With the aim to help people to run GEOtop and understand a little more its code, and having a preview of what its port to C++ means, I and Mountain-eering organized a three days workshop with a few people interested. This is possible a seed for workshops for a larger audience.
The speaker was Matteo Dall'Amico, a former Ph.D. student of mine, and at present one of the owners of Mountain-eering.
older post for the theory and some is also contained in the GEOtop History- Part I and Part II).
The slides of the three days can be found here. However, they do not contain the full information, and should be used as an index of the thing to look for becoming really GEOtop proficient.
