Dear Roland,<br>
<br>
thank you for gathering these links, they are indeed useful to point me in the right direction.<br>
<br>
I also found this seminar talk by Erik Schnetter on using Spack to install the ET dependencies.<br>
I also copy it in this thread, so that it is grouped with the other resources you gathered:<br>
<br>

<br>
I will work my way through this material and let you know if I encounter other problems.<br>
<br>
Best,<br>
Panagiotis<br>

Hello Panagiotis,<br>
<br>
Thank you for your inquiry.<br>
<br>
This may help:<br>

There's also some advanced simulation factory docs here:<br>

<br>
See above. Spack is tricky and often does not work out of the box<br>
unless one really builds everything from scratch. Some of the ET users<br>
have experience and they may be able to provide help.<br>

<br>
The recording of the seminar (and the slides therein) tries to do that.<br>
I would give it a try.<br>

<br>
Unfortunately each cluster is different and often one needs specific<br>
detailed workarounds. A lot of that unfortuntely comes down to<br>
experience.<br>
<br>

<br>
I'd start with an existing cluster that uses the same compiler / queuing<br>
system. Queueing system these days should always be SLURM and one can<br>
then try and see if the cluster supports the GNU compilers which should<br>
make things easy.<br>
<br>
The only libraries that one really needs from the cluster are MPI.<br>
Everything else can be built by the EinsteinToolkit if needed (by<br>
setting the various FOO_DIR variable to the string BUILD).<br>

<br>
There is no real good docs unfortunately. Even the ones that I had<br>
linked above are (were, they are now) not collected in a single place.<br>
<br>

<br>
Bruno Giacommazzo installed the ET on some of the CINECA clusters in the<br>
past. I would try and reach out to him and his group at Milan. The<br>
newest machine still in simfactory is marconiA3 which however is<br>
already quite old. He also is subscribed to this mailing list.<br>
<br>
Yours,<br>
