  • Previously this work has been performed on a HP xw8600 Workstation with Xeon E5405 processors. In that case the mesh consisted of 4536737 elements and was run in parallel on 2 cores. The time to complete 340 iterations was 23 hours, 13 minutes and 28 seconds (CPU core and Wall timings were almost identical). Given that 10 or more such simulations for different leak locations are required then the assessment of the GT enclosure can take several weeks to complete.
  • We ran the gas turbine simulation with a number of different parameter sets ranging from a 4.5m cell mesh on 24 cores, through to an 80m cell mesh on 128 cores, and observed speed-ups of betwen 30 and 145 times the performance of the in-house system based on workstation class PCs.HPC cores are more than twice as fast as the 2010 cores. For HPC Grid 1 case the speed-up should be 12 (2 cores compared to 24) but it was actually 30More cores gives reduced turn-around time, for example from 10 days to 1 day, with much improved resolution

    8. 8. 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 work8
    9. 9. 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. Grid 1 4.5M elements 24 cores 2010 Figure – 5240 sec Grid 2 8M elements 48 cores The lower this number the better Grid 3 15M elements 48 cores Grid 4 25M elements 60 cores Grid 5 45M elements 128 cores Grid 6 80M elements 128 cores9
    10. 10. HPC for what? Non-linear models Biggest advantage of the HPC is likely to be for jobs that:  Have large parameter spaces.  Are time dependent.Power  Have complex geometry.  Have very complex physics. Partnership Linear models  A combination of the above. Solution Desktop Small cluster HPC 10
