Flash dryer simulation with ANSYS in the Cloud


Published on

In this one hour free webinar, Team 8 members of the UberCloud CAE Experiment discuss the benefits, challenges, and lessons learned of bringing the end-user’s engineering application to the compute cloud. In this experiment the team worked jointly on a real CFD application – a Flash Dryer Simulation with Hot Gas Used to Evaporate Water from a Solid. Presenters are discussing challenges faced while using Cloud for technical computing and their solutions.

    7. 7.  A leading one-source supplier of equipment and services to the global minerals and cement industries  FLSmidth supplies everything from single machine units to complete minerals and cement flow sheets including associated services  FLSmidth primarily focuses on the following industries: coal, iron ore, fertilizers, copper, gold and cement and has the ambition of being among the leading and preferred suppliers in each of these industries 7 The end-user:
    8. 8. Application  FLSmidth’s largest flash dryer to date is located in Morocco  Dry wet phosphate cake  Hot combustion products mixed with cooler air  Moist solids (21%) added in venturi, ~700tph  Moisture evaporated by hot gas  Remaining moisture content in solids ~6%
    9. 9. Challenges  Computationally expensive, multi-phase, lagrangian, mass-transfer  In-house hardware: Intel Xeon Processor X5667, 12M Cache, 3.06 GHz, 6.40 GT/s, 24 GB Ram  Geometry: 1.4 million cells, 5 species and a time step of 1 millisecond for a total time of 2 seconds  One transient run takes 5 days
    10. 10. Experience  Easy to upload data  Intuitive web interface, Support for extra script commands  Easy run monitoring, using web basedTurboVNC, not so responsive forOpenGL applications  Great support, even when whole cluster went down  1-2 day turnaround  Large amounts of data still need to be transferred
    11. 11. Benefits  Hardware know-how and expense (to some extent) is outsourced  Focus on the results instead of the process  Faster turn around for our application  Useable remote visualisation
    12. 12. Lessons Learned  Positive experience with cloud HPC  Some concerns about remote visualisation  Data transfer at project end need to be considered  Financial analysis still need to be undertaken  Licensing  Our expectations were met
    13. 13.  ANSYS Cloud Services for the UberCloud Experiment  ANSYS Cloud Partner ecosystem provides a flexible set of solutions, with ready-to-goANSYS software running on robust HPC systems  A choice of cloud solutions delivered by ANSYS partners who are experts at enterprise-level HPC, remote hosting and data security  Major Benefits  The UberCloud Experiment is very useful for our customers to explore the end-to-end process of partner-enabled cloud solutions for their simulation workload  Helped to build out ANSYS Cloud Partner ecosystem providing customers with seamless, flexible and secure access to ANSYS simulation and HPC resources 13 UberCloud Experiment : ANSYS’View
    14. 14.  MajorChallenges  Engineering organizations have concerns about placing sensitive data on a 3rd party cloud  End-user productivity in an environment that provides effective remote access to the full simulation process, as well as data and HPC job management  Challenges being solved by UberCloud  Quantify end-user productivity, benchmark application performance, test services provided by the Cloud partner  ANSYS’ recommendation  Join an UberCloud HPC Experiment project with ANSYS! 14 UberCloud Experiment : ANSYS’View
    15. 15. 15 Mix of Business Needs: ANSYS Cloud Scenarios & Licensing Virtual Private Cloud – for “steady” HPC outsourcing •Scaled-up access to HPC needed, but lacking internal IT support/expertise •Potential to centralize resources for multiple sites - collaboration •Goal of lower Total Cost of Ownership (TCO) •Traditional lease or perpetual licensing model Hybrid Cloud – Internal HPC + Cloud for “project peaks” •Short-term, intense project-based demand for more capacity •Fast deployment to respond to unexpected business •Ability to bill to project •Short-term lease licensing model Overdraft Cloud – Optimized asset utilization •Intermittent need for resources that exceed owned assets •Opportunity to optimize spend & asset utilization rate •Usage-based licensing model
    16. 16. Cloud Provider: Bull eXtreme Factory  HPC-as-a-Service bringing scientific apps to the cloud; on Bull’s hardware, web portal and remote visualization technology  Hosted and operated by Bull, comes with an HPC support team, and ready to use applications Bull’s major benefits from the UberCloud Experiment platform  UberCloud Experiment helps creating real world use cases and gives our offers worldwide visibility  Even though the Experiment deals with serious HPC cloud challenges, it is driven in a very friendly and human way.We love how support and collaborative tools help people all over the world working together without ever meeting physically
    17. 17. Cloud Challenges Major Challenges  HPC ISVs are adopting the cloud (licensing) model slowly  HPC customers' purchasing habits are not at all cloud-ready Solving these challenges  HPC market places are demonstrating this is all possible (maybe starting with more open source apps than commercial).  This may help ISVs to take the step. Customers will then adapt/adopt I guess Recommendation to tech computing users : just try !
    18. 18. Team Expert: science + computing  science + computing ag (s+c) www.science-computing.de  s+c provides services and solutions for customers in technical and HPC environments, from system management to app support  s+c supports customers running their applications in their private or external computing environment, integrating them into the customer's workflows and adopting new technologies.  UberCloud benefits to s+c  Gathering experience from real life customer problems  Showcasing examples for potential new customers 18
    19. 19. Team Expert: science + computing  Major challenges with HPC cloud  The process of setting up a customer's application inan HPC-cloud is still quite individual  Data transfer and locality. Suppliers may be constraint by contract to keep OEM's data in house.  Market developments addressing the challenges  Integrated HPCaaS and SaaS and pay-per-use app licensing will make standard HPC-cloud usage easier. HPC-cloud provider should have the flexibility to adopt special customer requirements  Cloud providers in geographical or political "proximity" of the customer  Test the HPC Cloud offerings, see how additional computing capabilities improve products, return results earlier, without the necessity for investment in in-house HPC infrastructure 19
