Installing nek5000 V19 or V20?

[Nadeem Malik]

Hello neks,

I am trying to install nek5000 on a new machine (Johns Hopkins Rockfish), and I want to know what is the latest fully validated version to install. I have been using v19 till now, but is v20 now recommended?

What are the main differences between v19 and v20.

I also want to install the latest ppiclF subroutine.

This is what I have been recommended so far -- but I do not see a choice for the different versions of nek5000 or for ppiclF? Can you advise, thanks:

cd ~

git clone https://github.com/dpzwick/ppiclF.git            # clone ppiclF

git clone https://github.com/Nek5000/Nek5000.git           # clone Nek5000

mkdir TestCase                                             # make test directory

cd TestCase

cp -r ../ppiclF/examples/Nek5000/* .                       # copy example files to test case

cd ../ppiclF                                               # go to ppiclF code

cp ../TestCase/user_routines/* source/                     # copy ppiclf_user.f and PPICLF_USER.h to source

make                                                       # build ppiclF

cd ../TestCase

./makenek uniform                                          # build Nek5000 and link with ppiclF

echo uniform > SESSION.NAME && echo `pwd`/ >> SESSION.NAME # create Nek5000 necessary file

mpirun -np 4 nek5000                                       # run case with 4 processors
