But I see you're using 0.5GPU so you've to use atleast 1 cmd_line setting,
1 instance_per_device, IIRC.......

And I wouldn't stick to defaults, depending of the GPU you're using.
Use an unroll factor smaller as the # of CU's in your GPU, not the default 2,
but 10 to # of CU's.
Ffa_block can also be larger then 4096, double it and use ffa_block_fetch 4096,
for a start.
Or you can do 1 instance per device.

an instances_per_device parameter is no longer required, from the release notes:

-instances_per_device param still supported but not required for using multiple instances of app.
One should set <count> tag in app_info to get multiple instances running.

Paul the following works fine for my GTX 470

<app>

</app>
<file_info>
<name>AP6_win_x86_SSE2_OpenCL_NV_r1316.exe</name>

<max_ncpus>0.2</max_ncpus>
<platform>windows_intelx86</platform>

<file_ref>
<file_name>AP6_win_x86_SSE2_OpenCL_NV_r1316.exe</file_name>

</file_ref>
</app_version>

Make sure <name>AP6_win_x86_SSE2_OpenCL_NV_r1316.exe</name> & <file_name>AP6_win_x86_SSE2_OpenCL_NV_r1316.exe</file_name> lines are the same as the files in your setiathome.berkeley.edu folder
