HASSE: a Tool for Analyzing Causal Relationships in Parallel and Distributed Systems
نویسندگان
چکیده
As the causal relationships induced by communication between cooperating processes are crucial for understanding the dynamic behavior of parallel and distributed systems, tool support is needed for analyzing them. This paper presents hasse, a tool which graphically represents the event traces from cooperating processes according to a formal description of their causal interdependences. Hasse allows to interactively zoom and further analyze the systems' activities shown. Especially the ability to automatically determine and display the pre-area and post-area of selected events is an important aid for determining the cause of an observed undesired behavior.

Static Task Allocation in Distributed Systems Using Parallel Genetic Algorithm
Over the past two decades, PC speeds have increased from a few instructions per second to several million instructions per second. The tremendous speed of today's networks as well as the increasing need for high-performance systems has made researchers interested in parallel and distributed computing. The rapid growth of distributed systems has led to a variety of problems. Task allocation is a...
متن کاملVisualization of Causal Relations
The notion of cause and effect is pervasive in human thinking and plays a significant role in our perception of time. Software systems, in particular parallel and distributed ones, are permeated by this causality, and the human mind is especially well-suited to detect instances of this concept. Unfortunately, realworld systems of causally related events are often too large and complex to be com...

Causality visualization is an important tool for many scientific domains that involve complex interactions between multiple entities (examples include parallel and distributed systems in computer science). However, traditional visualization techniques such as Hasse diagrams are not well-suited to large system executions, and users often have difficulties answering even basic questions using the...
متن کاملAnalyzing the Causal Relationships between Economic Growth, Income Inequality, and Transmission Channels: New Empirical Evidences from Iran
This paper investigates causal relations between economic growth, income inequality, and transmission channels during the period 1972 to 2016. These channels include saving rate, investment rate, redistribution policies, human capital, and conspicuous consumption. There is no strong evidence that supports uni-directional or bi-directional causality. In addition, some of the transmission channel...
متن کاملEfficient Vector Time with Dynamic Process Creation and Termination
Many distributed algorithms require knowledge of the causal relationships between events. Examples include optimistic recovery protocols, distributed debugging systems, and causal distributed shared memory. Determining causal relationships can be difficult, however, because there is no global clock and local clocks cannot be perfectly synchronized. Vector time is a useful abstraction for captur...
