HPC Trial: Test Project
Original work was to simulate the dispersion of natural gas from leaks occurring within a ventilated gas turbine enclosure.
Work part of an assessment to ensure compliance with Health and Safety Executive regulations.

HP Workstation xw8600 Xeon E5405 CPU, 2 cores
4.5M elements meshing Steady state, complex geometry, simple physics 340 iterations, around 24 hours to complete More than 10 simulations requested for the work
HPC Trial: Outcome
The HPC Trial reviewed a range of configurations:
Simulations with 24 to 128 CPU cores.
6 different meshes used from 4.5 to 80 million cells.
Normalised results for 2010 this gives an equivalent time of 5240 sec.
HPC speeds-up from 30 to 145 times the 2010 values.

Biggest advantage of the HPC is likely to be for jobs that:
Have large parameter spaces.
Are time dependent.
Have complex geometry.
Have very complex physics.
A combination of the above.
