[Advcomparch] Πρόβλημα(?) στo create_parsec_workspace

[ ]

Όταν εκτελώ την εντολή ~/advcomparch-2015-16-ex1-helpcode/cslab_create_parsec_workspace.sh, πέραν των άλλων, μου πετάει τα εξής errors:
cp: cannot stat ‘pkgs/apps/swaptions/inputs/input_simlarge.tar’: No such file or directorytar: swaptions-input_simlarge.tar: Cannot open: No such file or directorytar: Error is not recoverable: exiting nowrm: cannot remove ‘./parsec_workspace/inputs/swaptions-input_simlarge.tar’: No such file or directory 

cp: cannot stat ‘pkgs/kernels/streamcluster/inputs/input_simlarge.tar’: No such file or directorytar: streamcluster-input_simlarge.tar: Cannot open: No such file or directorytar: Error is not recoverable: exiting nowrm: cannot remove ‘./parsec_workspace/inputs/streamcluster-input_simlarge.tar’: No such file or directoryln: failed to create symbolic link ‘./parsec_workspace/Face_Data’: File exists
Είναι κάτι στο οποίο πρέπει να δώσω σημασία; Και αν ναι, τότε τι μπορέι να έχω κάνει λάθος;
