Benchmark Dataset Cloning issue

[hwiiiii]

Hi.

I want to ask you about the git repository access issue.
I tried to run benchmark test of PageRank, so I typed

./benchmark.sh pagerank

but it turned back an error, that ...

cloning oprecomp-data repository
Initialized empty Git repository in my..directory../micro-benchmarks/mb/data/source/.git/
git@iis-git.ee.ethz.ch's password: 
Connection closed by 129.132.2.24
fatal: The remote end hung up unexpectedly
failed to update data

I failed because it requested me the password of ethz git.

Is it possible to access on benchmark datasets and clone them from 'oprecomp-data' repo without your permission?
Should I have request you to get the authority of git repository first?
Please let me know the solution of this problem.

Thanks.
