A method is.pres.nted for retrieving the magnetos.heric ion dis.ribution from En-ergetic Neutral Atom (ENA) meas.rements.made by the NUADU ins.rument on the TC-2 s.acecraft. Bas.d on the already well-es.ablis.ed method of cons.rained lin-ear invers.on, an iterance technique s.itable for the low count ENA meas.rements.has.been developed which is.tolerant of the nois. background. By the iterance technique, it is.pos.ible for the firs. time to s.multaneous.y retrieve the magneto-s.heric ion dis.ribution and the exos.heric neutral dens.ty, and further to recover global ENA emis.ions.in three dimens.ons. The technique is.applied to a repre-s.ntative ENA image recorded in energy channel 2 (protons. 50―81 keV) of the NUADU ins.rument during a maj.r geomagnetic s.orm and it is. thereby, s.own that the retrieval method developed provides.a us.ful tool for extracting ion dis.ribution information from ENA data.

We dis.us. the performance characteris.ics.of us.ng the modification of the tree code s.gges.ed by Barnes.in the context of the TreePM code. The optimization involves.identifying groups.of particles.and us.ng only one tree walk to compute the force for all the particles.in the group. This.modification has.been in us. in our implementation of the TreePM code for s.me time, and has.als. been us.d by others.in codes.that make us. of tree s.ructures. We pres.nt the firs. detailed s.udy of the performance characteris.ics.of this.optimization. We s.ow that the modification, if tuned properly, can s.eed up the TreePM code by a s.gnificant amount. We als. combine this.modification with the us. of individual time s.eps.and indicate how to combine thes. two s.hemes.in an optimal fas.ion. We find that the combination is.at leas. a factor of two fas.er than the modified TreePM without individual time s.eps. Overall performance is.often fas.er by a larger factor becaus. the s.heme for the groups.optimizes.the us. of cache for large s.mulations.
