Hi, my Problem is the Following:
After upgrading BOINC to Version 5.10.13 (64-Bit version) einstein doen't load new work. It says platform 'windows_x86_64' not found.

I hope somebody knows what to do,

No problem, this a frequently asked question, so I made this thread sticky. The problem is that although most 64 bit platforms can actually execute the 32 bit science apps (there are no 64 bit apps. currently for E@H), BOINC currently doesn't sent the 32 bit apps to 64 bit platform clients. Eventually an update of the server side BOINC software at UWM will fix this. Until then, there's a workaround that users might want to try, it's described here and here.

for 64 bit linux, see here

Cheers

The server has been updated

The server has been updated and will now support automatic distribution of 32 bit clients on 64 bit systems without any manual workaround.

Those of you using the "workaround" will want to revert it, as you will need to download new apps for the next S5R3 run starting in just a few days from now.

Help! I am certainly not

Help!
I am certainly not computer illiterate as my job is in software but I cannot find my way around linux and boinc yet.

I keep on getting the "remove app_info.xml and restart ,,, " messages

I finally found a version of app_info.xml in /var/lib/boinc-clients/projects/einstein.phys.uwm.edu/

I deleted it as requested and then didnt know how to restart boinc so I restarted my pc.

Now it complains thus...
Wed 17 Oct 2007 22:10:56 BST|Einstein@Home|Sending scheduler request to http://einstein.phys.uwm.edu/EinsteinAtHome_cgi/cgi
Wed 17 Oct 2007 22:10:56 BST|Einstein@Home|Reason: Requested by user
Wed 17 Oct 2007 22:10:56 BST|Einstein@Home|Requesting 17280 seconds of new work
Wed 17 Oct 2007 22:11:01 BST|Einstein@Home|Scheduler request succeeded
Wed 17 Oct 2007 22:11:01 BST|Einstein@Home|Message from server: platform '' not found

So I cannot get work either WITH or WITHOUT the app_info.xml file

What should I do?

I think my einstein version might be 4.35 as that is included in the name of a file in that project directory i mentioned earlier

Is that the right place i should be looking in? There are other places where boinc can be found on my system but i dont know if thats from my previous inept attempts to install it or if they are legit.

No matter how much people slag off windows, linux is definitely not friendly to the inexperienced user. Windows versions would have downloaded all the files for me already and Id be laughing.

oops may have posted this in a windows thread instead of linux thread?? I dont know, its the only place the search found "platform not found"

You could look for more places of the app_info.xml file by opening a terminal window and typing whereis app_info.xml .. that should list all of them if there are any more.

But I think you had the correct one.
By resetting the project you delete all applications that BOINC has stored for this project. It also deletes any tasks you still have in progress, but at least Einstein resends lost results. As long as you don't touch anything in the client_state.xml file, you're safe.

If you are running a 64bit Linux with a 64bit BOINC version, you should now get the 32bit Einstein application sent automatically. Einstein doesn't have a 64bit science application, yet they did update their server software not too long ago that detects what client and OS you have and if found both are 64bit, you get the 32bit app.

The platform message should also be fixed by a project reset. It'll clear all the information about the app_info.xml that you had that is stored in the client_state.xml file. Only because it is still in there do you get that message.

that has not worked again.

Message 71030 in response to message 71029

that has not worked again. the client still says cannot find platform "". I am running 64 bit Debian etch linux but i'm unsure if my boincs are 64 or 32 bit. Seti runs fine on the same machine. Also i tried the whereis command and it did not find any more app_info.xmls and yet I know that seti has one in a different directory somewhere.

You might want to try

You might want to try

find / -name "app_info.xml" -print

to do a global search for the app_info.xml file in your filesystem.

When you start up Boinc, go to the Messages tab, look at the very beginning of the log.

What does it say there?

it says
Mon 22 Oct 2007 19:01:05 BST||Starting BOINC client version 5.4.11 for x86_64-pc-linux-gnu

Thanks for pointing that out.

And the find command brings up this list...

./var/lib/boinc-client/projects/setiweb.ssl.berkeley.edu/app_info.xml
./var/lib/boinc-client/projects/setiathome.berkeley.edu/app_info.xml
./var/lib/boinc-client/projects/setiathome.ssl.berkeley.edu/app_info.xml
./usr/share/boinc-app-seti/app_info.xml
deborah:/#

Does this help??
