The best of both worlds

comparison between NumPy, Cython and Cython with the OpenCL solver

Sometimes, rejecting unfeasible ideas early enough is a crucial step towards actually solving a problem. In my quest to speed up the ocean modeling framework Veros, I considered the option of restructuring the existing pure Python code in order to

Full speed ahead – Accelerating ocean simulations

Coastal wave propagation Atlantic veros ocean simulation

How will Earth’s climate change in the next century? This is the kind of questions climate researchers ask themselves and the reason they develop global climate models. These are used to simulate conditions over long periods of time and under

Cluster Scale GPGPU with OpenCL

Previous posts about climate modeling and CESM were required as this post is the crème de la crème of CESM from my point of view. Cluster scale GPGPU seems to be very nice, on paper, but as soon as we

When FORTRAN met OpenCL – A Love Story? (of Integration)

Both of the projects Lukas and I are working on, here at NBI Copenhagen, are based on FORTRAN. Either Photon-Plasma simulations or CESM for climate modeling (as most climate modeling software around). Certainly, a vast majority of scientific code is
