Solver for meshing

Hi

 

I was wondering which of the following should be used as a Solver:

 

1) My mchine : 16 GB, 4 cores

2) Cluster : 64 GB, 16 cores

 

Is there any advantage of using cluster as a Solver, as there is in terms of solving?

 

Regards

This can be a difficult question as times with the given unknowns.

 

Making a few assumptions:
If both local machine and cluster have the same clockspeed per core (X Ghz), and the Cluster is setup with appropriate interconnects (Infiniband [10Gbps+], not Gig-e ) then the Cluster would be a faster solver.

 

Outside of that, it can depend on the above mentioned factors if the Cluster would be faster or not.

Cluster: 4 boxes, each with 4 cores of 3.4 GhZ and 16 GB RAM, connected by Infiniband SDR 4X using RDMA, 10 Gbits/s, latency ~5 microseconds; totalling 16 physical cores and 64 GB RAM

 

My machine: 4 cores with 3.4 GHz, 16 GB RAM

 

Connection speed of intranet in company: 1 Gbits/s

 

Given this, would 16 cores or even 8 cores of cluster be sufficiently faster than my machine?

Based on what you wrote I would expect the cluster would be faster.
