Honestly, I'm not even sure how much a review would help either. I struggled quite a bit with linear algebra in school with Curtis' Abstract Linear Algebra , and eventually I decided to hole up in the math library for the better

I agree with tanderson92. Whether the actual science from all the simulations is "worthwhile" is for people much smarter than me, but to get time on a "leadership" class machine, you have to prove in your application tha

I worked on a system that was at one time #3 on the list. There were no substantial idle periods. If the machine was out of maintenance, jobs were being run on it. Depending on the internal structure of the machine, some parts of it might b

At least in my schooling, Upton Sinclair was held up as the very model of a muckraker, and he was certainly anything but (2) above. Perhaps sensationalist on occasion, but strongly principled.

Gotcha. Sorry to have kept to conclusion; thanks for the clarification.

I'm not even sure where to start with this. I went to a fancypants-ish school in the University of Chicago which does not have a Harvard or Yale-sized endowment so they likely did care about tuition. We did indeed have a lot of Chinese

Do you have any citations for this? I'm extremely skeptical. Harvard doesn't need the $20M; they're doing just fine as it is.

I have no relevant experience in academic finance, but I sincerely doubt it. The brand and reputation of the universities are what allows them to charge so much for tuition and get prestigious faculty (i.e. grant money). Besides, at a large

I'm sorry, but I have absolutely no idea what you're trying to say. Would you mind providing an alternate phrasing for your comment?

The old Cray-1s certainly are iconic and beautiful machines. Just from my personal experience working in HPC for the last 15-20 years, what I think is driving us away from these cool old-school designs (Thinking Machines were always my favo

This is a subject near and dear to my heart, albeit from the "enterprise" side of the table, not the scrappy startup side. I've spent a non-trivial amount of effort trying to convince software companies to spin an on-premise

This is precisely what I was going to respond with. I "manage" a technical group of 27, and we have people that run the entire stretch between one guy I check in with every 4 hours, and another guy I talk with once a month to make

To me (who, to be fair, has no experience in this area), it seems that the only long term solution to this liability issue is a government-funded and controlled fund accompanied by legal changes prohibiting these cases from going to "n

I really don't see even the remotest of relevance of said test to the situation at hand. Airplanes do exist, they carry millions of people a day, and governments must issue and enforce regulations to ensure their safety. It doesn'

I'm not sure what the benefit of encryption there is anyway. Governments have a very effective way of decrypting stuff like this: getting a court order to hold employees in prison until the data are decrypted. Maybe they have no actual

Your point in general that public pension funds have investigated in riskier assets over time is correct, but your claim that the 2008 crisis had any significant uptick after the 2008 crisis is quite simply false. Honestly, to make a claim

This will be a 10x improvement in the 6 years since Titan was built and will get within nearly 20% of an exaflop. How does this not constitute a huge step toward exascale computing?

That doesn't surprise me at all. The DOE keeps more options open by selecting different vendors for the same generation installs. In the last generation, LLNL and ANL were IBM and ORNL was the Cray. That said, I'm long since out o

Having worked at ANL in the past on other supercomputers, this is an especially impressive and interesting contract. 180PF, even in 2018 is by any definition an absolute monster of a system. It's also very interesting that the contract

I'm torn on this. I've spent nearly the last 20 years in some form or another in academic/research computing. On the one hand, attitudes like the third reviewer's are a primary reason for the state of HPC today, where ne

There are probably other reasons, but the NVLink interconnect is expected to show up on Power systems long before Intel, putting the GPUs much, much closer to system CPU and memory. This thing is going to be a beast.
