In Core Out Core Min Core

Altair Forum User

Hello,

 

I want to ask if someone know what is the difference between In-Core, Out-Core, Min-Core.

I've seen this in optistruct option.

In-core means that the solver can hold the entire data (matrix K if you run a static analysis) in the RAM.

 

Out-core means that the solver can't use the RAM to store the data. The solver will store all the matrices in the disk. The resolution will be done using the RAM and in the end, we will write the entire data in the storage disk.

just adding a few comments.

 

RAM memory is much faster to access that storage disk. So running 'in-core' will bring a significant speed-up compared to out-of-core runs. Of coarse, your machine needs to have the amount recommended to take advantage.

Hello Sir,

I want to ask that how we can change the setting between incore and outcore solution in hyperwork.

What I mean is where I found that option to change the core

on options line in Altair Compute Console when you submit the job, use option '-core in'

(or '-core out')
