Computational Methods for General Relativistic Magnetohydrodynamics are important means of studying compact astrophysical objects such as neutron stars and core-collapse supernovae, relevant e.g. to understand sources of gravitational radiation.Particular crucial elements of such methods including solving non-linear equations to extract the microphysical state from the conserved fluxes (endearingly called con2prim) or handling realistic equations of state (EOS) that are only given approximately in a tabulated manner. The state of the art for algorithms addressing these issue leaves to be desired, and significantly limits stability,accuracy, and performance of today's calculations.This workshop aims to review the known algorithmic and computational shortcomings, list requirements that an ideal solution should have,and discuss potential practical solutions.
