[Users] questions about compilation

[Joel Giedt]

Hi, I struggled for days trying to get ET installed on Stampede2 (no
problems on Stampede1, so some issue about the different environment, which
is supposed to be KNL oriented).  It worked 100% with very little
intervention on my part for Bridges, compiling in about an hour.  On
Stampede2, after some suggestions from various people I managed to get all
the object files and libraries built for all the thorns, but then it didn't
like a couple of the arguments being passed to ld, which are hard to fix
because it's not at all obvious how to modify the make-cycle.  I could go
into all the details of snags I hit for anyone who is interested. Anyways,
as Roland suggests, trying a different resource might be a very good idea
because the process seems rather sensitive the local environment. --Joel

Hello Chia Hui,

sorry for the long delay, I got caught up with Christmas preparations.

No I do not think that it took so long to compile on edison before. I am
tempted to see if using the gnu compiler would be any faster. This is right
now so painfully slow as to render the system almost unusable.
it also does not help if one tries to compile in /dev/shm or from within an
interactive job so the "usual" remedies for slow compilation do not apply.

If you want to use a different cluster then I would try and start from the
files for a similar, working one. Eg for Cray machines the bluewaters-gnu
files are a good starting point or maybe the cori ones (it being a newer
cray).

We have a wiki page: 

https://docs.einsteintoolkit.org/et-docs/Configuring_a_new_machine

that describes the procedure and would be happy to help out on the mailing
list (or on the system if one of us has an account there).

Yours,
Roland
