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.
