SUMMARY:Towards Exascale Computing in Kinetic Simulations of Magnetic Fusi
 on Plasmas. Part II - Core and Edge
DESCRIPTION:Minisymposium\n\nMagnetic fusion plasmas are subject to a plet
 hora of collective effects such as electromagnetic waves and instabilities
 , spanning multiple time- and length- scales. The low collisionality of re
 actor core plasmas makes a kinetic description mandatory for an accurate r
 epresentation. Ions and electrons have very different dynamics, and theref
 ore the problem is intrinsically multi-scale, both in space and time. As w
 e go towards the plasma edge, collisionality increases and the relative fl
 uctuation amplitudes become close to unity. Core and edge plasmas present 
 very different physical conditions and, until now, these two regions were 
 typically treated separately. But given that these two regions actually st
 rongly interact with each other, the challenge to achieve realistic simula
 tions is to describe them in a unified framework. This Part II of the mini
 symposium will specifically address this issue. In particular,  pros and c
 ons of treating this problem using different numerical approaches will be 
 covered.\n\nChallenges and Recent Advancements in Eulerian Gyrokinetic Edg

 ..\n\nGyrokinetic theory is currently considered the best compromise to ta
 ckle and better understand turbulence-induced anomalous transport in magne
 tically confined plasmas. Despite its underlying sophisticated analytic op
 timizations, numerical simulations based on this 5D model remain challengi

 appan\n\nThe collisionality in tokamak plasmas is varying significantly ac
 ross the plasma radius. Indeed, the core of the plasma is in the low colli
 sionality regime and therefore requires a kinetic description. On the othe

 project aims at coupling core delta-f and edge total-f gyrokinetic si
 mulations for modeling the whole volume of the magnetic fusion reacto
