Library routines that are included with the language as per the standard. They are just as much a part of "C++" as the compiler itself is.

How would you know if you didn't use it?

We've been using it without problems for a lot longer than that.

Heck, we've been using stuff from Boost a lot longer than that. Much of which is going to be included in the next standard.

Even the template error messages are readable these days.

Well, I consider knowing the standard library to be an integral part of being a programmer. Knowing it and choosing not to use it for a particular reason is one thing, but not even learning it is leaving a lot of potential productivity on the table.

Guided by an educated guess as to where it where to start looking, yes. Knowing the algorithms intimately means having a pretty good idea what can be vectorised (SSE) and what can be parallelised.

Who said anything about randomly revisiting assumptions?

I was revisiting a particular routine that I know is a code hotspot and seeing if I could speed it up more with some features of the new compiler.

As part of that investigation I tested it with straight casting and found that I got an improvement. Looking at the assembler I could see why so I then made the change universal.

If the float-to-int conversion routine wasn't actually used in that particular function then I might not have noticed the difference at that time; OTOH that particular function has a lot of performance tricks in it because it is so critical so it's not surprising to see the conversion routine in there.

Which are excellent reasons for rolling-your-own allocator and having perfectly well-defined behaviour.

Previously you said you used glibc, and glibc's different implementations of malloc() were responsible for your problems.

Since glibc is open-source, couldn't you have read the source code and kept tabs on that? Even better, you could have modified glibc (or derived your own allocator from it) to suit your needs as long as you published your modifications and linked to your modified version dynamically.

It would have saved you a "nasty few weeks" tracking down mysterious behaviour.

That's what good about writing conformant code. Not that it can magically make your program work when someone pulls the plug out of the wall.

Only if you mean something different by "relying".

If you mean it in the sense that Michael raised it and I explained it, then "No". As long as you limit yourself to the assumptions I outlined, you aren't relying on the undefined behaviour at all.

If you mean it in the sense that you need it to give you memory for your program to do something useful, then sure, lots of programs fall into that category -- but that's irrelevant to the point at hand, and it would have been a trite observation for anyone to make.

>And everyone is vulnerable to having their program run

No. The program may not be able to do the operation requested, but that's not the same as "running into trouble". If you user's computer doesn't have the resources and they can't free some up, that's life -- but that wasn't your problem. You not only needed those resources, you need them in a particular way that is specifically not guaranteed by the standard (in fact, it even states that you shouldn't rely on it).

As I said, whether there are sufficient resources to do useful work or not is a completely different proposition.

I also disagree that your malloc() obeys the defined behaviour, because the standard quite clearly states that the malloc() function allocates space for an object whose size is specified by the size parameter and if the space cannot be allocated, a null pointer is returned.

But even your pathological malloc() wouldn't cause undefined behaviour in a conformant program. It would probably severely curtail it's ability to do something useful, but it's behaviour would still be well-defined.

Again, you're using "relying" in a different sense.

If that's the case then that's the case.

But your problem was that if the addresses it returned didn't have certain characteristics, your programs would "behave weird". That's relying on undefined (or possibly unspecified in this case) behaviour.

Well, in our case that class encompasses most of the operations that we have been able to parallelise. Linux IPC may be fast for IPC, but it's still slow compared to what's possible with threading.

I did say it was a specific case and the communications overhead would have been an issue. As I showed in my previous post, even ignoring the data copying cost (in particular the 100 MB copied up-front), the 1-byte ping-pong times you got would take up half of the total processing times per work item. Two processors would be slower than a single processor using serial code!

Thousands of times faster?
