A powerful Cray tool that gives detailed bar charts of a programs Mflop rate PAT A low overhead tool that can show parallel load balancing Benchlib The Cray Benchlib routines for T3E code optimisation. Dmget Large datasets may be required for program runs. Ideally, these need to be available on a file system local to the target machine. In this way the second file should already be retrived from tape before the first file has finished copying, thus greatly speeding up the process. File transfer File transfer and man cfsfiles for more details RCS Keep track of developments to source code and documentation efficiently without discarding earlier versions.
Collaborative development is supported through the locking of files and access control.
See man rcsintro for more details. It handles multiple developers, multiple directories and can operate over a network. GNU diffutils The Gnu diffutils version 2.7 are alternatives to those provided with Cray systems. They may have slightly different functionality so take care to note which you are using in scripts. This can be a particularly useful optimisation tool when the same source code is compiled on different architectures.
