The current set of jobs that I have ready to go (in fact, I was running them during the EU period), have meshes partitioned for 4096 cores. So, they can be run either on 128x32 cores on (BDW) or 64x64 cores (on KNL) although the KNL would take a longer wall clock time. For my runs, I can do a 25% (BDW) 75%(KNL) split, since there are ways to accelerate the solution on the KNL nodes. ----------------------------------------- Ray Bair Argonne National Laboratory and the University of Chicago From: "Pieper, Steven C." <[email protected]<mailto:[email protected]>> Organization: Physics, Argonne National Laboratory Reply-To: "Pieper, Steven C." <[email protected]<mailto:[email protected]>> Date: Wednesday, August 30, 2017 at 11:08 AM To: Raymond Bair <[email protected]<mailto:[email protected]>> Subject: Re: [LCRC alloc-com] Request for interim 3DDES project allocation of 1M core hours on Bebop I guess OK although it is ~1/16 of the total Broadwell hours available for Sept.

I have submitted a project request for an allocation that I understand will start from October 1, 2017 (if the proposal is accepted). If possible, please grant me 1 TB of project space for this short term allocation of 1M core hours for the same project name, i.e. 3DDES. Do let me know if you have any questions.

Hello, A new project on the LCRC cluster has been requested. Please forward the information on to the LCRC Allocation sub-committee. Applicant's name: Ramesh Balakrishnan Applicant's institution: ANL Applicant's division: LCF Project Name: 3DDES Project title: Detached Eddy Simulation of Separated High Reynolds Number Flows Associated funding: ASCR Funding via ALCF Other Systems: Theta, Mira, Bebop Science: I am requesting 10M core hours, for the whole year, on Bebop, to develop detached eddy simulation models that can serve as a wall model for moderately separated flow in thick boundary layers. Examples of such flow are the atmospheric boundary layer (ABL) over complex terrain, large eddy breakup devices (LEBU), and separated flow past airfoils at high angles of attack (i.e. greater than 10 degrees). Project description: Preliminary simulations of the ABL over Complex Terrain have been carried out on Bebop during the Early User Period, where the PI had an opportunity to run and test out modified version(s) of OpenFOAM, SU2, and FDL3DI on Bebop. The simulations were run on meshes ranging from 28M grid points to 140M grid points, and on a maximum of 4096 cores of Bebop. The codes make use of MPI and can optionally use OpenMP. In addition, one can vectorize the code for the KNL nodes (in which case OpenMP is not needed at all). During the early user period, the vectorization and OpenMP options were not tested out. The flat MPI codes do scale well on both the KNL and Broadwell nodes, although the time-to-solution is about five to six times slower on the KNL nodes (when compared to the Broadwell nodes). This is something that I plan to investigate in more detail as part of this allocation request. Industry partnership: None at this time.
