       Hi,

I cannot reproduce what you get:

zimmerma@coriandre:~/svn/cado-nfs$ ./cado-nfs.py 
100000000000000000000000000000000000000001087 -dlp -ell 
5343950341598815341459838431296083 -gfpext 2
...
RuntimeError: no parameter file found for p2dd45 (tried p2dd45)
Feel free to submit one!

Best regards,
Paul Zimmermann
