  We study the impact of the jets and missing transverse momentum SUSY analyses
of the ATLAS experiment on the phenomenological MSSM (pMSSM). We investigate
sets of SUSY models with a flat and logarithmic prior in the SUSY mass scale
and a mass range up to 1 and 3 TeV, respectively. These models were found
previously in the study 'Supersymmetry without Prejudice'. Removing models with
long-lived SUSY particles, we show that 99% of 20000 randomly generated pMSSM
model points with a flat prior and 87% for a logarithmic prior are excluded by
the ATLAS results. For models with squarks and gluinos below 600 GeV all models
of the pMSSM grid are excluded. We identify SUSY spectra where the current
ATLAS search strategy is less sensitive and propose extensions to the inclusive
jets search channel.
