XMTV - A Graphics Server for LAM

XMTV is an X/Motif based graphics client/server package that emulates a frame buffer. It is implemented on top of LAM, a cluster computing environment for UNIX. It provides an easy to use, low cost alternative for run-time visualization of computation results.

The XMTV client library can be used by MPI applications under LAM, from C and Fortran. It provides a simple interface to plot coloured data frames. The XMTV server can be run on any node in the LAM multicomputer. The graphics calls locate and direct their requests to the proper destination.

XMTV 1.0 will not compile with LAM 6.0. Watch for XMTV 1.1 to be released soon.
