SUMMARY:The PORTALS Workflow: Accelerating Core Transport Predictions with
  Surrogate-Based Optimization Methods
DESCRIPTION:P. Rodriguez-Fernandez and N.T. Howard (MIT Plasma Science and
  Fusion Center) and J. Candy (General Atomics)\n\nPredicting core performa
 nce in magnetic confinement fusion devices requires accurately modeling th
 e balance between heating sources and transport mechanisms. However, the n
 onlinear electromagnetic turbulence in tokamak and stellarator plasmas mak
 es such modeling computationally demanding, as capturing all relevant scal
 es necessitates the use of expensive nonlinear gyrokinetic simulations—cur
 rently the gold standard, as implemented in codes such as CGYRO [1]. This 
 talk presents the application of surrogate-based optimization (SBO) method
 s for efficient integration with nonlinear gyrokinetic codes to perform pr
 edictive transport modeling. The PORTALS workflow [2,3], which combines SB
 O techniques with physics guidance, has enabled the highest-fidelity predi
 ctions of burning plasma core performance to date. The use of PORTALS, alo
 ng with advances in high-performance computing acceleration of gyrokinetic
  simulations, marks the beginning of a new era in core transport research—
 one in which high-fidelity physics models can directly inform the design o
 f next-generation fusion devices.\n\n[1]  J. Candy et al Journal of Comput
