Was Life on Earth Spawned on the Ocean Floor?

Researchers studying whether life on Earth could have begun on the seafloor said hot vents at the bottom of the ocean could have produced the organic molecules that are necessary for life. The study by University College London (UCL) chemists, published recently in the journal Chemical Communications, shows how the …

OpenMP vs. MPI: Which Is Better?

Unlike SIMD, where vectorization has multiple data items affected by a single instruction, in SPMD (Single Program Multiple Data) multiple processors run the same program but operate on different subsets of the data. There are two different ways that you can implement SPMD which depend upon the underlying architecture. If …
