At the moment, BASEMENT does not support running a single simulation on multiple GPUs, so there is no additional YAML or simulation.json setting for this.

GPU memory usage is determined by the problem size and enabled features, such as the number of mesh cells and sediment grain classes. Having more GPU memory available than the simulation requires will therefore not improve performance. Similarly, GPU utilization may remain below 100% depending on the model setup and computational workload.

Anyone could suggest any rent remote CPU time services for BASEMENT simulation?

Thanks!

The topics/threats here already exist for some years which is alot if you look at the CPU development.

I wonder if there are any newer experiences with BASEMENT on the newer AMD plattform (EPYC or even Threatripper...).
If someone wants to start using BASEMENT and builds its own computer - the question comes up: where to put the money :-)

Are the recommendations still "two cpu sockets each 8 cores with a clock >= 3ghz"?

For example the AMD Threatripper with 4 RAM modules seems to have also a good speed cpu<->ram....

Another example, both of the server cpus meet the recommendations:
Xeon gold 6134 3.2 GHz, 8 cores, memory speed 2666mhz
EPYC 7262 3.2 GHz, 8 cores, memory speed 3200mhz
Are the two cpus both more or less "good"? anyone who can tell us more..?

And the other question for starters: Linux or Windows? The use of GPU seems to be supported only on linux - for now...
Is the performance more or less the same (when GPU support is also in the windows version)... ?

Maybe I care to much and a really good  desktop (gamer) configuration will do it also???

Thank you for any recommendation or advice

- I tried assigning everything from 1 to 0 threads (0 apparently uses all available cores = 24 with hyperthreading) with the same result and awkwardly slow computation performance and RTS
- I tried v2.4, v2.5, v2.6 and v2.7 - same story throughout

Maybe the attached screenshot illustrates my dilemma.
Does anyone know what could be the issue?

Thanks in advance.

I did a quick google search on your processor and it seems that your processor "only" has two cores. Using more than 2 cores in parallel mode wouldn't save time or could even increase the computational time (my experience).
A bit more information on parallel computing with BASEMENT can be found here:

You could create a coarser mesh and only refine the areas of interest.

sorry, I have just found out the problem wasn't connected to Windows 8 but to an hardware component of my laptop.

Now it works very well also with Windows 8.

MOTHERBOARD:
We recommend the use of motherboards with 2 cpu sockets, i.e. 2 x 8 core.

CPUS:
We recommend the use of cpus with maximum 8 cores and high frequency, e.g. 3 GHz.

Of course, you can use motherboards with 4 or more sockets and cpus with more than 8 cores. However, the problem is the memory bandwidth, that does not scale either with number of cores nor sockets. Thus, be careful before spending a lot of money to end up with a inefficient system.
