Why 10x More HPC Matters?

hpc scalibilityIn my talks with engineering managers, flow analysts and IT staff, I often hear variants of this question. Why is more computing power a strategic asset for my engineering department? Why does scalability matter for my simulation jobs that don’t go beyond 32–64 cores in parallel? What’s in it for IT when we are stuck with our current HPC server or cluster for at least two years? Let me try to answer each of these questions.

At a very high-level, a recent survey report from the Council on Competitiveness reports that two-thirds of US companies that use HPC say that “increasing performance of computational models is a matter of competitive survival”. Sixty percent of US industry representatives surveyed claim their most demanding HPC applications could utilize 10-fold increases in computing capability over the next five years.The report also cited software scalability as the most significant limiting factor in reaching 10x improvement.

The demand for scalability is driven not only by existing application needs but also by new application requirements. Fifty-six percent of the same surveyed respondents said that new applications in the development queue will require significant increases in scalability.

For example, in Fluent we’ve implemented optimized algorithms for sliding interface intersections and load balancing that result in a 55 percent speed up (with respect to Release 16.0) on 384 cores for a 1.6 million cell internal combustion engine (ICE) simulation. Thanks to multiple improvements made in discretization and linear solvers, a full transient hydroturbine simulation using 512 cores and an internal turbulent flow simulation using 4,096 cores with ANSYS CFX both show time savings of up to 30 percent (again with respect to ANSYS 16.0).

  2. Hello

    This is HAMDI, I am a researcher at SeoulTech University – Korea

    I would like to say thank you for the academic contribution that it made providing highly valuable information and details

    I have just a question and I will highly appreciate if you help me with

    I am using ANSYS-CFX to model a radial inflow turbine,

    In the section of Materiel Specification, I have used a RGP file (Real Gas Property) instead of a Real Fluid Equation of State to model my fluid

    When I run the solver on Linux, I got an error message saying that the system could not open and read the RGP file, but when I run it on Windows I got a result.

    I would like to know why the Linux could not read the RGP file and fail to solve the problem

    (| ERROR #001100279 has occurred in subroutine ErrAction. | | Message: | | Stopped in routine SU_PROPS_RGP |)

    Answering on the above would be highly appreciated

    I hope to hear from you soon

    Thank you

    Kind regards


    • Hi Hamdi, I’m sorry but we are able to give technical support on the blog. You might join the LinkedIn ANSYS Users Group and ask your question to the community.
