For "big" units like this, it is generally good to use 1 task using as many threads as you have real cores with Intel CPUs. It can get more complicated on AMD side.

Wait a sec, isn't ice lake only for mobile?

Currently Ice Lake is only on mobile, but server versions are due this year. They could offer HEDT variations at a similar time. I think Intel had said there will be desktop 10nm CPUs this year. No chance on consumer platforms so I suspect they might be talking about HEDT.

I've been seeing rumors of it having super high TDP and a bunch of compute cores or whatever Intel calls it. I'm not optimistic of power consumption for Xe

The parts that were discussed are data centre targeted. They can scale bigger than a typical consumer can tolerate. High power in itself is not a problem providing the overall efficiency is still there. We don't know that yet.

e.g. if you have some task that can scale well to multiple GPUs, instead of two 250W ones, you make one 500W one. It takes twice the power, but as long as it does twice the work, it is ok. If you have racks of GPUs going, fewer more powerful ones will be preferable to many lower power ones of the same efficiency. I think that's what was being shown.

I remain optimistic that Intel Xe will be "good". Maybe not on day 1 but over time. They won a contract for a US supercomputer which is using them heavily, so it will have to work. It is meant to be highly scaleable, so whatever they do should hopefully go up and down the chain.

Now, from our perspective, price, performance, power are all factors that will be unknown for a while...

With luck you'll have time to take some more pictures.

I don't think I'll have much trouble adapting. For about the last year or two, work is something I feel like I have to do, more so than want to do. Things are not constant, and from a personal viewpoint the changes were not for the better. In that sense, redundancy was not feared, but welcome. I wasn't secure enough to just leave, at least not without having something else in place. This gives me more flexibility to consider what form I see my future taking. I will have to cut down on the crunching though.

I do hope to re-take up photography, especially once we're allowed outside more often again.

While not worked out in detail, I estimate I don't need to worry about income for perhaps 2 years without significantly changing expenditure. With any reduction, I can stretch it out a lot more. Thankfully I managed to clear my mortgage last year, so I don't have any significant monthly expenditure. I might cancel some less important subscriptions and downgrade my broadband later.

Food is certainly a big area I could improve on. Even now, I still rely largely on ready meals and deliveries, but I know I can cook much healthier and cheaper. Time to do so will not be a limit going forwards.

Today is packing up work property from my temporary home office, which I will drop off next week to close the last loose ends.

Crun-chi hope things work out one way or other.

Today is also a major milestone for me, as it was the last working day in my job of over 22 years. This was agreed before the virus impact and I don't have to worry about getting a new job in the short term. Still, it is as big a change to my life as starting to work itself. No plans as such yet...

I have to admit I've been slacking a bit on this one as a balance between heat and noise, and being stuck at home with it! Still now the work week is over I've dug out the Skylake-X and got it going again for the last stretch.

I loved the Rosette as a target to try for when it got a bit late for Orion. Looks like you got more detail, especially of the dust, than I ever managed.

Try Prime95, but I don't have the details of how to do it right now, mackerel (I think) does.
Process at above link. FFT size to use for SGS is 128k.

I debated if I should, but did spend the weekend away with friends, with their explicit ok we could go ahead. Just got home to hear the lockdown has been ordered in UK.

My plan was to go to the shops tomorrow... if there's still anything left. I might have to practice my unarmed combat skills before going, although my gout will hold me back. I feel old, but nowhere near enough to get the early access.

More seriously, I wont starve with what I have at home, but it's all food I didn't want to eat previously. Need some fresh stuff to go with it...
