POSITION SUMMARY

The Scientific Computing Core (SCC) manages supercomputing resources and provides high performance computing (HPC) expertise to all centers at the Flatiron Institute, a division of the Simons Foundation, developing tools broadly useful to the scientific community as a whole.

The intern will work on a project at the intersection of astronomy and high-performance computing. The project will be selected based on the intern's skills and interests, but possible directions include:

• development of a Python software package with a compiled, parallelized backend to compute the two-point correlation function;
• adding MPI parallelization to the initial conditions generator for an exascale N-body simulation code;
• augmenting the build system, functionality, and parallel performance of several Python/C++ packages using the Flatiron Institute Non-Uniform Fourier Transform (FINUFFT).

The internship will take place in-person at the Simons Foundation’s offices in New York City from May 27, 2025 – August 8, 2025. Applicable travel assistance to New York City and a supported temporary housing option while in New York City may be available.
