fUML-Driven Design and Performance Analysis of Software Agents for Wireless S...Luca Berardinelli
The growing request for high-quality applications for Wireless Sensor Network (WSN) demands model-driven approaches that facilitate the design and the early validation of extra-functional properties by combining design and analysis models. For this purpose, UML and several analysis-specific languages can be chosen and weaved through translational approaches. However, the complexity brought by the underlying technological spaces may hinder the adoption of UML-based approaches in the WSN domain. The recently introduced Foundational UML (fUML) standard provides a formal semantics to a strict UML subset, enabling the execution of UML models.
Leveraging fUML, we realize the Agilla Modeling Framework, an executable fUML model library, to conveniently design agent-based software applications for WSN and analyze their performance through the execution of the corresponding fUML model. A running case study is provided to show our framework at work.

Automatically bridging UML profiles into MOF metamodelsIvano Malavolta
27th August 2015. My presentation at SEAA 2015 (http://paginas.fe.up.pt/~dsd-seaa-2015/) about our approach for autmatically bridging UML profiles into MOF metamodels. SEAA 2015 is the 41st Euromicro Conference on Software Engineering and Advanced Applications, and it has been held in 26 - 28 August 2015, Funchal, Madeira, Portugal.

http://www.ivanomalavolta.com/files/papers/SEAA_2015.pdf
Abstract:
In Model-Driven Engineering, UML profiles and MOF-based Domain Specific Modeling Languages (DSMLs) are the most used approaches for describing domain specific applications. The choice of the right approach depends on several aspects, such as tool support, expressivity, complexity of models, company policies. In general, profiled UML models are very much used since they are intuitive for designers and model editors already exist, however they are intrinsically complex for model manipulation (e.g., transformation, analysis); conversely, domain specific models are more concise and easy to be manipulated, but they require an initial effort in terms of designers training and model editors development.
In this paper we propose an approach that allows getting the best of the two worlds: on one side designers can use UML profiles familiar to them, on the other side DSML models (automatically generated from profiled UML models) enable a better model manipulation. Our approach is based on an automatic bridge between UML profiles and MOF metamodels (which are the main artifacts of MOF-based DSMLs). The bridge is transparent to the user since it autonomously operates both on UML profiles and all the involved models. The bridge is realized through model transformation techniques in the Eclipse platform. In this paper we show its application on a case study based on SysML.

Spark Autotuning: Spark Summit East talk by Lawrence SpracklenSpark Summit
While the performance delivered by Spark has enabled data scientists to undertake sophisticated analyses on big and complex data in actionable timeframes, too often, the process of manually configuring the underlying Spark jobs (including the number and size of the executors) can be a significant and time consuming undertaking. Not only it does this configuration process typically rely heavily on repeated trial-and-error, it necessitates that data scientists have a low-level understanding of Spark and detailed cluster sizing information. At Alpine Data we have been working to eliminate this requirement, and develop algorithms that can be used to automatically tune Spark jobs with minimal user involvement,
In this presentation, we discuss the algorithms we have developed and illustrate how they leverage information about the size of the data being analyzed, the analytical operations being used in the flow, the cluster size, configuration and real-time utilization, to automatically determine the optimal Spark job configuration for peak performance.

Conducting Experiments on the Software Architecture of Robotic Systems (QRARS...Ivano Malavolta
Slides of my invited talk at the 2nd workshop on Quality and Reliability Assessment of Robotic Software Architectures and Components (QRARSAC), co-located with the International Conference on Robotics and Automation (ICRA 2023).
Abstract of the talk. Today robotic systems are central to many industrial sectors, such as logistics, autonomous warehousing, and healthcare. If on one side ROS is helping roboticists by providing a standardized communication platform for robotic systems, on the other side ROSsystems are getting more and more large and complex, thus making it extremely difficult to ensure their level of quality, e.g., in terms of performance, security, energy efficiency, testability, maintainability. Improving the quality of robotic systems is not a new activity, but in this talk, we tackle it from a different perspective: we look at them from a software architecture perspective. In this talk, I will walk you through a series of experiments we conducted at the Vrije Universiteit Amsterdam targeting the architecture of ROS systems, we will discuss some architectural tactics for ROS systems, and will close with an overview of our open-source tool for automatically executing experiments on robotics software.
The slides of a short presentation I gave about my experience about working in the context of EU grants. It contains tips and tricks for the before/during/after phases of a EU project.

Globus Compute wth IRI Workflows - GlobusWorld 2024Globus
As part of the DOE Integrated Research Infrastructure (IRI) program, NERSC at Lawrence Berkeley National Lab and ALCF at Argonne National Lab are working closely with General Atomics on accelerating the computing requirements of the DIII-D experiment. As part of the work the team is investigating ways to speedup the time to solution for many different parts of the DIII-D workflow including how they run jobs on HPC systems. One of these routes is looking at Globus Compute as a way to replace the current method for managing tasks and we describe a brief proof of concept showing how Globus Compute could help to schedule jobs and be a tool to connect compute at different facilities.
Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

8. Three levels of description
• Category (predefined)
• Type
– specification of the external interface
• Implementation
– specification of the content
• Instance
– instantiation of a type
or an implementation
– you do not model it, it is created by the tool
9. Software components categories
• Process : address space. It must
hold at least one thread
• Thread : schedulable execution
flow, Ada or VxWorks task, Java
or POSIX thread. Executes
programs
• Data : data placeholder, e.g. C
struct, C++ class, Ada record
• Subprogram : a sequential
execution flow. Associated to a
source code (C, Java) or a model
(Simulink)
• Thread group : hierarchy of
threads
10. Software components
Example: process composed of two threads
thread receiver
end receiver;
thread implementation receiver.impl
end receiver.impl;
thread analyser
end analyser;
thread implementation analyser.impl
end analyser.impl;
process processing
end processing;
process implementation processing.others
subcomponents
receive : thread receiver.impl;
analyse : thread analyser.impl;
. . .
end processing.others;
11. Software components
a thread may call different subprograms
thread receiver
end receiver;
thread implementation receiver.impl
calls CS : {
call1 : subprogram Receiver_Spg;
call2 : subprogram ComputeCRC_Spg;
};
end receiver.impl;
subprogram Receiver_Spg
end Receiver_Spg;
subprogram ComputeCRC_Spg
end ComputeCRC_Spg;

19. Subprogram
A subprogram component represents an execution entry point in source
text
No component can contain subprogram subcomponents.
A subprogram call in the implementation of a thread or another
subprogram may be “seen as” the inclusion of a subprogram
subcomponent
A thread can have call sequences for its states:
– initialization, finalization, activation, deactivation, computation, and recovery
Each thread dispatch executes the computation call sequence once
23. Data
It represents static data (e.g., numerical data or source text)
and data types within a system
– (e.g., used as data types on ports and parameters)
Components may have a shared access to a data
component
Good practice: to store data definitions in a separate file
30. Modes
A mode represents an operational state of a system
A mode of a component can influence:
– property values
– activation of specific subcomponents
– existence of connections
Example - Modes of a cruise controller:
{initialize, disengaged, engaged}
31. Modes transitions
Mode transitions represent configuration changes as reaction
to events
– Triggered through ports (from outside or from a subcomponent)
– Triggered internally by implementation software
– Triggered internally in an execution platform component or a
device
• Note: Modes are not intended for modeling detailed
internal behavior of threads or subprograms ( AADL
Behavior Annex)

35. Hardware components categories
• Processor/virtual processor
– schedule component (combined CPU and RTOS scheduler). A
processor may contain multiple virtual processors
• memory
– model data storage (memory, hard drive)
• device
– component that interacts with the environment.
• internals (e.g. firmware) is not modeled.
• bus/virtual bus
– data exchange mechanism between hardware components
Device Memory bus Processor
44. Software/platform binding
• Actual_Processor_Binding
– Specify which processor schedules and executes a thread or
executes a (kernel mode) device driver
• Actual_Memory_Binding
– Specify the memory components in which executable code
(process components) and data (data component) reside
• Actual_Connection_Binding
– Specify the communication channels that are used by logical
connections (see next section)

48. Property sets
Property sets :
– Group property definitions
– They can be either
• part of the standard, e.g. Thread_Properties
• or user-defined, e.g. for a new analysis
Example :
property set Thread_Properties is
. . .
Priority : aadlinteger applies to (thread, device, …);
Source_Text : inherit list of aadlstring applies to (data, port, thread, …);
. . .
end Thread_Properties;
50. AADL properties
Property:
– Typed attribute, associated to one or more components
– Property = name + type + allowed components
– Property association = property name + value
Allowed types in properties:
– aadlboolean, aadlinteger, aadlreal, aadlstring,
enumeration, many others …
Can be propagated to subcomponents: inherit
Can override parent’s one, case of extends
52. AADL properties
Properties are associated to a component type (1) or
implementation (2), as part of a subcomponent instance (3),
or a contained property association (4).

Deadline => 150 ms ;
end receiver;
thread implementation receiver.impl
properties -- (2)
Deadline => 160 ms;
Compute_Execution_Time => 4ms .. 10ms;
end receiver.impl;
53. Measurement units
Properties are typed with units to model physical systems,
related to embedded real-time critical systems
property set AADL_Projects is
Time_Units: type units (
ps,
ns => ps * 1000,
us => ns * 1000,
ms => us * 1000,
sec => ms * 1000,
min => sec * 60,
hr => min * 60);
-- …
end AADL_Projects;
property set Timing_Properties is
Time: type aadlinteger
0ps .. Max_Time units Time_Units;
Time_Range: type range of Time;
Compute_Execution_Time: Time_Range
applies to (thread, device, subprogram,
event port, event data port);
end Timing_Properties;

55. AADL packages
A package provides a means to organize the descriptions by
the use of namespaces
A package can contain:
– component types
– component implementations
– port group types
– annex libraries
57. AADL systems
Help structuring an architecture, with its own hierarchy of
subcomponents.
A system can include one or several subsystems
In an AADL specification there is always a root system
component

59. A full AADL system : a tree of
component instances
• Component types and
implementations only define a
library of entities (classifiers)
• An AADL model is a set of
component instances (of the
classifiers)
• System must be instantiated
through a hierarchy of
subcomponents, from root
(system) to the leafs
(subprograms, ..)
• We must choose a system
implementation component as
the root system model !

61. System instances
Component types and implementations are “only” blueprints
A system instance represents the runtime architecture of an
operational physical system
Composed of software components + execution platform
XML for storing system instances
62. System instances 2
System instances are automatically generated by OSATE
starting from complete system implementations
63. Components extension & refinement
Extension: to define a new extended classifier based on an
existing classifier
Allows incremental refinement of a model
• Component extension
– Component types
– Component implementations
72. Example
Goal: to model a simple radar system
Let us suppose we have the following requirements:
1. System implementation is composed of physical devices (Hardware
entity): antenna + processor + memory + bus
2. and software entities : running processes and threads + operating system
functionalities (scheduling) implemented in the processor that represents
a part of execution platform and physical devices in the same time
3. The main process is responsible for signals processing : general pattern:
transmitter -> antenna -> receiver -> analyzer -> display
4. Analyzer is a periodic thread that compares transmitted and received
signals to perform detection, localization and identification

81. What this lecture means to you?
AADL = Architecture Analysis & Design Language
AADL is for architectural description, period.
à Not to be compared with UML suites
– Behavior, types, link with source code is not required
Keep in mind models support an objective
What is not covered by this lecture:
flows, annexes, multidimensional arrays, virtual
processors/buses, analyses with external tools
