Writing parallel programs efficiently is still a problematic issue due to the lack of sophisticated tool support for the programmer. A new integrated tool environment will change this situation for the most popular programming environment for workstation clusters: for PVM. THE TOOL-SET for PVM will comprise a set of integrated tools which can either be used individually or in a combined mannergif. Tools will be subdivided into interactive tools for investigation and manipulation of the program state and automatic tools, which provide functionality that does not have to be controlled by the programmer. Both types of tools will use online data, trace data, and checkpoint information to perform their task. THE TOOL-SET will be composed of a debugger, a performance analyzer, a visualizer, a deterministic execution controller, a load balancer including a checkpoint generator, and a parallel file system. All tools will be available under the GNU General Public License Agreement. First versions for several of the tools will be released in fall 1995.
