  We present new results from a series of LCDM simulations of cluster mass
halos resolved with high force and mass resolution. These results are compared
with recently published simulations from groups using various codes including
PKDGRAV, ART, TPM, GRAPE and GADGET. Careful resolution tests show that with 25
million particles within the high resolution region we can resolve to about
0.3% of the virial radius and that convergence in radius is proportional to the
mean interparticle separation. The density profiles of 26 high resolution
clusters obtained with the different codes and from different initial
conditions agree very well. The average logarithmic slope at one percent of the
virial radius is $\gamma = 1.26$ with a scatter of $\pm 0.17$. Over the entire
resolved regions the density profiles are well fitted by a smooth function that
asymptotes to a central cusp $\rho \propto r^{-\gamma}$, where we find
$\gamma=1.16\pm 0.14$ from the mean of the fits to our six highest resolution
clusters.
