FLOW-3D/MP runs on both Workstations and clusters (which may consist of a group of similarly configured Xeons® or Opterons®) running Redhat Enterprise Linux 6 or 7, a network interconnect such as Gigabit Ethernet or Infiniband, and a large shared NFS disk accessible from all nodes in cluster. FLOW-3D/MP supports Intel® MPI, which is provided as a part of the installation. For hardware recommendations, please contact our sales team.
Support for users who have installed FLOW-3D on “compatible” Linux distributions (such as Fedora, Scientific Linux, Debian, Ubuntu) will only be provided when a problem can be reproduced on Flow Science’s RedHat and Novell enterprise-class Linux distributions.
FLOW-3D/MP requires modern graphics cards with up-to-date OpenGL drivers to perform satisfactorily. At least OpenGL 3.0 support is recommended.
FlowSight works best with graphics cards supporting DirectX 11 or newer. Recommended options are nVidia’s Quadro K series and AMD’s FirePro W series. nVidia’s GTX gaming hardware works with some limitations, such as slow or incorrect functioning of volume rendering.
Integrated graphics such as those commonly found in laptops may be adequate, but discrete graphics capabilities are strongly recommended. At least 512MB of graphics memory is recommended.
Memory and Processor Speed
A minimum of 4GB of RAM is recommended per processor core. For example, a compute node with two 8-core CPUs should have at least 64 gigabytes of memory. Note however that the amount of RAM required is highly problem dependent. For simulations with large domains, or with complex geometry requiring fine resolution, significantly more RAM than the required minimum will be necessary. Memory speed has a small affect on simulation time and typically 1333 or 1600 MHz memory is adequate.
Users who wish to customize any of the subroutines that Flow Science distributes as part of the standard installation will need a license for the Intel Fortran Compiler 2013 and Intel MPI 5.0.
