Progress Update 10/9/2021

We outlined the simulations in the project description “Solar Jets”

All the simulations and models are detailed on git hub these are the smaug_jet@github

Created branch in smaug_jet project for the MPI developments smaug_jet_mpi
Initial testing of jacobi-bede a cuda enabled MPI example cuda examples in smaug_jet_mpi
Main branch of smaug_jet used for single GPU testing and model runs smaug_jet

NVIVO is helpful for annotating papers and for coding. As a guide to tracking data each directory on the compute systems will have a file list. A data folder in the git repo will contain subdirectories corresponding to each of the systems used. Each subdirectory will have a directory contents txt file detailing the data. These may be coded as external files within NVIVO.

Preparation of point source model

source term checked Driver source file
include file checked Model include file
config file checked
driver script ready

Need to check the following

boundary term
data output location on bede (see bede docs. )

Comments about compilation flags and compiler selection

openmpi/ucx is known to be buggy when doing MPI one-sided operations. Cliff seemed to have better luck if he added the “–map-by ppr:2:socket” flag.

If that flag helps, can you give admin more details about what you are doing?

e.g. job script

Alternatively, building against the MPI in module mvapich2/2.3.5-2 works much better in this situation.

Rendering examples

Note use %2B to represent +

$e^{i +\pi} =x+1$

LaTeX

$x_{1,2} = {-b\pm\sqrt{b^2 - 4ac} \over 2a}.$

This math is inline $a^2+b^2=c^2$.

This is on a separate line

a^2+b^2=c^2
