[Issue 5612] core.cpuid not implemented on 64
http://d.puremagic.com/issues/show_bug.cgi?id=5612 --- Comment #4 from Russel Winder rus...@russel.org.uk 2011-02-20 02:51:59 PST --- I don't agree this is an enhancement, it is a bug, even if the 64-bit stuff is in early days. OpenMP, OpenMPI, just::thread and all the other C, C++ and Fortran paralellism frameworks handle this correctly. Why is this being handled by assembly code, all the operating systems must have APIs for handling this? Of course with Mac hardware with 64-bit processors where the boot ROM is 32-bit the OS boots 32-bit -- since Mac OS X refuses to boot 64-bit in this case. A hypothesis: the current assembly code can only deal with a single processor which is why it reports 4 in 32-bit mode on my dual quad-core workstation. If this is the case should a new bug be raised or can this be handled here? -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

[Issue 4944] Missing tzname even though we have tzset

The current implementation of the spell checker (as far as I can tell) always
finds the nearest match to the incorrectly spelled symbol.
So the following example:
struct S2 {}
struct S10 {}
void main()
{
S10 a = S();
}
Will emit the error:
spell.d(6): Error: undefined identifier S, did you mean struct S2?
Whereas it would be an improvement in these cases if it were to suggest the lhs
type instead.

[Issue 5612] core.cpuid not implemented on 64
http://d.puremagic.com/issues/show_bug.cgi?id=5612 --- Comment #6 from Don clugd...@yahoo.com.au 2011-02-20 08:40:20 PST --- (In reply to comment #4) I don't agree this is an enhancement, it is a bug, It's neither. It is a task. Bugzilla's options are ridiculously limited. Why is this being handled by assembly code, all the operating systems must have APIs for handling this? The most recent ones do, the older ones don't. Really, this code is primarily intended for determining which features should be supported for low-level operations used by the runtime; and as such, it must be available at a very early stage in the initialization process, regardless of the OS. It replaces several ad-hoc and incorrect functions which had been used in the runtime. It would be good to supplement this with systems calls for the most recent OSes, but to do this without breaking older OSes. Although, probably all 64-bit OSes support it, so maybe it's only a issue for 32-bit systems. Of course with Mac hardware with 64-bit processors where the boot ROM is 32-bit the OS boots 32-bit -- since Mac OS X refuses to boot 64-bit in this case. A hypothesis: the current assembly code can only deal with a single processor which is why it reports 4 in 32-bit mode on my dual quad-core workstation. If this is the case should a new bug be raised or can this be handled here? That should be a new bug. The value should be correct, if the BIOS has done its job in setting the processor APIC values correctly. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

[Issue 5623] New: Slow GC with large heaps

Created an attachment (id=918)
The patch.
Here's a GC benchmark and its performance on the stock GC.
import std.stdio, std.datetime, core.memory, std.conv;
void main(string[] args) {
if(args.length 2) {
stderr.writeln(Need size.);
return;
}
immutable mul = to!size_t(args[1]);
auto ptr = GC.malloc(mul * 1_048_576, GC.BlkAttr.NO_SCAN);
auto sw = StopWatch(autoStart);
GC.collect();
immutable msec = sw.peek.msecs;
writefln(Collected a %s megabyte heap in %s milliseconds.,
mul, msec);
}
Outputs for various sizes (pre-patch):
Collected a 10 megabyte heap in 1 milliseconds.
Collected a 50 megabyte heap in 4 milliseconds.
Collected a 200 megabyte heap in 16 milliseconds.
Collected a 500 megabyte heap in 41 milliseconds.
Collected a 1000 megabyte heap in 80 milliseconds.
Collected a 5000 megabyte heap in 397 milliseconds.
Collected a 1 megabyte heap in 801 milliseconds.
Collected a 3 megabyte heap in 2454 milliseconds.
Collected a 5 megabyte heap in 4096 milliseconds.
Attached is a patch that creates separate large and small object pools, only
stores the GC bits for the large object pool at pagesize offsets, not 16-byte
offsets, and stores, rather than computes, offsets for B_PAGEPLUS pages. So
far, all unit tests for Phobos, dstats and std.parallelism/parallelfuture pass
with this enabled.
Here are the new benchmarks (post-patch):
Collected a 10 megabyte heap in 0 milliseconds.
Collected a 50 megabyte heap in 0 milliseconds.
Collected a 250 megabyte heap in 1 milliseconds.
Collected a 500 megabyte heap in 0 milliseconds.
Collected a 1000 megabyte heap in 1 milliseconds.
Collected a 5000 megabyte heap in 3 milliseconds.
Collected a 1 megabyte heap in 6 milliseconds.
Collected a 3 megabyte heap in 16 milliseconds.
Collected a 5 megabyte heap in 26 milliseconds.

http://d.puremagic.com/issues/show_bug.cgi?id=5623 Walter Bright bugzi...@digitalmars.com changed: What|Removed |Added CC||bugzi...@digitalmars.com --- Comment #2 from Walter Bright bugzi...@digitalmars.com 2011-02-20 13:03:57 PST --- More explanation from David from the n.g.: I've found a way to speed up the GC massively on large heaps without excessive ripple effects. Technically it's still O(N), but with about a hundred fold smaller constant in the case of large heaps with most stuff not scanned. Now, I think the O(N) (where N is the total size of the heap) term has such a small constant that it's for almost all practcal purposes the GC is O(S) (where S is the size of the scanned portion of the heap). It also no longer has any O(N^2) pathological case (which I had discovered while reading the code). So far all unittests for Phobos, dstats and std.parallelism/parallelfuture pass with this enabled. Please test some other code so we can wring out the corner cases in time for the next release. Basically all I did was diverge the Pool struct slightly into large and small object sub-varieties. The large object sub-variety is used to allocate objects of at least a page. It only stores gcbits at page-size offsets, and tracks the offsets of B_PAGEPLUS bins from the nearest B_PAGE bin so that they can be found in O(1). I also added a field to the Pool struct so that the number of free pages in a pool can be tracked in O(1). This should drastically lessen the time it takes to perform large allocations on large heaps. Right now a free memory region is found by a linear search through the pools in the case of large allocations. Unfortunately, I don't see any easy way to fix this. This patch at least allows short circuiting a large number of pools, if there isn't enough free space in the whole pool, let alone contiguous space. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

If no large objects are allocated for the duration of the program, then my patch has virtually no effect.) This benchmark does tons of small object allocation and no large object allocation. The small difference between with and without patch may even just be noise. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

[Issue 5630] New: array() of iterable of immutable items
http://d.puremagic.com/issues/show_bug.cgi?id=5630
Summary: array() of iterable of immutable items
Product: D
Version: D2
Platform: x86
OS/Version: Windows
Status: NEW
Keywords: rejects-valid
Severity: normal
Priority: P2
Component: Phobos
AssignedTo: nob...@puremagic.com
ReportedBy: bearophile_h...@eml.cc
--- Comment #0 from bearophile_h...@eml.cc 2011-02-20 15:01:52 PST ---
A D2 program:
import std.algorithm: map;
import std.array: array;
void main() {
auto r = map!q{ A[0] }([0, 1, 2]);
auto a = array(r); // Error: result[i] isn't mutable
assert(a == AAA);
}
DMD 2.052 gives the errors:
...\dmd\src\phobos\std\array.d(62): Error: result[i] isn't mutable
test.d(5): Error: template instance std.array.array!(Map!(result,int[])) error
instantiating
In my opinion array() needs to be able to build an array of immutable items
too, like a string from its immutable chars.

[Issue 5623] Slow GC with large heaps
http://d.puremagic.com/issues/show_bug.cgi?id=5623 --- Comment #5 from bearophile_h...@eml.cc 2011-02-20 15:07:17 PST --- (In reply to comment #4) I'm not sure what this told us that we didn't already know, though. Thank you for the timings. This synthetic benchmark tells us something important: that for a different situation (but an important one, because that benchmark is quite revealing, despite being so simple) your patch doesn't make the GC significantly worse (it may even improve things a bit). -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---
[Issue 5623] Slow GC with large heaps

The purpose of a 3-legged comparison: the Java timing is used as a rough zero-scale, to allow an estimate of the absolute difference between the other two timings. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---
[Issue 5278] DMD generates programs that immediately segfault.
http://d.puremagic.com/issues/show_bug.cgi?id=5278 Vladimir thecybersha...@gmail.com changed: What|Removed |Added CC||thecybersha...@gmail.com --- Comment #12 from Vladimir thecybersha...@gmail.com 2011-02-20 15:27:04 PST --- I just thought I'd mention that I had some similar problems with DMD on Gentoo due to bad permissions of certain libraries. Do your programs run under root? If so, check permissions for libphobos and whatever 32-bit libraries your program / libphobos uses (glibc? libstdc++?). -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---
