New parallel library allows maximum performance for communication networks
A new message-passing library that makes it possible to extract optimum performance from both workstation and personal computer clusters, as well as from large massively parallel supercomputers has been developed by researchers at the U.S. Department of Energy’s Ames Laboratory. The new library, called MP_Lite, supports and enhances the basic capabilities that most software programs require to communicate between computers.
Although MP_Lite could be scaled up easily, its objective is not to provide all the capabilities of the full message-passing interface, or MPI, standard. MPI is a widely used model that standardizes the syntax and functionality for message-passing programs, allowing a uniform interface from the application to the underlying communication network. Parallel libraries that offer the full MPI standard ease programming problems by reducing the need to repeat work, such as defining consistent data structures, data layouts and methods that implement key algorithms.

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
