Opps wrong app_config is last post:

Good morning Chooka,

The file name is app_config.xml. If the file exists then right click the file and "Open With" notepad. If it is a new file then open notepad, insert the text and then from the file menu pull down select "Save As". Then go to the folder where M@W is located, my system is "F:\VolunteerComputing\BOINC\Data\projects\setiathome.berkeley.edu" and save the file as an XML file name "app_config.xml".

I'm running two work units at a time:

<app_config>
<app_version>
<app_name>setiathome_v8</app_name>
<plan_class>cuda50</plan_class>
<avg_ncpus>0.24</avg_ncpus>
<ngpus>0.50</ngpus>
</app_version>
<app_version>
<app_name>astropulse_v7</app_name>
<avg_ncpus>0.24</avg_ncpus>
<ngpus>0.50</ngpus>
</app_version>
<project_max_concurrent>20</project_max_concurrent>
</app_config>

Hope it works for you.

I was just thinking that maybe, just maybe that some of these posts would be better suited in another thread. Something like the crunching area. Would help others if they have a problem with a GPU card or want to talk about performance of their system. To me it isn't news about the new bundling of work units or new updates being released. Then others can read the title of the thread and see what people are talking about instead of wading through every thread to find something.

Thanks,

Rich

Hello Jake,

So far my 750Ti's are doing okay, thanks for all your hard work. Just got home so I'll fire up my 7970 GPUs and see how they do.

Hello,

There are a few problems with the new work units. Jake is looking at it but he also has been working long hours to optimize the systems. Give him a little time and he will resolve the problems.

Thanks

Hello everyone,

There are some anomalies with the new version that was released and Jake has been putting in some long hours. Please give him some time to address them. We are just going through some growing pains with the restarting of % done and the GPU work units being executed on the CPU instead of the GPU. I'm sure not much longer and he will have things ironed out.

Thanks Jake for all you effort and get some rest. We always perform better rested.

Thanks,

lol, I'll let the 12 WU's finish up with the CPU and then let more units start loading. I've done many mistakes in my time, fully understand. Keep up the good work.

Looks like the new version isn't using the GPU. My 750Ti show no GPU usage and the CPU task is being used fully. The first two WU's validated but used the CPU.

Here is from the standard error file if this will help:

Thank you Jake for the update.

I hope people will understand the problems your team face and the challenges that will be overcome. The funding will help. I appreciate what all of you are doing with the limited resources that you have. Keep up the good work and I also have to thank you for keeping us informed of the progress and goals. Don't forget to take some time for yourself, a person only lives once.
