  The NNPDF collaboration has recently presented NNPDF3.1, a new determination
of the parton distribution functions (PDFs) of the proton including a number of
new data, some of which are particularly sensitive to the gluon PDF at large x.
In this contribution, we present the results of two new analyses based on
NNPDF3.1. First, we study the impact of the ATLAS 2011 7 TeV inclusive jet data
on the gluon PDF including different rapidity bins. Second, we quantitatively
compare the constraints provided by all measurements sensitive to the large-x
gluon PDF, namely inclusive jet cross sections, the transverse momentum
distributions of the Z-boson and top-pair rapidity distributions.
