[https://comp.ithena.net/usr/ '''''iThena.Computational'''''] is a '''''[[wikipedia:Volunteer computing|volunteer distributed computing]]''''' project based on the [[wikipedia:Berkeley Open Infrastructure for Network Computing|BOINC]] platform. The project focuses on experimental mapping and analysis of Internet network structures using volunteered computing resources from participants around the world.<ref name="about">{{cite web

The project is part of the broader '''iThena''' initiative, which is divided into two major subsystems:
 
* '''iThena.Computational''' – computational analysis and post-processing
* '''iThena.Measurements''' – active network measurement and traceroute collection<ref name="about" />
 
The project's goal is to create increasingly accurate models of the global Internet infrastructure, including routers, autonomous systems, points of presence (PoPs), latency relationships, and network topology characteristics.<ref>{{cite web

== History ==
 
The first test activities associated with the iThena project reportedly began on 29 August 2019.<ref>{{cite web

The first public announcement regarding the project was published on 26 September 2019.<ref>{{cite web

The name ''iThena'' is derived from a combination of the words ''Internet'' and ''Athena''.<ref>{{cite web

== Why iThena.Computational? ==
== Why iThena.Computational? ==


* why this topic/object of study?
Modern Internet infrastructure is extremely large, decentralized, and constantly changing. Mapping relationships between routers, autonomous systems, bandwidth paths, and latency characteristics requires massive numbers of distributed measurements and computational analysis steps.
 
The iThena project attempts to address these challenges by combining active network measurements with distributed post-processing using BOINC volunteers.<ref name="about" />
 
Unlike many BOINC projects focused on astronomy or biomedical research, iThena concentrates on network science and Internet topology analysis. The project gathers traceroute and bandwidth data from volunteer hosts distributed across many countries and network providers, allowing researchers to observe Internet structures from geographically diverse perspectives.<ref name="about" />


== Goal ==
== Goal ==
* summarize the objectives and challenges which the project addresses, before jumping into details


The primary objective of iThena.Computational is to analyze and transform data collected by the iThena.Measurements subsystem into usable network models and graph structures.<ref name="about" />
Specific goals include:
* Mapping Internet infrastructure topology
* Studying relationships between routers and autonomous systems
* Measuring latency and bandwidth characteristics
* Building graph-based representations of network structures
* Performing large-scale distributed graph computations
* Processing high-precision numerical transformations using volunteer computing resources<ref name="about" />
The project also aims to demonstrate how volunteer computing can be applied outside traditional scientific domains such as astrophysics or molecular biology.

[[File:Internet map 1024.jpg|thumb|300px|'''A high‑level visualization illustrating worldwide Internet interconnections and structural network topology.''']]
* impactful final statement
 
The project uses the [[wikipedia:Berkeley Open Infrastructure for Network Computing|BOINC]] middleware platform to distribute workloads to volunteer computers.<ref>{{cite web

BOINC enables large computational tasks to be split into smaller work units which are processed independently on participant computers and later returned to project servers for validation and aggregation.<ref>{{cite web

The iThena project contains several applications and subsystems:
 
=== GRAPH ===
 
The GRAPH application performs graph-processing operations on data collected from network measurements. It executes graph algorithms intended to analyze the structure of Internet infrastructure datasets.<ref name="about" />
 
Generation of new tasks for GRAPH has periodically been paused according to the project website.<ref name="about" />
 
=== HEX ===
 
HEX is a post-processing application that performs dynamic transformations on network measurement datasets. The application also performs calculations using the GNU MPFR high-precision arithmetic library.<ref name="about" />
 
HEX tasks use BOINC's quorum-based validation system, requiring agreement between multiple hosts before results are accepted.<ref name="about" />
 
=== CNODE ===
 
The CNODE application performs distributed traceroute operations from volunteer computers. Resulting data is uploaded back to project servers and integrated into the project's measurement database.<ref name="about" />
 
=== PERF ===
 
PERF performs bandwidth and network performance analyses using volunteer hosts.<ref name="about" />
 
=== OONI Probe integration ===
 
The project has also incorporated support for OONI Probe wrappers to assist with Internet measurement and network analysis activities.<ref name="about" />
 
[[File:IThena Project SectionA Graph 1000x1000.png|alt=example mediawiki image|thumb|'''Section A Graph (IThena Project)'''  Shows the computed results contributed by the network of BOINC volunteer clients.]]
 
The project's distributed approach allows measurements and analyses to be performed from many geographic regions simultaneously, providing broader visibility into Internet connectivity patterns.
 
== Supported platforms ==
 
The project primarily supports x86_64 Linux systems, although some applications are also available for Microsoft Windows.<ref name="about" />
 
Participants may need to enable BOINC beta or test applications in their account preferences to receive certain workloads such as CNODE.<ref name="about" />
 
== Statistics ==
 
Archived project statistics from October 2025 reported:
 
* 182,763 registered users
* 2,842 teams
* 4,907 hosts
* More than 238 million total credits awarded<ref>{{cite web
