I'll try some different scenarios when I have time here between patients and report back.
I just checked MW's app page and the ATI app is still listed as ATI14 which uses Stream code. Take a look at the MW wu's, are they tagged as ATI14?
When I first started crunching MW 2+ years ago, one could run two wu's simultaneously but that was using CCC 10.10. When ATI/AMD started adding openCL to the driver's it fubared the ability to do this, at least for my 4850s. You may wish to try an app_info file like this one (if ATI14)
Code:
<app_info>
<app>
<name>milkyway</name>
</app>
<file_info>
<name>milkyway_separation_0.82_windows_x86_64__ati14.exe</name>
<executable/>
</file_info>
<app_version>
<app_name>milkyway</app_name>
<version_num>82</version_num>
<flops>1.0e11</flops>
<avg_ncpus>0.05</avg_ncpus>
<max_ncpus>1</max_ncpus>
<plan_class>ati14ati</plan_class>
<coproc>
<type>ATI</type>
<count>0.5</count>
</coproc>
<cmdline></cmdline>
<file_ref>
<file_name>milkyway_separation_0.82_windows_x86_64__ati14.exe</file_name>
<main_program/>
</file_ref>
</app_version>
</app_info>
You might also have to change the exe reference in the config if it doesn't match the app in the project folder.
You can also try the opti_apps written by Arkayn and Crunch3r (Link) although MW tends to roll the latest opti_app into the server for client DL'ing.
Hope this helps.
