The Workshop on “ Modern computer tools for the biosciences ” is a one-day event focussing on topics including the added-value of the Grid for Bioinformaticians, Biologists and Medical scientists, and the readiness of the Grid for these end-users The grid concept has already produced a variety of middlewares, components and platforms that are available around the World. But are facilites ready to be exploited by the true end-user? There are several challenging points that are still under development in the biosciences domain. The workshop will focus on some of these critical areas, notably, sharing biological data within distributed filesystems and database management systems, providing developers with programmatic usage of independant remote components such as web services or standard grid APIs, providing end-users with uniform grid access including ergonomic and efficient portals, and creating workflow on distributed resources, ...
