Having run into this at a smaller scale for one of the projects I ended up using devtoolset-6 (and -7 as appropriate) that ships all this stuff such as newer GCC, GLIBC, etc. Me too, I ran the 4.x kernels from elrepo on EL6 and EL7 for newer NVIDIA drivers as well...

Re: Who Uses Scientific Linux, and How/Why?
In the Gina Cody School of Engineering and Computer Science, at Concordia University, Montreal, we've been using SL since around SL5 for our 100+ servers, 1000+ lab desktops (dual boot), and recent HPC facility Speed (concordia.ca/ginacody/aits/speed) loaded with all kind of engineering and parallel processing packages and stuff for deeplearning, etc. -- the packages are compiled on an NFS-mounted software partition at all locations. Why? Primarily because SL was championed by Fermilab and CERN and provided support for minor version releases unlike CentOS. And we've been a RH shop in the past for all of our infrastructure for a long time. SL was the best stable option compared to the alternatives back then and CentOS faced uncertainty. We tried Fedora in the past for the desktops, but maintaining that many lab desktops every semester from bleeding edge updates breaking stuff too often, forced us to move desktops off Fedora to SL as well. Still using it all today, but for EL8 we will be something of an adventure I guess at some point in the future. -s On Mon, Feb 24, 2020 at 9:09 AM Peter Willis wrote: > > Hello, > > > > The variation in uses of t Scientific Linux is quite interesting. > > As mentioned before, we are using it for fluid dynamics modelling and > oceanography, in the context of parallel computing with OpenMP and MPICH. > > > > I am curious to see what everyone else have been using it for. > > > > Perhaps, if it’s not too much trouble, people on the list might give a short > blurb about how they use it and why. > > Maybe also mention others they know who are using it who are not on this list. > > > > Peter > > > > > > > > >I'm no scientist, just an electronics guy who do a lot of research in RF (as > >hobby, mostly testing antennas for ham radio in VHF bands) from Argentina. > > > > > >Fot SL the most "well done" linux distribution, for people who simply knows. > > > > > >Will look forward to move to another distribution. > > > > > > > > >>I'm an independent electronics inventor, heavily dependent > >>on both competent software and competent laboratory science, > >>both for the knowledge I depend on and the tools I use to > >>transform that knowledge into products and services for > >>my customers. > >> -- Serguei Mokhov https://urldefense.proofpoint.com/v2/url?u=http-3A__www.cs.concordia.ca_-7Emokhov=DwIFaQ=gRgGjJ3BkIsb5y6s49QqsA=gd8BzeSQcySVxr0gDWSEbN-P-pgDXkdyCtaMqdCgPPdW1cyL5RIpaIYrCn8C5x2A=ReXrKueW8ZKy6ZeDrhbuU0jFxocBkwAtzvgZ8Lw2ARo=be7he2wCrlv4hIwX_h0scVYIki4Qb7seECAg7OOc-MY= https://urldefense.proofpoint.com/v2/url?u=http-3A__cciff.ca=DwIFaQ=gRgGjJ3BkIsb5y6s49QqsA=gd8BzeSQcySVxr0gDWSEbN-P-pgDXkdyCtaMqdCgPPdW1cyL5RIpaIYrCn8C5x2A=ReXrKueW8ZKy6ZeDrhbuU0jFxocBkwAtzvgZ8Lw2ARo=r1CyWyPBkhOKlYHXLLBrBRzhyvOXZfdHagfuQ1DQWDk= | https://urldefense.proofpoint.com/v2/url?u=http-3A__mdreams-2Dstage.com=DwIFaQ=gRgGjJ3BkIsb5y6s49QqsA=gd8BzeSQcySVxr0gDWSEbN-P-pgDXkdyCtaMqdCgPPdW1cyL5RIpaIYrCn8C5x2A=ReXrKueW8ZKy6ZeDrhbuU0jFxocBkwAtzvgZ8Lw2ARo=GqE1OMX9RmXnxHlwLxQhCFqwgZdIh5nqA-PoNF1J30c= https://urldefense.proofpoint.com/v2/url?u=http-3A__marf.sf.net=DwIFaQ=gRgGjJ3BkIsb5y6s49QqsA=gd8BzeSQcySVxr0gDWSEbN-P-pgDXkdyCtaMqdCgPPdW1cyL5RIpaIYrCn8C5x2A=ReXrKueW8ZKy6ZeDrhbuU0jFxocBkwAtzvgZ8Lw2ARo=AChVu3ppzcRMQhwedztVKVDCZpdn7eviggK3B8gom7Y= | https://urldefense.proofpoint.com/v2/url?u=http-3A__sf.net_projects_marf=DwIFaQ=gRgGjJ3BkIsb5y6s49QqsA=gd8BzeSQcySVxr0gDWSEbN-P-pgDXkdyCtaMqdCgPPdW1cyL5RIpaIYrCn8C5x2A=ReXrKueW8ZKy6ZeDrhbuU0jFxocBkwAtzvgZ8Lw2ARo=lBCv7stSS6iCundVO4eoQ9BsgR8UV294lSmdDozJ8Q8=

I used LaTeX and Inkscape for most of my drawings in my doctorate dissertation. Though I did not use much of the built-in LaTeX integration within Inkscape itself, for my documents I exported drawings as .png or .pdf for better quality and used them as figure environments. Inkscape is a good portable tool for such things.
