From the attached image, the client was able to connect successfully to the server, download some workunits and start working on them. It hasn't finished them yet, so I don't know about the uploading of the results.

As I look into the server log, I see that these assignments were successfully returned in approximately 2 hours and 12 minutes. That is perfect, thank you!

Almost solved(!), Terence Tao has made a big progress on Collatz conjecture: https://arxiv.org/pdf/1909.03562.pdf

In the arxiv preprint, Definition 1.2 has

\text{for all }A\;\subset\;S

which threw me for a loop, since "S" was not defined.

It was a typo. Tao's page (thanks, retina!) says it should be

\text{for all }A\;\subset\;\mathbb{N}\;+\;1

Default Any help still welcome

Any help with this distributed computation is still welcome. All you need to do is to compile the client from this GitHub repository. The source codes require a GNU toolchain. They can also be compiled on MS Windows (see above discussion).

I could be boring, but this type of task is ideal for the much faster gpu.

I'm sure you're right about this. However, now I don't known any person able to implement it on the GPU right now.

PS: Linux binaries are also available on the project page.

My project has evolved a lot in the last month. Now I use modern (massively parallel) GPUs to verify the problem convergence. This brings an acceleration of more than two orders of magnitude. At this moment, I would welcome any help regarding the GPU implementation. Could anyone review my code in OpenCL on StackExchange?

After less than a year, I managed to verify all numbers below 268 in this way. For those who are interested, the results are presented in this article.
