llvm dev - May 2021 - [GSoC] Integrating custom derivatives of numerical computing routines into Enzyme

Hi everyone,

I have been selected as a Google Summer of Code student this year to work
under the mentorship of William Moses, Johannes Doerfert and Vassil
Vassilev on integrating custom derivatives of popular numerical computing
routines like BLAS and Eigen into Enzyme.

As some of you might already know, Enzyme performs automatic
differentiation on LLVM IR and has uses in several algorithms like
backpropagation, Bayesian inference, etc.
My project this summer will mainly focus on allowing Enzyme to
automatically calculate the derivatives of commonly used functions that are
usually included from linked libraries without having the definitions of
these functions explicitly available in the generated LLVM IR, as well as
setting the groundwork for allowing easier integration of such functions
into Enzyme in the future.

The full GSoC proposal is here -

Looking forward to presenting some work that might be of interest to the
community in the near future :)

Cheers,
