"Microsoft has faced criticism for changing the pop-up box encouraging Windows users to upgrade to Windows 10.

Clicking the cross in the top-right hand corner of the pop-up box now agrees to a scheduled upgrade rather than rejecting it.

This has caused confusion as clicking the cross typically closes a pop-up notification.

The upgrade could still be cancelled when the scheduled time for it to begin appeared, Microsoft said.

The change occurred because the update is now labelled "recommended" and many people have their PCs configured to accept recommended updates for security reasons.

@DavidPostill Yea, pretty shady. Security Now covered that issue last week. The correct way to dismiss that box is to click the "Click here to...." text link.

Bob

@MichaelFrank God forbid you leave a computer running for a week without interaction.

And this is why I have auto updates disabled.

And also why if Win10 doesn't stop pissing me off with daily prompts, I'm going to make good on my promise and rip out the update infrastructure.

Hm... or null-route the update servers.

Michael Frank

@Bob My least favourite prompt is the "We installed updates. Click here for more info." that doesn't bloody do anything.

Bob

@allquixotic Nitpick: Are you sure shared memory IPC is significantly slower on Windows vs other contemporary OSes?

If you're using named pipes or (shudder) window messages, sure...

AFAIK shared memory is largely bottlenecked by hardware.

You'd effectively be left with some weird kind of pseudo-segmented memory :P

In fact, you don't even need IPC... could just map files directly and rely on the page cache.

Optimal? Not really. Works? ...yea.

allquixotic

@Bob what files? we can assume that game state is transitory and is very frequently updated by both the AI and the player(s); we're not talking about static data here...

Nicolas Raoul

I decoded an email's attachment with Linux `munpack`, the content is fine but the attachment's filename is like below. Any idea how to decode it? (probably Chinese characters)
=XGBKXBX1cK5scf4s8e53L7WudjT2s34wufT38fp0MXPoteoX=XXX=XGBKXBXsai1xLTwuLQoz8K6vszBMbrFKS5kb2M=X=

allquixotic

if you're creating separate "game state files" (whether it's some kind of well-known DB or a custom binary format), and they reside on disk, eventually it's going to sync them to disk, imposing overhead.

Bob

04:58

@allquixotic The concept of "shared memory" in Windows (not 100% sure about Linux) is analogous to mmap on Linux. You map views of files.

All virtual memory in Windows is supposed to be backed by a file, whether the automatic page files or a custom named file.

allquixotic

@Bob Wouldn't mapping stuff into the virtual address space be limited in size by the size of the virtual address space to begin with?

Bob

There's techniques that allow you to map files without letting them flush to disk, iirc

@allquixotic Views of files. Chunks.

The thing I'm not so sure about... I don't know if re-mapping forces a flush to occur.

Might need another process to hold the same view to keep it in RAM.

allquixotic

I mean, there are only 2^32 (0 to 2^32-1) possible integers you can use to address memory segments within a 32-bit process. If you're going to mmap() some files into your process, the bits of those files you map in, take up some of your memory addresses within your VAS - no?

Bob

@allquixotic Yes. Hence pseudo-segmented memory.

allquixotic

you end up having a sliding window or "aperture" into the larger file, and constantly having to move that around - that sounds like context switches to me

Bob

05:01

Segment 1: 0-1 GB. Segment 2: 2-3 GB. etc.

@allquixotic It's not ideal, no. Obviously having direct access is better.

But as far as IPC goes this is probably as efficient as you can get.

There's no way transferring data through TCP or Unix sockets would be faster.

allquixotic

I'm not sure how many calls to the shared memory architecture and mapping/remapping functions you'd have to make to bottleneck that subsystem on a typical desktop system, but the ceiling is necessarily going to be a lot lower than having those regions of memory directly addressable through the hardware virtual memory manager in a native 64-bit process.

Bob

@allquixotic Yes, definitely worse than just native 64-bit.

allquixotic

but yeah, I wasn't really thinking of shared memory when I wrote that post, and it is probably a good ways faster than other alternatives, short of having the data in-process

Bob

My nitpick was the claim that an OS is significantly slower for IPC :P

allquixotic

there's some non-zero cost associated with effectively having a software virtual memory manager

Bob

05:03

Which is probably true for things like named pipes.

But they aren't designed for high throughput/low latency in the first place.

@allquixotic I wonder how it's implemented.

In theory, the mapping that occurs wouldn't have to be be much more expensive than having to refill the TLB with 64-bit anyway.

With 64-bit you can use huge pages, but I don't think Windows uses them and I know Linux only uses the mid-sized one and even then only in specific scenarios.

There's 4k, 2M and 1G pages in modern x86.

Linux uses 2M at most. I don't think it ever uses 1G.

allquixotic

I recall reading somewhere, and maybe it was really outdated info from the NT days, that the Windows kernel's time slices for thread running time were quite coarse-grained compared to, say, a 1000 Hz Linux scheduler

Bob

Ah, Windows has large page support too but only for privileged users and only when specifically requested.

And probably for 2M only too.

allquixotic

unless new Windows OSes have adjusted that, that could be a source of overhead any time you do something involving a context switch; and shmem almost certainly involves two (user -> kernel and kernel -> user)

Bob

Linux was also on specific request only but at some point a patch came in to do it automatically.

@allquixotic Hm. I'm not too familiar with the details there.

@allquixotic "adaptive" - as of Windows 2000:

> A context switching rate of 300 per second per processor is a moderate amount; a rate of 1000 per second or more is high. Values at this high level may be a problem.

So it can switch very often, as required.

technet.microsoft.com/en-us/library/cc938613.aspx

allquixotic

kinda like dynticks with 1000Hz then O.o

might be interesting to measure the context switches per second during a heavily loaded game of Stellaris :P

Bob

05:11

Assuming it does the dumb multi-process/shmem thing!

64-bit would be far easier, faster and more reliable.

@allquixotic There's also the question of whether the syscall requires a context switch at all...

Apparently Linux at least will avoid that in certain contexts, pun intended

allquixotic

Linux avoids context switches when doing shmem stuff? or just some syscalls?

Bob

@allquixotic "some" syscalls. I don't know which.

allquixotic

shmem really, really seems like the kind of thing that a userspace process couldn't just do on its own without kernel help -- I mean, it involves taking a region of memory that's literally not within the process's memory segment and doing stuff to it to allocate it and make it available within the process's virtual address space

when that kind of thing has to happen within, say, an Nvidia graphics driver, to map stuff into the process so the userspace driver stack can beat on it, it has to do a context switch into the driver to do the kernel-side allocations to support it.

Bob

> Typically a system call only leads to a context switch if the call will block, or if the caller has used up its timeslice; otherwise, it's just a couple of relatively cheap protection domain crossings.

allquixotic

a userspace process really shouldn't have the kind of permissions necessary to do that without kernel help :P

Bob

05:17

@allquixotic Well, apparently modern CPUs can avoid flushing the TLB on a 'context switch' (speaking of which, the MIPS I played with could do that too!)

you're pretty much preserving registers and changing stacks (changing the stack pointer)

so it's not really expensive at all

The most expensive part traditionally would probably be the TLB flush

allquixotic

I feel almost compelled to write a C program exercising this functionality on Linux and Windows and see if there's any performance difference, and see how many times it can do it per second

Bob

lol

I suspect that you'll find the Linux one faster, if only because there's significantly more indirection in the Windows one (unless you want to use NT calls directly)

allquixotic

general idea would be to compile a 32-bit program that allocates a large shmem region and does something like... write out a series of increasing unsigned 64-bit integers into the address space and read them back as fast as possible up until a pre-defined limit, then stop and report the time taken

Bob

But it shouldn't be that much faster than Windows - end of the day, most of your time is still spent in reading the data from RAM.

allquixotic

really the question I have is how many round trips are possible per second

because the number of round trips per second when directly accessing RAM within a userspace virtual address space probably numbers in the billions at this point (?)

Bob

05:23

@allquixotic You can probably speed up Linux a lot with MAP_HUGETLB and MAP_HUGE_1GB

For Windows, it's MEM_LARGE_PAGES

allquixotic

DMI advertises 5 or 10 Gigatransactions per second (can't remember the exact number); wonder how many DMI transaction slices it takes to do a memory read on Skylake

ideal would be 1 :P

Bob

@allquixotic 7-cpu.com/cpu/Skylake.html

Using 1 GB huge pages will save you some ~256x the page table walks :P

allquixotic

oooo

Journeyman Geek

This is probably how other people feel when they walk in on me geeking out over hardware ;p

(I have no idea what's going on)

Bob

lol

I'm relying heavily on a single OS-dev course -_-

But it was very good info on how *nixy OSes handle virtual memory, and I have a habit of getting stuck in big branching links with dozens of tabs of info.

@allquixotic Another thing to keep in mind, assuming context switches are primarily expensive due to having to discard the TLB: you can only really hold some 4 GB of data TLB entries at once, so... you'd have to do a fair bit of the work of a context switch when reading such a massive amount of RAM, even in a 64-bit process :P

And if we're talking not using huge pages (which Linux only sometimes does and Windows doesn't do at all without specific request), well. That's now down to some 250 kB. Total.

allquixotic

05:34

@Bob little math from there and you can hit RAM about 615 million times per second at 4 GHz

Bob

@allquixotic Remember, though, that's only for direct access or addresses already in the TLB.

e.g. repeated access to one address.

If you're scanning memory with 4kB pages, the time spent mapping those pages would be significant.

256 kB in data TLB, ~6 MB in second-level (slower) TLB.

Every 256 kB you're doing that mini-context-switch.

A context switch is saving registers (very fast), changing stacks (should be fast?), flushing TLB (slow-ish). And the sysenter/sysexit/interrupt (couple cycles, dropped pipeline?).

bwDraco

Oy vey. Not into system programming.

Dropped pipeline is way more than a few cycles.

It's more like 10-15 cycles.

Bob

@bwDraco While we're talking reloading the TLB mappings with some 42 cycles (possibly many more if caching doesn't kick in considering most page tables are 3-4 levels nested)... 10-15 once per switch is a fairly negligible part :P

But of course I don't have the real numbers.

But my "?" was more not knowing if sysenter actually drops the pipeline.

Camera frame rates are higher than ever, too. I've already cut down on loads of duplicates and unusable images. If I do it the way some pros do and shoot hundreds of images a game, this laptop is clearly not going to be adequate.

...especially if they are from today's breed of super-high-resolution cameras (*cough* Nikon D810 *cough* Sony A7R II *cough* Canon EOS 5DS *cough*).

Interesting new feature on these new HEDT processors: Turbo Boost Max Technology 3.0.

Special software can identify which cores can run the fastest (due to normal variation, just as some chips can overclock better than others) and put the most CPU-intensive tasks onto those cores first.

That can prove handy for overclockers, too, as they can identify which core is the slowest and make the very most of every core on the chip by adjusting each core's clocks individually.

It'll push beyond the processor's specified Turbo speed, yet still be considered within spec.

Let me save you some time: if the question about my workplace involves "is this problem caused by infrastructure", the answer is always "yes".

A coworker from other department was just telling me how it takes 7hrs to send 45k emails, and someone somewhere else sendes 800k+ emails in less than that time.

We also have blackouts every two weeks and near-daily internet outages.

And the situation of the datacenters... just don't ask.

@allquixotic Although I wasn't calling Drupal slow, I mean it's not slim because to just start using it you need to (1) create user profiles, (2) create a content type, (3) create an input text type, (4) something I'm probably forgetting

Compared with other popular CMS's, Drupal is much more flexible, but with the cost of being much more complex.
