Intel launches new 28-core Xeon CPU

Yup, I’ve never heard of anything close in SA. Some GPU courses, but even those were somewhat basic.

Doing real HPC is highly in demand. Think of how beneficial it is if you can get results 10x faster or use 10x less resources on a $50m supercomputer.

I seriously need to refresh on my C coding, that's for sure...

Heh. Using BLAS?

Yep, some. ARCHER supports Fortran, C, C++ and Python. Because my C is really rusty I've been using Python, but it seems to be literally 100 slower for my purposes than C equivalent code, so although the easiest for me, Python probably isn't the best choice.

We use python as our “glue” code and C/C++ for everything else on our supercomputer. We are careful to “not do any real work” in Python, but the number of times we’be found the glue code run-time get out of control has been surprising.

“It’s just doing a simple accumulation pass through a file, surely it will be IO limited”
“...nope”

Interesting. I'll keep that in mind. It's still early days so I'll probably start running into examples like that only sometime in the future, and even then it'll only be academic in nature, until I emigrate and find an employer who is actually using this tech.

You need to define 'best product' as it could mean most expensive with best performance. Value, power consumption, heat output, security, performance etc are all factors in 'best product'. Since I'm sure most applications of this CPU will be commercial, I think most buyers will actually look very carefully at all these factors and ensure they've made the right decision.

Saying that you 'just' buy the 'best product' is like saying you just pop in the corner shop and get some milk. This CPU will in most applications be an asset part of some infrastructure or system working to recover the capex cost, most buyers will think very carefully before buying this - especially with AMD being so aggressive in this market space.

Just read up what first gen Threadripper/Zen did to this market, Intel changed their whole strategy because of AMD since then.

I said

best product for your use case

there is nothing about brand loyalty in my post. When push comes to shove the best product is defined by ones requirements not by ones loyalty towards one brand or another.
