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
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.
