I can't think where that's been R'd from. If anyone cared, 500000 years or so seems quite old.

Changing the title makes it sound as if 2000-year old human remains are somehow rare in the British Isles. I don't think even obviously murdered ones are that exceptional.

And so aphyr gets paid, for instance. You may not even be able realistically to run a test case. The laws of life say your 10000 core compute job will fail non-deterministically only after a day or so. It would clearly be helpful to have a

There would be something amiss if it was vectorizing at O1, and if it was disregarding arithmetic rules (as the Intel compiler would by default).

That's interesting, and I should have a closer look later, being long out of following GCC optimizations; I'm not good with assembler and never remember how the dumps work. The interaction between unroll-and-jam and unroll is conf
876.
by gnufx 6y ago
Note that the code GCC generates for reductions (dot product, anyhow) will not be scalar with an option like -Ofast. That enables loop vectorization but also use of non-standard-conforming SIMD for the non-associative operations. It likely

Surely you'd have some sort of remote KVM in such cases (like IPMI, as mentioned in another comment). That's critical in the clusters I've run and, of course, the manufacturers' implementation of that critical function

How do you record the key used from that (assuming that's what's required)?

I don't know what it looks like for a certificated system, but syslog records the private key used for login in a fairly vanilla Debian. If you worry about things like that and aren't looking at physical access (as suggested else

Even the OS data -- at least what I can see in Aurora -- might not be as complete as where someone has taken an interest in a new development, such as one near here. The OpenData building shapes are a good start, but they appear to have be

Whether buildings are mapped, and in what detail, just depends on the area; detailed mapping definitely isn't confined to London. The main utility of mapping buildings for navigation might be to tag them with postcodes, even if that&#

If you want discussion, look at regional mail lists, perhaps, if the UK one is anything to go by. I don't share that impression of the data in the UK.

Unfortunately, Maps.me on android is either replete with trackers or now basically doesn't work (the f-droid expurgated version), though the question wasn't about android. At least that was the case with f-droid fairly recently -

That is rather wonderful but, of course, one typically can't use telnet at work "because security". I got left with it in a mode printing escapes afterwards, and needed reset(1), but I guess that's telnet's fault,

I've skimmed the paper, and I'm not sure what to make of it. Definitely you need tools, but even basic profiling is a good start and quite rare. Suggesting changing source code because of the behaviour of a particular compiler v

I said "well-defined" for that sort of reason, but there's more. Fortunately I haven't had to discuss -ffloat-store (which may have been originally for m68k) for a long time.

Indeed, and you can be told you have to use it even when it won't compile the code, or the result won't run correctly (and obviously you should use it and MKL on AMD hardware too). At least it's not as bad as the infamous &q

I'd say the moral is to write standard-conforming, well-defined code, and use standard-conforming compiler options, e.g. not the Intel defaults. Also use the available warnings and diagnostics.

I used to be a compiler maintainer because I was the maintainer for a large scientific suite -- i.e. I was on both sides of the fence -- and I haven't really changed my opinion. The arrogance I've seen has mainly been from scienti

Yes, however typical users do appear to expect or claim that, normally for the Intel compiler, on the basis of myth and not measurement and understanding. I'm not convinced there is typical numerical code across scientific application

Is Somu the same as the current Solo? (Not that I've had much opportunity to exhaust it...) I don't remember seeing that documented, or if the processor/storage is the same. On the topic of the implementation, is there any

Performance counters are vital, and you don't need to grovel the disassembly yourself in association with profiling, even if it's feasible. Get a tool to do it for you; MAQAO is one in that area (x86-specific, and unfortunately

What sort of trouble? I don't see that, though the only reason this system has Ubuntu and not Debian is that seemed necessary for hardware support initially, and I should move to that rather than Ubuntu 20. (In my experience it'

I don't understand the problem. I get microcode updates with apt and general firmware with fwupd (ready to install on next boot from UEFI). As far as I now that's the intended/supported procedure.
