My background is in writing C/C++ code for science codes to solve physics equations (fluid dynamics) on large clusters, e.g., 100K+ CPUs. I have used various parallel programming techniques, e.g., OpenMP for shared-memory, and MPI for synchronous and asynchronous distributed-memory parallelism. I have also done code performance optimization targeting memory-reduction and improving cache utilization, etc. and wrote a bunch of code for linear algebra, e.g., solution of large sparse linear systems, preconditioning for linear solvers, and worked with data structures for unstructured (arbitrarily-connected) grids/graphs involving, optimization for cache usage, etc.
