At least we are back at 0.0001 levels so I can pick up some cheaper XEL to make me feel a little better..

You question is not clear...
If you meant to ask if Elastic can be used for real use cases, the answer is it will, after the full release is out. Speculative value as always, is up to the market to decide, just like any other project out there.

It's fucking Christmas, I can't believe people are dumping $XEL at these prices. I'm accumulating as much as I can.  Grin What are people thinking, is the whole China ban scaring them Huh People will look back and regret not believing in Elastic.

If you wish to use Elastic to perform tasks you will need to wait for the full client to be released. Updates about this will become available when it is relevant. You can check for announcements here, and in the slack and other info outlets.

Will Elastic node use GPU or only CPU for calculations? If it is limited to CPU only, I think it will be pretty much useless... However, even if it allows GPU, how the problem of data transfer is solved (GPU execution times are very small comparing to the time needed to transfer data between Elastic nodes)?

The node itself will perform no calculations at all, only verifications. The calculations are performed by the miner software, just like it is the case for Bitcoin and any other PoW coins. Currently, there is a prototypical CPU and a GPU version of xel_miner available. The "technological solutions" to solve the calculation tasks are however easily extendable by the community. I hope that we will see creative solutions sooner or later (quantum computing, FPGA circuits built on the fly, etc.)


However, even if it allows GPU, how the problem of data transfer is solved (GPU execution times are very small comparing to the time needed to transfer data between Elastic nodes)?

Can you elaborate more on this? Which scenarios do you have in mind? Which side cases are you concerned of? I mean, in the case of Bitcoin (in the early days before the ASICs came out) there were pretty efficient GPU miners available and they did nothing else than solving one particular calculation task (sha256d). The only difference (regarding the computation iteself) to XEL that I can see at the moment is: the calculation task now is dynamic instead of constant.

The only difference (regarding the computation iteself) to XEL that I can see at the moment is: the calculation task now is dynamic instead of constant.

My initial scenario was about digital image processing and video processing (Golem case). To handle video processing the whole video file needs to be uploaded to the miner, isn't it?

Another case is solving a huge system of differential equations (something about 10 millions of variables or more). For example, by Runge-Kutta method. The real use case for such systems is predictions (of cryptocurrencies' prices Grin). To solve such huge system the whole matrix needs to be uploaded as well.

My initial scenario was about digital image processing and video processing (Golem case). To handle video processing the whole video file needs to be uploaded to the miner, isn't it?

I would use Golem for that. They have specialized on that use-case and they can do it very good.

Another case is solving a huge system of differential equations (something about 10 millions of variables or more). For example, by Runge-Kutta method. The real use case for such systems is predictions (of cryptocurrencies' prices Grin). To solve such huge system the whole matrix needs to be uploaded as well.

Well, the Runge-Kutta method is not exactly the best choice in this case. What many people forget is that there are multiple types of parallelizm. The above method's parallelization potential falls into the first class called "parallelism across the method". Here, each computation core executes a different portion of the method itself. Because of complex interdependencies of variables in those different portions, the computational work per processor compared to the amount of data that needs to be exchanged between the cores can be assumed pretty low. Such methods are therefore more suitable for shared memory systems like multi processor rigs or GPUs. On the other hand, it does not matter whether you implement them in OpenMP, on the Elastic network, or some other distributed memory "cluster" ... in all cases you will face severe performance issues. This is not Elastic's fault.

This is the reason why it is mandatory to analyze which type of algorithm is suitable best for systems like Elastic. However, if the method is picked wisely. solving OBEs should not be undoable on distributed memory systems. One possibility would be to chose from methods from the category "parallelism accross the step". These do not require a constant exchange of data. Cores only need to communicate after each full iteration. Now, if each iteration has sufficient computational volume it might be worth a shot. However, i am not sure if step-parallel OBE solvers are the best choice anyway since the effective speed up (even for a large number of processors) is fairly low (bad convergence behaviour, low robustness, ...)

And then there are "parallelism accross the system" methods. This is where Elastic feels home. Here, the full task is partitioned into multiple of subtasks that are worked on independently over a number of iterative step sweeps. Information is only exchanged at the end of each sweep. This eliminates a lot of the communication overhead. To get back to your use-case: without having too much experience in solving OBEs, my hunch tells me that the waveform relaxation method could fall into this category.

Finally, we can conclude that Elastic will not be the universal toolkit for all problem classes. There are problems that Elastic can solve very good, there are problems that should be solved on FPGAs for the maximum efficiency, there are problems that can only be solved on single core computers and there are problems who need shared memory. It will not be efficient to run a Bitcoin miner on a single CPU core just as it will not be efficient to execute "parallelism across the method" on Elastic.

Great informative answer as always EK!
I think the conclusion is that there is space and justification for a multitude of systems and solutions for the variety of different tasks and use cases.
Elastic can answer some of these use cases very well, while others might be more suitable for different compatible systems.
The rigid premise (some have) of having one main system giving a solution to different needs is just wrong and should be abandoned for a more flexible approach.
Proud to see this project evolving and progressing!

Great, only new Golem as supercomputer. But will for sure also try out Elastic.  Does anyone know the main differences between Elastic and Golem?
