I came back to this problem again.
Searched through the source code and found the exact ssh command which
executes to run sage code:
command = 'sage-native-execute ssh -t %s "ulimit %s; %s"'%(server,
ulimit, command)
# from expect.py
sage-native-execute script looks like this:
#!/bin/sh
LD_LIBRARY_PATH=$SAGE_ORIG_LD_LIBRARY_PATH; export LD_LIBRARY_PATH
if [ `uname` = 'Darwin' ]; then
DYLD_LIBRARY_PATH=$SAGE_ORIG_DYLD_LIBRARY_PATH
fi
"$@"
As I understand the problem in environment settings which are transfered
to pool account, is that correct ?
