Getting the PPSieve WUs to run on ATI cards

[Maxwell]

Ok. Just figured this one out, so I'm posting a how-to for you folks with ATI cards on how to get this subproject to run (which will be helpful for the final PG challenge...). Before you attempt any of this, make sure you have closed BOINC (and this is intended for Windows systems):

1. MAKE SURE YOUR ATI DRIVER HAS OPENCL SUPPORT!!! I was consistently getting errors, and an LAF member on the PG boards pointed out to me that the driver I was using didn't have OpenCL support. Once I upgraded, everything was fine. I'm using driver 10.10, which has OpenCL support. 10.7 does not, 10.11 (oddly) does not. Before installing/upgrading drivers, make sure you have this support. [Note: MW, DNETC, and Collatz were not written in OpenCL, so they don't run into this problem.]
2. Download this executable file (it's safe) from the PG website and save it to your desktop.
3. Navigate to your BOINC Data Directory, projects folder, PG folder. Drop the executable from step 2 in there.
4. Open Notepad.
5. Paste this (thank you .Steve/Paladin/Poorboy for posting this) into Notepad and save it to the same folder as in Step 3 with the file name "app_info.xml":

<app_info>
<app>
<name>pps_sr2sieve</name>
<user_friendly_name>Proth Prime Search (Sieve)</user_friendly_name>
</app>
<file_info>
<name>primegrid_tpsieve_1.35_windows_intelx86__ati13ati.exe</name>
<executable/>
</file_info>
<app_version>
<app_name>pps_sr2sieve</app_name>
<version_num>135</version_num>
<plan_class>ati13ati</plan_class>
<avg_ncpus>0.05</avg_ncpus>
<max_ncpus>1</max_ncpus>
<flops>1.0e11</flops>
<coproc>
<type>ATI</type>
<count>1</count>
</coproc>
<cmdline></cmdline>
<file_ref>
<file_name>primegrid_tpsieve_1.35_windows_intelx86__ati13ati.exe</file_name>
<main_program/>
</file_ref>
</app_version>
</app_info>

6. Make sure your PG preferences allow ATI WUs to be downloaded.
7. Restart BOINC.

Should work...

A couple have validated now...

1800 credits each. ~1800s on the 5970 at 725MHz, ~1300s at 850MHz.

Thank you Maxwell for the info.

Now just need work as PG's server tells me.....
11/24/2010 4:10:25 AM PrimeGrid Requesting new tasks for GPU
11/24/2010 4:10:50 AM PrimeGrid Scheduler request completed: got 0 new tasks
11/24/2010 4:10:50 AM PrimeGrid Message from server: No work sent

Ok. Got this to work also.

After doing the above steps, I instantly got 21 GPU tasks.

So I am back on my fav. project...PG....

I haven't had trouble getting work since I got the ATI app... BOINC is reading the app_info file, yes? And you have ATI work selected on the PG site, right? (Forehead-smack questions first... )

Whoops! Redundant post. Nothing to see here. Move along.

These aren't the droids your looking for.........

Question: Has anyone tried running two wu's concurrently like you can with MW?

Question: Has anyone tried running two wu's concurrently like you can with MW?

I haven't, but people have. It's not too useful because the WUs are much longer. If you're interested, change "count" to .5 in the app_info file above...

Yeah, I did that about ten minutes after I posted the question. so far no "crash n' burn" I did notice that one wu crunches slower than the other but any increase in production is good!
BTW: My two nVidia cards cranked out more credits than the rest of my mini farm combined. Yes, yes, I know. Apples n' Oranges......
