I have extended the parameter list for mfakto. (and compiled)


Are you sure that you have taken into account all possible combinations of these parameters?
- numbering platform / device (from one) and just a device (from zero).
- "ingenious" user config and trivial "-device 0" from wrapper
- or a simple conflict in the numbers of these parameters

a couple of examples for a logic test
( -d 11 --device 0)
( -d g --device 0)
( -d c --device 0)


can simply ignore (delete when analyzing arguments) the --device parameter in the presence of the -d parameter?

option -d don't work with 0, start from 1

-d 00-10
Select device - Error: No platform found
ERROR: init_CL(3, 10) failed


-d 11
Select device - Get device info - Compiling kernels.

no, app_config is better

wrapper receives this argument (--device N) and passes it to the application (job.xml <append_cmdline_args/>)

the question is in the source of this argument - a task template on the server ($GPU_DEVICE_NUM), a sheduler, or a local client?
find and neutralize :o)

or
- change wrapper - force it to translate into a form that the application understands.
- change application - add this form of argument
- switch to another platform/device selection scheme - for example opencl_platform.txt

mfakto has option "-d c" - force using all CPUs
mfaktc does not have such an option,
so my tip is past the target :(

<app_config>
<app_version>
<app_name>GPU72</app_name>
<plan_class>cuda100</plan_class> # 1
<cmdline>-d c</cmdline> # 2 - try multi-GPU, 2 tasks * 2 GPU
</app_version>
</app_config>

there is no <cmdline> either in the app_version section or in workunit
so that it can be added to the app_config file without any problems

<app_version>
<app_name>GPU72</app_name>
<plan_class>opencl_ati_101</plan_class>
<cmdline> -d 1 </cmdline>
</app_version>

that's just different tasks need different parameters, as an option to launch the second instance of BOINC for the second GPU with the option "-d 1" in this project

PS in this way I was able to run some tasks on Intel GPU although the server did not recognize this GPU
