Title: Computation errors
Post by: jave808 on January 15, 2016, 01:19:13 AM
Hi,

I've decided to give this project a go.  I know it's not crunching "pure" science, but I would like to generate some bitcoin to help out the BOINCStats campaign (http://www.bitcoinutopia.com/2015/10/boincstats-hardware/#.Vper8tBWhoN).

I received an invitation code from Henri (which happens to be the same code that Dingo posted in another thread) and created a new account.  I then added the project to BOINC Manager and WU's started to download.  Everything was going fine until I quickly realised the tasks weren't completing properly - all gave "Computation errors".  My Norton AV software also flagged "minerd.exe" and "cudaminer.exe" as trojans.  After some Googling around I found out that these apps were often flagged as viruses and in order for the tasks to complete successfully, one needed to make exceptions for these apps in the AV program.

So I think I've done this correctly, but I'm still getting "Computation errors" for the Cudaminer tasks.  Anyone out there with experience in setting up Norton Internet Security 2015 to allow for proper operation of these two apps?

Jave.

Not sure but the error says it's out of memory ?  Are you just running one task at a time ??

Thanks for you feedback Dingo.  I am only running one task at a time.  Where did you get that error info from?  "Event log" in BOINC Manager doesn't give that much info.

From your list of tasks at the site. Such as this one.

http://www.bitcoinutopia.net/bitcoinutopia/result.php?resultid=111397387 (http://www.bitcoinutopia.net/bitcoinutopia/result.php?resultid=111397387)

If you don't have it already you may need the updated.   "Visual C++ Redistributable for Visual Studio 2012 Update 4" (both x32 & x64).  It looks like a VS error.

PS That Quadro card has 512mb memory I wonder how much each WU use's?  It's just that first part of the error mentions "out of memory".  Just a thought?

Many thanks JugNut - I have found where task details live now. :-)

I installed the updated Visual C++ files (both 32 and 64-bit) as suggested.  Alas, I am still getting computational  errors.

I think I've found the solution. I've added a app_config.xml file to the relevant projects directory.  See code below.
<app_config>
<app_version>
<app_name>cudaminer_14</app_name>
<plan_class>cuda</plan_class>
<cmdline>-l F44x1</cmdline>
</app_version>
<app_version>
<app_name>cudaminer_13</app_name>
<plan_class>cuda</plan_class>
<cmdline>-l F44x1</cmdline>
</app_version>
<app_version>
<app_name>cudaminer_6</app_name>
<plan_class>cuda</plan_class>
<cmdline>-l F44x1</cmdline>
</app_version>
<app_version>
<app_name>cudaminer_7</app_name>
<plan_class>cuda</plan_class>
<cmdline>-l F44x1</cmdline>
</app_version>
<app_version>
<app_name>cudaminer_3</app_name>
<plan_class>cuda</plan_class>
<cmdline>-l F44x1</cmdline>
</app_version>
</app_config>


They key to success is the "<cmdline>-l F44x1</cmdline>" modifier.  I set up cudaminer as a standalone app using this guide (http://www.minedogecoin.com/getting-started-with-nvidia-gpu-mining-dogecoins-using-cudaminer/).  I then joined a pool and went to this guide (https://www.reddit.com/r/dogecoin/comments/1tghi3/guide_nvidia_cudaminer_quickstart_guide/) for further instructions also.  Once you run cudaminer with the auto-tuning switch ("-l auto") you can then add the configuration suggested in the app_config.xml file and it should work. :-)

That's an excellent find there Jave. I did a fare amount of googling on that subject didn't find anything like those nuggets of gold. That may come in very handy to many other people as well  :thumbsup:

I'm glad you got it sorted mate. +1

Crunch-on  :crazy

Great detective work there to find all that info.  +1 for your effort and sharing.

When I saw heaps of errors I quit the project.  :thumbdown:
