Re: [eigen] (co-)mentoring for Google Summer of Code

unfortunately handling OpenCL is much more complicated as you have to generate and compile the code at runtime, and if the _expression_ is within a loop you would also like to cache the compiled code somehow. You would also have to deal with memory transfers while CUDA can do it for us.

Hi Gael,
  I wanted to add in, what about OpenCL support for expressions?
Or does that not make any sense from a performance POV?

Hi developers,

it's a shame that Eigen still haven't participated to GSOC. The deadline for organisations is within 2 weeks, and if I'm not alone willing to act as a mentor, I'll prepare the forms to apply.

So would any of you be interested to participate to GSOC 2015 as a mentor/co-mentor?

Here are some initial project ideas:

- blocking/tiling in ColPivHouseholderQR and other decompositions
- sparse eigen decomposition (followup of last spring student project)
- performance oriented unit-testing with a web interface to track perf regressions
- finalize sparse-block storage format and extend direct solvers to exploit it
- evaluate expressions through CUDA (based on Benoit Steiner's work on Tensors)
