Summary:New release of pkdgrav2 (non Fortran version)
Project:pkdgrav2: a parallel n-body gravity code

This latest release uses single precision multipole code which achieves the same errors down to at least theta=0.3. Note however, that at the same theta the code is much more accurate than previously. To get similar force errors as in older pkdgrav2m versions you can add about 0.2 to the theta you set for this version. Eg. theta=0.5 now has errors comparable to theta=0.3 in original pkdgrav2. The single precision currently only saves memory in the tree, but will speed up the code in the *next* release. This release also avoids the use of a Fortran compiler, which makes porting much easier. - Joachim
