SBIR Phase I: Advanced Scientific Parallel Debugger

*9661722 Giancola本小型企业创新研究第一阶段面向使用高性能并行计算机的开发人员。因此，这些计算机的主要商业应用代码是软件开发的工具。到目前为止，这些工具的设计并没有着眼于高性能计算用户的需求，而是从它们的目标在规模上更有限的工作站移植而来的。这些工具中最重要的，也是迄今为止最不足的，就是符号调试器。在CTSS和UNICOS的超级计算机开发环境中的经验表明，有效的调试器除了具有过程控制和变量评估的标准功能外，最基本的功能是能够保存目标的状态以供以后恢复。宏处理是另一个必需的功能；它允许用户记录复杂的调试命令序列，以便于重复使用。同样重要的是接受不完整的符号表信息集，以在优化代码上实现最大可能的功能。该项目将为调试器开发软件技术，相信高性能并行计算环境中不存在这样的调试器。这项技术将销售给一个或多个并行计算机硬件供应商，以纳入专有调试器，与系统捆绑和非捆绑销售，并保留销售工作站版本的权利。***

*** 9661722 Giancola This Small Business Innovation Research Phase I is directed at developers working with high performance parallel computers. The primary commercial application codes for these computers are thus tools for software development. To date, these tools have not been designed with an eye to the requirements of the high performance computing user, but rather have been ported from workstations, where their targets are much more limited in scale. The most important of these tools, and to date the most inadequate, are the symbolic debuggers. Experience in the supercomputer development environment on both CTSS and UNICOS has shown that the most essential feature for an effective debugger to have in addition to the standard ones of process control and variable evaluation is the ability to save the target's state for later restoration. Macro processing is another required capability; it allows the user to record complex sequences of debugging commands for easy reuse. Also essential is acceptance of an incomplete set of symbol table information to enable the maximum possible function on optimized code. This project will develop software technology for debuggers which it is believed no such debugger for high performance parallel computing environment exists. This technology will be marketed to one or more parallel computer hardware vendors for incorporation into proprietary debuggers for bundled and unbundled sale with systems and to retain the rights to market a workstation version. ***
