Book Release

This text intends to be a comprehensive and substantially self-contained two-volume book covering performance, reliability, and availability evaluation subjects. The volumes focus on computing systems, although the methods may also be applied to other systems. Like many parallel or concurrent systems, computing systems often lead to conflicts because processes attempt to access resources simultaneously or with time overlapping. Such conflict may cause errors, process congestion, and system deadlocks. Moreover, when planning a cost-effective system, the policies, mechanisms, systems’ structures, and the respective phenomena are usually hard to represent by deterministic models.

On the other hand, such systems commonly have statistical regularities that make them suitable for dealing with stochastic processes and statistics that quantify the collected data’s central tendencies, variability, and shapes. Due to its size, the document was divided into two volumes. The first volume covers from Chapter 1 to Chapter 14, whose subtitle is “Performance Modeling and Background.” The second volume encompasses from Chapter 16 to Chapter 26 and has the subtitle “Reliability and Availability Modeling, Measuring and Workload, and Lifetime Data Analysis.”

New Version of Mercury Tool Available!

mercury-symbol

The version 6 of Mercury has been released.

 

Dear Colleagues,

We are pleased to announce that version 6 of the Mercury tool has been released to the industry and academic community.

This new version fixes several bugs found in previous versions and introduces many new features and enhancements.

If you are a Mercury user, we strongly recommend getting the new version.

We hope you will enjoy it. If you have any suggestions or find any bugs, please report them to us.

If you do not know the tool yet and want to try it, please go to www.modcs.org and go to “Downloads” and “Mercury Tool”.

There, you will get a form, sign it, and download the tool.

What’s new in Mercury?

Below, we describe the most important features and enhancements of version 6:
    1. Event Tree Models
      1. Mercury now supports Event Tree models, enabling users to systematically represent and analyze sequential events and their outcomes.
    2. Support for Comments
      1. Users can now annotate models using Latex expressions and highlight certain elements for better documentation and emphasis.
    3. Support for Empirical Distributions
      1. Mercury now allows users to link empirical distributions to transitions in SPN models, increasing flexibility and accuracy in stochastic modeling.
    4. Log, Max, Min, and Power Functions in SPNs
      1. Introduces the Log function for different bases and adds Max, Min, and Power functions for advanced mathematical calculations.
    5. Constants Pi (PI) and Euler (e) in SPNs, CTMCs, and DTMCs
      1. Users can now construct expressions with mathematical constants Pi (PI) and Euler’s number (e), enabling more precise models.
    6. Edit SPN Components via Sidebar
      1. Provides an intuitive editing panel for SPN model components, simplifying the modification of properties.
    7. Other minor improvements and bug fixes.

What is the Mercury tool used for?

Mercury enables a range of models to be created and evaluated for supporting performance and dependability evaluations, such as reliability block diagrams (RBDs), dynamic RBDs (DRBDs), fault trees (FTs), event trees (ETs), energy flow models (EFMs), stochastic Petri nets (SPNs), and continuous and discrete-time Markov chains (CTMCs and DTMCs).

The tool has been cited in more than 140 scientific publications and used in over 18 countries worldwide.
Important notes on upgrading
Java 8 (1.8) is the recommended version of Java for running Mercury 6. Java 9 introduces the Java Platform Module System (JPMS), a new architectural design to which the tool has not yet been ported. We deliver Mercury 6 with the appropriate Java SE runtime environment (JRE) for Windows and *NIX systems. We also release the tool without the JRE, which is suitable for other environments. If you want to download Mercury without the JRE, you can find the recommended JRE
