udb - KSR Parallel Program Debugger <author> <version> <abstract> Udb (Universal Debugger) is KSR's interactive source level debugger for serial and parallel programs written in KSR Fortran, KSR C and KSR1 assembly language. Udb is a source level debugger for testing and debugging serial and parallel programs; it is compatible with GDB and dbx. The user can direct udb either by typing commands or graphically through an X-based window interface; the latter provides simultaneous display of source code, I/O and instructions. For parallel programs, operations can be carried out on a per thread basis. <description><url>http://www.tc.cornell.edu:80/Parallel.Tools/tools/udb.html </url> <reference><url></url> <contact> <keywords>parallel debugging; parallel processing tool <category>ppt-exe <publication-date> <environment>KSR <method> <application> <comments> </urc>
