The iThena distributed project concerns experimental mapping of network structures included in the Internet. The project is in closed beta phase. Currently, the only application available in the project (iThena CNode) performs a sequence of traceroute procedures from client computers. The resulting data is sent back to the server and submitted to the main database, where it can be further analyzed.

Currently the main supported and recommended platform is x86_64-pc-linux-gnu, windows_intelx86 and windows_x86_64. After joining the project, accept the download of test/beta applications in the settings (all currently applications is in a Beta stage). This can be changed by checking the appropriate box 'Run test applications?' in 'iThena preferences' in your profile after logging in.

Network structure mapping summaries will be available online.

Two applications are currently active: iThena CNode and iThena PERF.
The iThena CNode application tests delays, possible losses and routing of network packets.
The iThena PERF application mainly tests bandwidth to defined endpoints.

iThena Cnode application - new credits settings
According to the forum post:

I'm going to introduce better credit for Thena CNode tasks.

I will initially set 2 credits per task.

New settings will only be visible after a certain period of time.

The current tasks still have the old configuration. However, the new tasks will already have higher credit values.

The update of the historical "cnode beta" series badges has been disabled.
These badges will no longer be changed.

[June 28th, 2020] Maintenance interruption in access to the system
Today (June 28th, 2020) evening of the UTC time I plan a relatively short break in the availability of the iThena project.

This break will apply to all services of the iThena project in BOINC.

The break should last about 1-2 hours.

Sorry for the problems!

iThena PERF version 1.03 - platforms windows_intelx86 and x86_64-pc-linux-gnu
I added iThena PERF application version 1.03 for platforms windows_intelx86 and x86_64-pc-linux-gnu.

The application for Windows requires Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019.

Theoretically, the problem with "freezing" should disappear in this version of the application.

Please inform me about possible problems ;)
