# CSERD: Computational Science Education Reference Desk

The Computational Science Education Reference Desk (CSERD) features resources to help students learn about computational science and to help teachers incorporate it into the classroom. Computational science involves the appropriate use of a computational architecture or computing environment (a computer, calculator, abacus, dice, or the like) to apply some algorithm, or mathematical method, to solve some scientific application, or problem. This combination of application, algorithm, and architecture results in a model that can be used as a scientific tool. The Resources section of the CSERD site provides a permanent collection of materials developed especially for CSERD, including models (pieces of scientific software), activities (lessons or lesson plans that use models), tutorials (short courses designed to teach a specific topic), applications, algorithms, architectures, and several other categories. The Resources form part of a larger catalogue of computational science items gathered by CSERD from around the internet. The catalogue can be searched or browsed by subject, keyword, education level, audience, and resource type. The record for each item includes a link to the resource, title, brief description, education level, and other information.

This tool allows the user to visualize functions of three variables as diffuse clouds. The "cloud" can be rotated and viewed from different angles. Also, slices of the x=0, y=0, and z=0 plans can be viewed. Plots can be viewed with different colormaps, including red-blue maps to indicate the sign of the function.

CitcomS, a finite element code that models convection in the Earth's mantle, is used by many computational geophysicists to study the Earth's interior. In order to allow faster experiments and greater simulation capability, there is a push to increase the performance of the code to allow more computations to complete in the same amount of time. To accomplish this we leverage the massively parallel capabilities of graphics processors (GPUs), specifically those using NVIDIA's CUDA framework. We translated existing functions to run in parallel on the GPU, starting with the functions where the most computing time is spent. Running on NVIDIA Tesla GPUs, initial results show an average speedup of 1.8 that stays constant with increasing problem sizes and scales with increasing numbers of MPI processes. As more of the CitcomS code is successfully translated to CUDA, and as newer general purpose GPU frameworks like Fermi are released, we should continue to see further speedups in the future.
