/home/sharon/mfacto/mfakto-wrappertest/

has these files in it:

barrett15.cl barrett.cl boinc_finish_called common.cl COPYING datatypes.h gpusieve.cl job.xml mfakto.ini mfakto_Kernels.cl mfakto_Kernels.elf mfakto-x64 montgomery.cl mul24.cl README.txt results.txt stderr.txt tf_debug.h todo.txt worktodo.txt wrapper_26018_linux-u18_x86-64 wrapper_checkpoint.txt wrapperdir

What files? R we talking wrapper-test or BOINC world?

In terminal I ran:

sharon@sharon-ES7C95:~/mfakto/mfakto-wrappertest$ sudo ./wrapper_26018_linux-u18_x86-64

mfakto/mfakto-wrappertest folder has this in job.xml:

<job_desc> <task> <application>./mfakto-x64</application> <command_line>-d 0</command_line> </task> <unzip_input> <zipfilename>mfakto-linux64-v10.zip</zipfilename> </unzip_input> </job_desc>

<command_line>-d 0</command_line>

Yes.

It has one line in it:

no factor for M758604829 from 2^73 to 2^74 [mfakto 0.15pre8 cl_barrett15_74_gs_2]

IF I understand this last test was back to stand-alone w/o the wrapper and it now did not find the GPU. Whereas previously the GPU wasn't found only when we ran inside the wrapper. Is this correct?

Nope, try to download mfakto-linux64-v9.zip It contains the older mfakto file, replace it with yours. Also overwrite all .cl files.

1) I unzipped this downloaded zip creating a new test folder (mfakto-linux64-v9).
2) Replaced the mfakto-64 in this new folder with mfakto-64 from my 'wrapper=test' folder.
3) Replaced the .cl files in this new folder with wrapper-test's 7 .cl files.
5) Executed this --

ES7C95:~/mfakto/mfakto-linux64-v9$ ./mfakto-x64

6) Got the following but feel like I regressed...

mfakto 0.15pre8 (64-bit build)

Is this of any help?

but it is not working again.
This was before one of the many changes i should try.

The result.txt is old

no factor for M758604829 from 2^73 to 2^74 [mfakto 0.15pre8 cl_barrett32_76_gs_2]

[Try to set execute permissions also to wrapper file.

There is no file named "wrapper"
I have now set all files to exec.

There must be another format for specifying the GPU device??

Skip

The execute permission on mfakto file is missing but I have changed it. You also must copy the worktodo.txt into folder.

mfakto-x64 is executable and worktodo.txt was empty

I copied it again.
