  • Army Corps work set to resume on Fire Island, NY & Monmouth County, NJ Coastal Storm Risk Reduction Projects

    The B.E. LINDHOLM arrived at Fire Island on May 6 and is completing final preparations to begin work, while the MAGDALEN will arrive on or about May 15. B.E. LINDHOLM is expected to begin work on the Point O' Woods and Ocean Bay Park portions of the Fire Island Inlet to Moriches Inlet Coastal Storm Risk Reduction Project (FIMI).

  • PUBLICATION NOTICE: Using Morton Codes to Partition Faceted Geometry: An Architecture for Terabyte-Scale Geometry Models

    Abstract: The Virtual Environment for Sensor Performance Assessment (VESPA) project requires enormous, high-fidelity landscape models to generate synthetic sensor imagery with little to no artificial artifacts. These high-fidelity landscapes require a memory footprint substantially larger than a single High Performance Computer’s (HPC) compute node’s local memory. Processing geometries this size requires distributing the geometry over multiple compute nodes instead of including a full copy in each compute node, the common approach in parallel modeling applications. To process these geometric models in parallel memory on a high-performance computing system, the Geometry Engine component of the VESPA project includes an architecture for partitioning the geometry spatially using Morton codes and MPI (Message Passing Interface) collective communication routines. The methods used for this partitioning process will be addressed in this report. Incorporating this distributed architecture into the Geometry Engine provides the capability to distribute and perform parallel ray casting on landscape geometries over a Terabyte in size. Test case timings demonstrate scalable speedups as the number of processes are increased on an HPC machine.

  • New Lock at the Soo construction set to begin

    The U.S. Army Corps of Engineers, Detroit District, announces that the New Lock at the Soo project is on schedule as construction for phase one of the project began this week. Trade West Construction, Inc., began to move equipment to the site on May 4 and will begin deepening the upstream approach to the locks in the north canal within the next month. Phase one of the project, upstream channel deepening, will facilitate the construction of a new Poe-sized lock in the place of the existing Davis and Sabin Locks. This work is expected to be complete in November 2021. “It's incredible that we're starting this construction a year earlier than even the most optimistic projections when the project was reauthorized in 2018,” said Lt. Col. Gregory Turner, commander, USACE, Detroit District. “Getting the first phase started sets the conditions for the project’s ultimate completion.”

  • Corps of Engineers Extends Closures on Campgrounds and Shelters in West Virginia, Kentucky, Ohio, and Virginia

    HUNTINGTON, W.Va. – The U.S. Army Corps of Engineers, Huntington District, is extending the closure of Corps managed campgrounds and group shelters within the states of Kentucky, Ohio, and Virginia in the interest of public safety due to the COVID-19 pandemic. In Ohio and Kentucky, the closure is extended through May 31, 2020. In Virginia, the closure is extended through June 10, 2020. In West Virginia, a final decision is expected on campground and shelter schedules by May 12, 2020. While an official date for reopening has not yet been determined, all campground and group shelter reservations will be canceled thru the dates listed above. All customer reservations affected will receive a full refund.
