[iThena] 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:

[iThena] 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] 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).

[Universe@Home] Maintenance break

As I inform recently in other topic we have planned maintenance break for CAMK power transform replacement on this weekend.
Our server will be switched off today (25.11) till Monday, 28.11.

I hope this change will go smoothly and we come back to normal work on Monday morning/afternoon.

[SRBase] Downtime on Friday

There will be a downtime tomorrow for some updates and an undervolting test.
The PBO limit is too high and must be changed in BIOS. The CPU is reaching 95°C easily under heavy load which is not good.

Iam expecting 1h for stresstest. The server will not be available at this time.

[RakeSearch] Processing of the square # 19 completed

Dear participants, processing of the square # 19 is fully completed! The square:

0 1 2 3 4 5 6 7 8 9 A B
1 2 0 4 5 3 8 6 7 B 9 A
2 0 1 5 3 4 7 8 6 A B 9
8 7 6 9 B A 1 0 2 5 4 3
7 6 8 B A 9 2 1 0 3 5 4
B A 9 8 7 6 5 4 3 2 1 0
5 3 4 1 2 0 B 9 A 7 8 6
9 B A 6 8 7 4 3 5 1 0 2
A 9 B 7 6 8 3 5 4 0 2 1
4 5 3 0 1 2 9 A B 8 6 7
3 4 5 2 0 1 A B 9 6 7 8
6 8 7 A 9 B 0 2 1 4 3 5

has 1228403532 orthogonal mates which would puts it on the 4th place of the rating, but another square - #17 already placed on it with equivalent number of orthogonal mates! This is very unexpected because each of the squares is a separate canonical form and cannot be converted into another square by M-transformations. But one square can be transformed into another square by rows and columns permutations. Usually this permutations break the diagonality of squares, but not in this case! Very interesting finding!

Now whole spectra of ODLS-12 globally looks like this (one point is not a single number):

Thank you for participation and donation of CPU Time!

[Asteroids@home] New FMA application released

We are happy to present you another set of applications that will utilize those CPUs, which possess the FMA instruction set!

It was built to support both Linux and Windows OS with 64bit architecture.
What must be taken into account with these applications is that depending on the CPU architecture, generation, model, version, speed and number of utilized cores, in some cases the FMA applications may run slower than the corresponding AVX ones because of how those instructions are handled on different architectures, details that I'll not going further here as there is a lot of information on Internet. Also, there could be another case using even the same FMA application. For instance, there could be a situation where on the same particular system, having your preferences restrict the use of just a single core of, let's say, an Intel(R) Xeon(R) W Processor Xeon W-2195 of the Skylake-W Architecture, that single core will run much faster, close to processors' Turbo frequency of 4.3GHz, than if your configuration allows the client to utilize let's say 12 or more cores. In the second case those cores will run close to the processors' base frequency of 2.3GHz, depending on their actual number, which will result drastically in lowering of the application performance. Take a look at this article where under the "Per Core Turbo Data" chapter you will find explanation about how the Turbo ratio limits works.

Still, while the Boinc server is capable of finding the best performed application for every particular system, taking into account multiple factors, and after a while it will start sending the right one for every particular system. Which means that even if your CPU is equipped with the FMA engine it still might receive an AVX tasks and there is nothing to be concerned.

So happy crunching and thank you for your support!

[Asteroids@home] New CUDA application released

We are happy to present you our latest CUDA application v102.16!

It was built on top of CUDA's v11.8 SDK and thus it will be able to utilize the vast majority of cards with Compute Capabilities (CC) between 5.0 till 8.9 adding support for the Ampere & Ada Lovelace micro architecture, and all the Tegra & Jetson modules.
Of course, it comes with its own requirements for the driver's versions, depending on your architecture, as those before it.
In order your client to be able to receive it your computer must have one of the following Nvidia driver versions installed:


Here is the list of supported by the v102.16 application GPUs by their CC provided by Nvidia.

So happy crunching and thank you for your support!

[SIDock@home] BOINC Census 2022, be counted!

The BOINC Census is a yearly effort aimed at finding out who uses BOINC, what they like about it, and what changes they want to see in the future. Filling out the census is a great way to support this project, the wider BOINC community, and have your input heard for future bug bounties. The census is sponsored by the Science Commons Initiative, and the results will be published in an aggregate, anonymized fashion at the completion of the census. Please take 5 minutes to fill out the census at

[SIDock@home] Target 21: corona_TMPRSS2_v1

Dear Participants,

TMPRSS2 is a type II transmembrane protease with broad expression in epithelial cells of the respiratory and gastrointestinal human tracts. It is a cofactor in SARS-CoV-2 entry, and primes viral proteins. Namely, TMPRSS2 cleaves the viral Spro to expose the fusion peptide for cell entry. We are therefore examining TMPRSS2 as a promising strategy to block viral infection in a host-directed therapeutic and/or prophylactic manner. This work is also a a part of larger viral-host protease inhibition study campaign.

With best wishes,
Team SiDock@home

[Asteroids@home] Server is up and running again

Hi everyone,

Server is finally up and running again after more than a year of being down. Everything is migrated to a new server and we hope it will run smoothly for a long time. There are still some minor issues but nothing crutial and all minor tweeks will be done during the time.
I would also like to thank to Georgi Vidinski who has helped with solving some problems.
