【Abstract】 DENNET is a debugging environment for cluster systems developed by Tsinghua University. After analyzing the researching trend of debugging environments, we point out the problem of disturbance that a debugging environment imposed on a debugged parallel program. Reduction, even complete elimination this disturbance is an important researching direction in the field of debugging environment. We also present a prototype of debugging environment-DENNET that shows the applications of some techniques of reducing disturbance.更多还原
