comcot (gfortran)

• I've made comcot compatiable to gfortran since I started the GPU-comcot project. However, the original comcot, which runs on CPU serially, did not remain on my git history. Besides, I've heard of demands on gfortran compatiable comcot recently and it takes quite some efforts to transfer from ifort to gfortran for beginer who's not familiar with fortran. Therefore, I made this repo to respond the needs and make it as a benchmark to be able to test the speedup against GPU-comcot.

Requirements

software

(possible supported version/developing environment):

• gfortran (4.1.2-46 ~ 8.2.0/4.8)

• GNU make (/3.82)

Notes: Platforms other than Linux

MacOS

• gfortran compiler can be equipped with gcc at version 8. Therefore, the easiest way to install gcc is by brew install command , then you will have gfortran ready. Or reference the GNU site to build gcc by several of ways other than brew. Here is the link instructing how to build precompiled gcc binary package for MacOS.

Windows

• Precompiled gcc

Installation

clone

git clone https://github.com/HandsomeAndy/comcot-gfortran.git

Setup

GNU solftwares

• Generally, gnu make and gfortran are pre-installed on linux machines. Try make --version and gfortran --version to check if they exist. See 'Notes' for more informations.

Install

make

Run a Simulation

• The input file of COMCOT is called comcot.ctl. Modify the file to specify a simulation time, time step, fault parameters, and grid settings. Additionally, a corresponding topographic file (available at etopo) is required for grid construction, and the path to the file should be provided in comcot.ctl. For example, the fresh downloaded comcot.ctl takes ../etopo_halk2.xyz as the topographic file and simulate the 2011 Tōhoku tsunami.

• To run the simulation, simply execute the program comcot

./comcot

gfortran compatible version of COMCOT was developed by Tao, Chiu at Tsunami reseach group, IHOS, NCU. The goal of this work is to librate, coporate ideas with the community and accelerate the development of a high-throughput tsunami warning system at a relatively low cost. Original COMCOT version can be found at here.
