I have a mate, that I have tried to explain it to(via email) but just seem to get it right..
Anyone got a step by step installation guide to install the Op'd client.
He has many computers and I would love to see him with all of them, on the Bang for buck train. You know get more w00t's happening

Hi Rusty.
Go to Crunch3r's site at this link and pick the appropriate operating system (-doze, linux, 32 bit, 64 bit etc.) for the matching application list.
http://calbe.dw70.de/seti.html You/your friend also need to know what specific type of CPU you have since there are different aps to match the capabilities of newer vs. older CPUs. If you aren't sure, you can right-click on My Computer if a Windows system. You can also install CPU-Z http://www.cpuid.com/download/cpu-z-143.zip which will tell you.
What you are looking for is the type of SIMD instructions your CPU supports, MMX, SSE, SSE2, SSE3, SSSE3, SSE4 etc.
For maximum benefit, you want to choose the application that matches your OS flavor, bitness, & SIMD support.
If this is intimidating, just let me know and give me as much info as you know about your computer/CPU.
Otherwise, just download the application zip. Inside are the necessary files and an instructions txt file.
It is VERY easy. ;)
Have fun!

I have mine op'd... I have got my mate to do it.. But all turn out to be COMPUTATION ERROR.. My friend has reset SETi through BOINC and restarted the computer..
I wish I could just pop around
-
Turns out my mate doesn't have SSE3, so this could be the reason for the errors.
Well from what I can tell from the attached, can someone explain what the other error is. Maybe that will be fixed when the SSE2 is installed

Looking at that copy of the messages tab the app_info.xml file is missing in the projects/setiathome.berkeley.edu folder.
With all windows optimized applications that is:
- A app_info.xml needs to be copied to the projects/setiathome.berkeley.edu folder
- Replace_with_Name_of_Optimized_app.exe needs to be copied to the projects/setiathome.berkeley.edu folder
- Replace_with_Name_of_Optimized_app.pdb can be copied to the projects/setiathome.berkeley.edu folder, if available
-
My friend has installed the SSE2 client and it is crunching away
Thank goodness for that
-
Maybe someone can help ASAP..... The bench mark is lower with the OP'd client then it is without it...

I wouldn't worry about it, those boinc benchmarks are notoriously inaccurate and vary by version, price of the stock market and phase of the moon (j/k). They bear little if any relationships to the speed of processing. It would be far better to compare CPU times of same/close angle range tasks. Here I am sure you will find significant improvement.

So how do I find that out?? because my friend does seem to see any improvement
-
You need to examine the output of your tasks from your account page at the seti@home site. In particular the "CPU time" field, The "stderr out" box should say what application was in use for that workunit, and the "angle range". If no application name is mentiioned in the "stderr out" then it is probably running stock.
Different applications have different levels of information available, so comparison can sometimes be tricky, but :
Generally speaking, Give or take, a workunit with the same or very close angle range will crunch in about half to 3 quarters the time that it would take with the stock app ( Though this difference is not as big as it used to be, as not long ago many of the optimizations were ported to the stock app from here ....)
If you have trouble, post a link here to your SaH account page (don't worry others can't see private stuff,) make sure your machines are unhidden, and I could take a quick look at the tasks for you.

For those reading this thread, Some PMs were exchanged indicating the user (friend of russkris) wasn't comfortable allowing their computer(s) to be unhidden for diagnosis / assistance.
I have pointed out, as best I can, the difficulty that there is in providing the required assistance without being able to see the tasks, and also indicated that there is no personally identifiable information revealed by unhiding the machines.
Please anyone seeking assistance keep in mind when asking for help, that it is extremely difficult to recommend the correct course of action for something you cannot see.
ThankYou, Jason
-
Yeah.. sadly that seems to be the case, I have advise, there is nothing more we can do to make sure everything is working..
Thanks for all your time and help

Thanks Jason for your attempts to help the gents. :)
It's understandable to consider security concerns, especially when somewhat unfamiliar to this project and our forums, users, etc.
If they reconsider, they will find friendly folks here and on the main Seti board that will be glad to help & guide.
We're a friendly bunch after all. ;D
Who else would claim membership in a M. Python-inspired, alien-signal searching group?
Wait a minute......all of a sudden, that doesn't that sound so re-assuring.... :-\

I have no problems with it.. Dont really know what the prob is.. thats him.. I will let you know, if anything changes

Great! In the meantime, enjoy crunching and Welcome to the KWSN-Lunatics forum!!! Glad to have ya! ;D

Thanks mate....
Ni!

Just a few points to check locally, so yours can be sure the optimized application is really running:
1. on windows open the taskmanager's process list and look for the name of the application. That should be the same as the name of the application put into the projects/setiathome.berkeley.edu folder. Otherwise stock might still be running.
2. on all boinc versions open the slots/x folder (x = 0,1,...). There should be a link named same as the opt. application put into the projects/setiathome.berkeley.edu folder. If that link has still the name of the stock application stock is still used.
3. if sure that the correct optimized application is used, watch Boinc in advanced view while a computation error occurs. Right after the computation error has happened stop Boinc with File/Exit. Goto the slots/x folder that was used for crunching the erroneous work unit. Open the stderr.txt file with an editor (notepad, wordpad or similar). What error messages are listed there ?
-
he has the SSE2 version crunching with no errors. but he cant see any improvement...
maybe running the wrong version?
-
I guess the next question might be "What is he looking at and seeing no improvement?" ... The only really valid comparisons are same angle range tasks' cpu time, and it couldn't really have been crunching long enough to accumulate some of the same angle range, for comparison, as was run with the stock application could it ?
RAC ( Recent Average Credit ) takes about three weeks to rise & stabilise if that's what he's looking at ...
-
I dont really know to tell you the truth... Possible daily output, via the TN stats site
-
Yeah that would take a couple of days to show change, If it seems to be crunching without error I'd give it time. Sounds like it is doing the job ;)
-
Thats what I said... It's been a week
-
What about my mate run that benchmark program.. you know the one that runs and tells you what op'd file to use
. where do I find that?
-
I think you may be referring to the installer from the 2.2B package. That is outdated and there has been no such Installer made for 2.4 or 2.4V clients.
The current best correct means of selecting the application is to examine the CPU specifications using such as CPU-Z and choose the right one by name... Naturally there may be some problem with the machine, its configuration or the incorrect app may be in use. We have no way to establish if this is or isn't the case, and would be guessing.
