Dear Support,
I have a peculiar problem running some program remotely on the gpsc7.
My account name is "bat002". The working directory in question is
/home/bat002/NERACOOS/waves/work/
The Details leading to the problem are itemized below in (A) to (D):
(A) I have a crontab job running on my workstation, that runs twice a day, see the
line below:
50 02,14 * * *
/home/btoulany/NERACOOS/winds/work/get_proc_NAVGEM_COAMPS_winds_NERACOOS_gpsc71.sh >
/dev/null 2>&1
(B) The script get_proc_NAVGEM_COAMPS_winds_NERACOOS_gpsc71.sh does two things:
1) Gets the needed input fields (wind & ice) to drive the wave model.
2) It launches another script touch_gpsc71_waves_NERACOOS_with_ice.sh
(C) The second script touch_gpsc71_waves_NERACOOS_with_ice.sh does four things:
1) scp -p $path_d/flag_time
bat002@inter-dfo-ubuntu2204.science.gc.ca:/home/bat002/NERACOOS/waves/data/<mailto:bat002@inter-dfo-ubuntu2204.science.gc.ca:/home/bat002/NERACOOS/waves/data/>
2) scp -p $wn_proc/grd?.${ID}.wnd.nc
bat002@inter-dfo-ubuntu2204.science.gc.ca:/home/bat002/NERACOOS/winds/processed/<mailto:bat002@inter-dfo-ubuntu2204.science.gc.ca:/home/bat002/NERACOOS/winds/processed/>
3) scp -p $ice_proc/grd?_${ID}.ice
bat002@inter-dfo-ubuntu2204.science.gc.ca:/home/bat002/NERACOOS/ices/processed/<mailto:bat002@inter-dfo-ubuntu2204.science.gc.ca:/home/bat002/NERACOOS/ices/processed/>
4) launches remotely a new script process_waves_NERACOOS_with_ice.sh on gpsc7
ssh bat002(a)inter-dfo-ubuntu2204.science.gc.ca
/home/bat002/NERACOOS/waves/work/process_waves_NERACOOS_with_ice.sh
(D) This new script process_waves_NERACOOS_with_ice.sh running on gpsc7 does few
things:
1) Processes the winds using ww3 executable "ww3_prnc" (prepares
the input wind fields in NetCDF format 'nc')
2) Processes the ices using ww3 executable "ww3_prep" (prepares
the input ice fields in text format)
3) Launches the main ww3 program, using ww3 executable "ww3_multi"
4) ...
Note1: process_waves_NERACOOS_with_ice.sh runs fine on gpsc7 when I run it interactively
(i.e. when I am logged on to gpsc7).
But, when I launch it remotely (as described above in 4)), it would fail running
"ww3_prnc" with this error below:
/home/bat002/ww3-v516/exe_shrd_IC0_IS0_REF0_DIA_v516-gpsc72-r8-22-U22-SP2-2/ww3_prnc:
symbol lookup error:
/home/bat002/ww3-v516/exe_shrd_IC0_IS0_REF0_DIA_v516-gpsc72-r8-22-U22-SP2-2/ww3_prnc:
undefined symbol: netcdf_mp_nf90_open_
But, if I login onto gpsc7 and fire the same module "ww3_prnc" it works fine.
Note2: 'Remotely' after failing to run module "ww3_prnc" it proceeds
on running "ww3_prep" successfully,
But then "ww3_multi" would fail automatically as the winds are
missing.
The best explanation I could find is "compile-time error with mis-matched
versions..."
I recompiled the codes with the new site profile 20250530/20252026 (everything else in my
.profile remained the same).
The executables didn't change a bit (identical) and the problem remains
Do you have any suggestion to help solve this peculiar problem?
Many thanks
