Memory error: Falcon Moose #16878
-
Hello Everyone, I am trying to run a big mesh (4Million cells) simulation using Falcon/Kerstel (MOOSE) on Sawtooth (at INL HPC) but the simulation keeps crashing. The errors and number of processors used are listed below. I have tried running the simulation in multiple combinations for the number of processors requested/used: Error 1: Building mesh .......................... [ 27.39 s] Running App: main Framework Information: Parallelism: Mesh: Nonlinear System: Auxiliary System: Execution Information: LEGACY MODES ENABLED: Caching mesh information .... [ 5.33 s] Error 2: Computing initial residual ..... [ 6.09 s] ===================================================================================

Hi Pranay You should request a number of nodes directly, and specify the maximum amount of memory available per node. Guillaume |

Hi Pranay
You should request a number of nodes directly, and specify the maximum amount of memory available per node.
Can you paste your PBS script here? The part where you are requesting ressources especially.
