The ascube and asflat posterior transformations are currently not gpu friendly. These transformations could potentially be made gpu friendly and non allocating. Here's a series of helpful places to look:
TransformationVariables.jl
TransformationVariables is the underlying dependency used to handle the posterior transformations.
ComponentVectors.jl
The current representation of the data is in terms of named tuples. Representations in terms of componentvectors are likely to be more GPU friendly
