Infrastructure problems (LTO)
Within the infrastructure problems are the needs for mass data storage.

We need an LTO drive or LTO library.
Alternatively, LTO tapes themselves may also be useful.

The preferred LTO generation is LTO4 or LTO5.

If anyone has any in their storeroom/basement/garage :) we are happy to accept this type of equipment for our own needs.

Perhaps it is just taking up unnecessary space at someone's place.

If anyone knows anything about this type of equipment, please send us an e-mail:

Thena.Computational and GridCoin
Further to an earlier announcement, we are planning to add the iThena.Computational project to GridCoin.

However, the possible final date for adding iThena.Computational to GridCoin is not yet known.

Soon the iThena GRAPH tasks will be finished. Currently, we are not generating new GRAPH tasks - however, we are planning to update the GRAPH application and add Windows support for the HEX application.

The above changes apply to the iThena.Computational subproject.

iThena.Computational: Organizational information
We are currently implementing the iThena HEX application.
This application is now available for Linux 32-bit and 64-bit platforms.

We plan to add support for Windows 32-bit and 64-bit platforms in the near future.

The iThena HEX application has quorum=2 (verification by wingman).

We will currently stop generating new tasks in the iThena GRAPH application. This application will be modified. Current tasks (also available in the queue on the server) will be available normally.
No new tasks will be generated for iThena GRAPH until the tasks are updated.

We plan to integrate the iThena.Computational project with GridCoin.

The iThena.Measurements project has a lot of problems (frequent storage issue) and on at this time it is not possible.

The integration of iThena.Computational with GridCoin also automatically forces us to improve system availability (the system must be online).

Open-Source Proxmox platform as part of the infrastructure

As part of our own initiatives we use open-source software.

Such systems based on open-source model are BOINC, and Elastic Stack.

We use advanced virtualization technologies and LXC containers based on Proxmox Virtual Environment.

Following the information on Wikipedia:

Proxmox Virtual Environment is an open-source server virtualization management platform. It is a Debian-based Linux distribution with a modified Ubuntu LTS kernel and allows deployment and management of virtual machines and containers. Proxmox VE includes a web console and command-line tools, and provides a REST API for third-party tools.

Open-source models built by communities in a huge way are very interesting.

We encourage you to support open-source initiatives and take advantage of such environments!

Dedicated DNS servers available (as part of optimization)
Applications (especially CNode) can now make significant use of DNS servers.

To avoid overloading other servers (not necessarily your ISP) you can use our DNS servers:
Location: Germany/Frankfurt
IPv6: 2001:41d0:701:1100::452
Location: Canada/Beauharnois
IPv6: 2607:5300:101:0:0:0:0:75d
Location: Poland/Warsaw
IPv6: fe80::250:56ff:fea9:8da0
Location: Australia/Sydney
IPv6: 2402:1f00:8100:400::125a

You can also set up your own DNS server (or just DNS cache) on your LAN.
This is especially important if you have several/many BOINC clients and CNode app.
You can check which of the above DNS will be the best (geolocation).

Q1 2021: Planned hardware upgrade of the iThena BOINC platform
A major hardware upgrade of the BOINC server is planned for Q1 2021.

Currently, the BOINC platform shares hardware resources within the framework of virtualization.

I plan to separate the BOINC platform into dedicated hardware resources (dedicated server).

This server will probably run on 15k SAS drives (mirroring) with double socket Intel Xeon CPU.

If somebody has unnecessary SAS hard drives (15k or even 10k) or some RAM (DDR3 ECC/non-ECC), these are components that can be very useful in hardware system;)

In case someone would like to donate this type of hardware to the project or have other interesting components (also network equipment) can contact me by email:

In Q1 2021, we also plan to make a significant upgrade of the Internet access link.

August 29, 2020: 1 year of the iThena Project!

Approximately one year ago (August 29, 2019) we launched the iThena Project on the BOINC platform!

As a system administrator I would like to thank all users for their time and help in developing the platform.

In this message I should include more information about future plans, of which there are many.
However, I don't want to reveal all the plans - there are still many things in development.

There are many different technical problems in the project. Sometimes there are new problems. I try to fight the problems as much as possible. But sometimes such a fight takes a lot of time - we can't build everything very quickly (with limited daily time).

In the near future I plan to add new badges. Here was a thread about it on the forum:

The iThena PERF application should also return to the platform permanently and the tasks for this application should be available all the time.

To improve the contact I decided to create a dedicated Twitter account: @iThenaProject.
The latest information will be posted on Twitter. Of course, it will also be on the official project website.

Use the "Following" option on Twitter!

Many thanks for all your help!

August 28, 2020: iThena PERF application reactivation tests
On August 28, 2020 I am planning the first tests of reactivation of iThena PERF application tasks.

The tests will start in the afternoon (UTC Time).

The tests will also be connected with the necessity to perform several servers reboots (the system may be unavailable for a short time).

iThena CNode (non-beta) badge - badge graphics proposals
A few days ago, Thena CNode beta badges were frozen.

These badges were introduced in this message:

The old iThena CNode badge (beta stage) will no longer be updated.

Maybe you have suggestions for the next generation of badges for iThena CNode?

You can submit your suggestions and/or ideas in this thread in the forum.

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.

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.

Maintenance and new version of iThena PERF application - Linux platform
Today (i.e. 5 April 2020) around 21:00 UTC I plan to shut down the BOINC server. The planned shutdown is due to the continuation of re-implementation works described in the thread:

The interruptions may take several hours. However, the server should be online in the morning of 6 April (or even earlier).

Additionally, it is planned to implement a new version of iThena PERF application. Also Linux versions (first of all: x86_64-pc-linux-gnu).

The first (test) version (v1.01) of iThena PERF is available at the address:

You can download it.
We start executing it by running ithena_perf_v1.01_x86_64-pc-linux-gnu files in the uncompressed directory:


Please help with the first tests.
The application generates a load on your computer network (standard load).
You can send questions and results (files result_*.dat and stderr.txt) to my e-mail address: lswierczewski [at]

This version for Linux should no longer be able to calculate in infinite time... New version of Windows (in progress) won't have this problem either.

Send me a message to tell me if everything is okay.

Project availability interruption

The break will be caused by a change in virtualization technology on one of the servers - migration from VirtualBOX to VMware ESXi.

I will probably try to migrate tomorrow (29.03.2020).

I will inform about the changes.

Network situation related to the general state of the SARS-CoV-2 pandemic
Today I introduced a new iThena PERF application for Windows platforms (the application works on both 32 and 64-bit systems).

Next tasks will be iThena PERF will generate real credits for users.

However, the iThena CNode application is also very important for this moment.

The iThena PERF application tests mainly the overall performance (bandwidth of client/server performance nodes) of the Internet network. The software base here is iperf3 open app.

iThena CNode is much more focused on mapping the Internet network including delays (hops). The software base here is traceroute solutions.

Due to the general situation related to the SARS-CoV-2 pandemic, deviations in Internet network structures are very interesting. For this reason I strongly encourage you to participate in the project.

Measurements can also be interesting in the sense of crisis management of network infrastructure and increased use of network resources related to the situation.

In the coming days I also plan to better solve the "age-old problem of small loans".

An Internet connection is required.

Current situation in the world: Networks

Due to the current situation in the world I have a request to BOINC users.

Due to the problem of network systems usage (currently occurring overload) I would like more people to run iThena CNode application.

I plan to add a new application for Windows (32 and 64-bit). However, it will be a bit different type of application.

However, the results from iThena CNode application are very interesting for me.

iThena CNode does not use the computer network very critically.

New application, new possibilities, new problems ;)
I will soon be implementing a new application ;)
The application will be called iThena NRT.

The credit problem will be solved.

The tasks for iThena CNode will be phased out.

However, there are many problems.
Initially, iThena NRT will be available as a virtualised environment (VBox/Vmware). You will be able to start a virtual system.

Of course it will also be possible to run it locally.

In addition, the iThena NRT application will require a permanent connection to the Internet.

Geolocation of network points data
One of the important information in network analysis is the geolocation of network points data.

There is no generally available, one coherent database covering very precise data.

The problem is well known by engineers and researchers.

There are of course some (not perfect) solutions but often the error is big.

I will probably implement a mechanism enabling the platform user to provide location information for a given client.

This is a longer planning period.

Also remember that providing such information is only optional.
This will definitely not be a requirement.

If you have questions or concerns, I encourage everyone to discuss.

Badges for beta stage - iThena CNode
Today I introduced first badges for users (for beta stage).

We have three degrees of beta stage badges:

- bronze:
- silver:
- gold:

We have the following thresholds for these badges:

Gold badge for beta stage >= 0.10 total credit
(average 30030 wu at 0.00000333 credit per wu)

Silver beta badge >= 0.025 total credit
(average of 7507 wu at 0.00000333 credit per wu)

Bronze badge for beta stage >= 0.010 total credit
(average of 3003 wu at 0.00000333 credit per wu)

Only the highest possible badge is awarded.

Deadline on January 1, 2020 is probably not bad ;)
We will pre-implement this date.
