearly always faster. Only on AMD k8 architecture cpu's i have seen SSE2 sometimes faster. Your's is Intel, so go for SSE3.
