Using Multiple Computers

[vokumus]

Hi STKO Team;

Is it possible to solve models using multiple computers using Prof. Tarque's pack?

Thanks.

It can be done, but you need some experience with it or you need to contact a technician.
Here is a reference on how to build your own small hpc cluster from multiple windows machines

I see. Do you have any suggestions for analyzing large SSI models like with 200-300k elements? While monitoring my system resources, I realized that computer RAM (16GB) is used almost full. Maybe adding more ram may increase the speed?

[STKO Team]

For sure it will speed up. I've seen that I get best performance when I have about 10k elements for each process and at least 1 GB RAM for each process. for a model with 200k elements probably you would need at least 10 processors and like 32 Gb RAM

Thanks for this valuable information.

Hi STKO team,

my model has 107.000 elements.
My PC: 8 cores, 16 threads. AMD Ryzen 7 3800X (3.9 GHz, turbo up to 4.5 GHz). 32gb RAM
I devided the model into 14 partitions.
Earthquake motion includes 4000 steps.

It took around 40 hours to run the analysis.
I am planning to buy a new PC. What should I forcus on? number of cores, CPU speed, or RAM?

Thank for your support.

Actually a combination of them.
The CPU you have already had a good frequency.
You may need more cores.
And about 2 GB RAM per core is a good estimate
