Hi Stephen,

I've been comparing results of the halo mass function with the old ones on the small dataset, it seems the new fit function is systematically higher than the old ones.  I've also ran it on a 20 Mpc 800 cube unigrid, and the fit is also higher than the simulated data by almost 4x.  I'll send the pictures in another private email so I don't spam the list.  

Just want to let people know it no longer hangs due to not enough memory during calculation of the HMF.  Does anyone have a halo profile data at hand they can just check the halo mass function against the Warren fit in particular?  Calculating the halo mass function is quick if the haloes are already profiled and saved, took less than a minute on a single processor for the 800 cube.

G.S.

I see the same issue as you. I turned down the precision of the
integrator in the halo mass function which should make these kind of
memory overruns less likely. Please update your install and let me
know if A) you still see problems or B) if the fit looks fishy (due to
the lowering of the integrator's precision).

Good luck!
