Trace Visualization

Pajé

The Pajé generic tool provides interactive and scalable behavioral visualizations of parallel and distributed applications, helping to capture the dynamics of their executions; because of its genericity, it can be used unchanged in a large variety of contexts.

Pajé Next Generation

Pajé Next Generation is a re-implementation (in C++) and direct heir of the well-known Paje visualization tool for the analysis of execution traces (in the Paje File Format) through trace visualization (space/time view). The tool is released under the GNU General Public License 3. PajeNG comprises the libpaje library, the space-time visualization tool in pajeng and a set of auxiliary tools to manage Paje trace files (such as pj_dump and pj_validate). It was started as part of the french INFRA-SONGS ANR project. Development has continued at INF/UFRGS.

Viva

Viva is an open-source tool used to analyze traces (in the Paje File Format) registered during the execution of parallel or distributed applications. The tool also serves as a sandbox to the development of new visualization techniques. Current features include:

• Temporal integration using dynamic time-intervals
• Spatial aggregation through hierarchical traces
• Interactive Graph Visualization with a force-directed algorithm, with viva
• Squarified Treemap to compare processes behavior on scale, with vv_treemap

Framesoc

Framesoc is the core software infrastructure of the SoC-Trace project. It provides a graphical user environment for execution-trace analysis, featuring interactive analysis views as Gantt charts or statistics views. It provides also a software library to store generic trace data, play with them, and build other analysis tools (e.g., Ocelotl). This software is developed in partnership with Nanosim.

Ocelotl

Ocelotl: Multidimensional Overviews for Huge Trace Analysis is an innovative visualization tool, which provides overviews for execution trace analysis by using a data aggregation technique. This technique enables to find anomalies in huge traces containing up to several billions of events, while keeping a fast computation time and providing a simple representation that does not overload the user.

Simulation and performance evaluation

Ψ ²

PSI (Perfect Simulator) is a simulation software of markovian models. It be able to simulate discrete and continuous time models to provide a perfect sampling of the stationary distribution or directly a sampling of functional of this distribution. The simulation kernel is based on the CFTP algorithm, and the internal simulation of transitions on the Aliasing method.

SimGrid

SimGrid is a toolkit that provides core functionalities for the simulation of distributed applications in heterogeneous distributed environments. The specific goal of the project is to facilitate research in the area of distributed and parallel application scheduling on distributed computing platforms ranging from simple network of workstations to Computational Grids.

PEPS

The main objective of PEPS is to facilitate the solution of large discrete event systems, in situations where classical methods fail. PEPS may be applied to the modelling of computer systems, telecommunication systems, road traffic, or manufacturing systems.

GameSeer

GameSeer is a tool for students and researchers in game theory that uses Mathematica to generate phase portraits for normal form games under a variety of (user-customizable) evolutionary dynamics. The whole point behind GameSeer is to provide a dynamic graphical interface that allows the user to employ Mathematica's vast numerical capabilities from a simple and intuitive front-end. So, even if you've never used Mathematica before, you should be able to generate fully editable and customizable portraits quickly and painlessly. Download GameSeer

Grid Middleware

OAR

The OAR batch scheduler is based on a database (MySQL), a script language (Perl) and an optional scalable administrative tool (component of Taktuk framework). It is composed of modules which interact only with database and are executed as independent programs. So formally, there is no API, the system is completely defined by the database schema. This approach eases the development of specific modules. Indeed, each module (such as schedulers) may be developed in any language having a database access library.

CiGri

CiGri is a lightweight grid middleware co-developed with Ciment and Grid'5000

Computemode: On-demand HPC cluster manager

(partnership with Andra)

ComputeMode is an software infrastructure that allows to extends or create a Grid through the aggregation of unused computing resources. For instance, a virtual cluster can be built using anyone's PC while not in use. Indeed, most PCs in large companies or university campus are idle at night, on weekends, and during vacations, training periods or business trips.

Tools That Ease Experiment Reproducibility

Kadeploy

Kadeploy is a fast and scalable deployment system for clusters and grids. It provides a set of tools for cloning, configuring (post installation) and managing a set of nodes. Currently it can successfully deploy Linux, *BSD, Windows and Solaris on x86 and 64 bits computers.

Kameleon

Kameleon is a simple but powerful tool to generate customized appliances. With Kameleon, you make your recipe that describes how to create step by step your own distribution. At start Kameleon is used to create custom kvm, docker, VirtualBox, ..., but as it is designed to be very generic you can probably do a lot more than that.
