MPE graphics -- Scalable X11 graphics in MPI
- Argonne National Lab., IL (United States). Mathematics and Computer Science Div.
As parallel programs enter the mainstream, they need to provide the same facilities and ease-of-use features expected of uniprocessor programs. For many applications, this means that they need to provide graphical output. This talk discusses a library of routines that provide scalable X Window System graphics. These routines make use of the MPI message-passing standard to provide a safe and reliable system that can be easily used in parallel programs. At the same time they encapsulate commonly-used services to provide a convenient interface to X graphics facilities. The easiest way to provide X11 graphics to a parallel program is to allow each process to draw on the same X11 Window. That is, each process opens a connection to the X11 server and draws directly to it. In one sense, this is as scalable a system as possible, since the single graphics display is an unavoidable point of sequential access. However, in reality, an X server can only accept a relatively small number of connections. In addition, the latency associated with each transmission between a parallel process and the X Window server is relatively high. This talk addresses these issues.
