Hi all,
We have been encountering strange errors recently: A rather large number of our
tasks fail because the command line arguments are incorrect. We traced one
specific failed task and were lead to the bin/create_work program. Here is the
trace:
1) These commands are used to submit work to BOINC's DB:
ln -s `pwd`/ibadfp_p1/instance.txt `bin/dir_hier_path
instance.txt_31jan11_am_16_030_200_000_1_235`
ln -s `pwd`/ibadfp_p1/ipfile.bin `bin/dir_hier_path
instance.txt_31jan11_am_16_030_200_000_1_235.ip`
ln -s `pwd`/ibadfp_p1/qubit.param `bin/dir_hier_path
instance.txt_31jan11_am_16_030_200_000_1_235.param`
bin/create_work -appname fokker_planck -wu_name 31jan11_am_16_030_200_000_1_235

2) These are the contents of the file

Please note the command line argument "--input_file"
3) This is what we see in the database:
<workunit>
<file_ref>
<file_name>instance.txt_31jan11_am_16_030_200_000_1_235</file_name>
<open_name>instance.txt_31jan11_am_16_030_200_000_1_235</open_name>
<copy_file/>
</file_ref>
<file_ref>
<file_name>instance.txt_31jan11_am_16_030_200_000_1_235.ip</file_name>
<file_name>instance.txt_31jan11_am_16_030_200_000_1_235.ip</file_name>
<open_name>ipfile.bin</open_name>
<copy_file/>
</file_ref>
<file_ref>
<file_name>instance.txt_31jan11_am_16_030_200_000_1_235.param</file_name>
<file_name>instance.txt_31jan11_am_16_030_200_000_1_235.param</file_name>
<open_name>qubit.param</open_name>
<copy_file/>
</file_ref>
<command_line>
--T 0.03 --t_f 0.0002 --n_particles_per 2 --h_ramp_mid 0.000 --h_ramp_width
0.0025 --time_step_factor 48.0 --gamma_frac 1.0 --t_fraci 0.38 --t_fracf 0.88
--input_file instance.txt_31jan11_am_16_030_200_00_11_235
</command_line>
</workunit>
Please note how the last few characters corresponding to the "--input-file"
parameter have changed from "200_000_1_235" to "200_00_11_235"
The result is a failure on a volunteer computer, with the app complaining that
it can't open the input file.
How could this happen? Any help in resolving this issue is appreciated.
