Re: [Condor-users] Library access problem

["Junaid N. Sahibzada" <sjunaidn@xxxxxxxxx>]

Erik,
  
  I am still getting the error
  
  condor_exec.exe: error while loading shared libraries: libITKIO.so: cannot open shared object file: No such file or directory
  
  Here is my submit file
  
  universe = vanilla
  executable = ../milxMatrixInversion
  log       =  matrix.log
  error    =   matrix.error
  output   =   matrix.output
  enivornment =  LD_LIBRARY_PATH=/usr/lib:/nfs/mid/projects/Registration/vtkCISG/lib:/nfs/mid/projects/Registration/vtkCISG/tcl/vtkview/include:/usr/local/lib/vtk:/nfs/mid/projects/Registration/vtkCISG/lib:/nfs/mid/homes/sah006/bhautik
  arguments = case2-aflr p 1 4
  queue
  
  
  We have a shared NFS file system so no matter where the job runs all paths starting with nfs are accessible to all of the nodes.
  
  the library i am searching for is in /nfs/mid/homes/sah006/bhautik
  
  Any clues !
 why this
 is happening?

Are you really sure you want to be inverting a matrix? I admit to knowing
absolutely nothing about what your science is, and I admit to not doing
that well in numerical linear algebra, but I do remember that
inverting a matrix to solve a system of equations is usually not the best
way to do it. But if you're happy with inverting then I'm happy with you
inverting.

put
enivornment = LD_LIBRARY_PATH=/path/to/your/home/directory

in your submit file

Or, put your job in a wrapper script that sets LD_LIBRARY_PATH before
starting up.

Or, if your home directory is different on each machine, you may need
some help from your condor administrator to put something in the machine
ad so you can use the $$ method of taking attributes out of the machine
ad and putting them into the environment of the machine. You may want to
do this if you want to use different shared libraries based on what
machine you're on (maybe you want AMD-optimized libraries on one machine,
and P4 optimized libraries on another)

Or, statically link.
