Different speeds in different systems

Open hosseinrezaa opened this issue 4 years ago • 2 comments

Hi I am using CPU simulation of a model to simulate in SPLISHSPLASHin two different systems. Everything is similar and we are using CPU simulation not GPU. The question is that the powerful system is slower.

The weaker system is faster

Is there anything that should be adjusted in the powerful system?

the weaker system is a pc that I am using and the more powerful system is a workstation that I connect using a remote desktop and run the program

Performance tests with just 125 particles are misleading. Then the overhead for the parallelization is higher than the benefit. Try to test this with more particles, e.g. 1 million particles. Then you should see clearly a difference.
