paq8lab 1.0 archiver

**bwt** · 21st November 2019, 01:02

this is forked from paq8pxd. i include the source, maybe the result is 15.9xx.xxx bytes for enwik8 using -s14 option.

Comparing to v47_6 the difference is this:

Yes. Please test it for enwik8 using -s14

@bwt - Could you compile Win64 binary?

And second question: why you didn't use paq8pxd v48_bwt4 as a base?

For paq8pxd v48_bwt4 I've got such scores:

16'429'216 - enwik8 -s6 by Paq8pxd_v48_bwt4 (your score)
16'183'320 - enwik8 -s8 by Paq8pxd_v48_bwt4
15'977'376 - enwik8 -s14 by Paq8pxd_v48_bwt4 - the result was below 16'000'000 bytes.
16'091'113 - enwik8.drt -s14 by Paq8pxd_v48_bwt4

I still forget where i put g.bat for it and where the source bwt4 so I download it from encode forum.

Maybe someone in this forum can help to build it

How about enwik9 ? Have you tested it ?

**Darek** · 21st November 2019, 20:04

I've tried ywo times. Unfortunatelly both attempts ends without success. This version uses more than 32GB of memory and (besides much more timeconsuming) crashes at about 80% of the file - I don't know if it was in the same moment...

My last scores are:
16'525'916 - enwik8 -s6 by Paq8pxd_v48_bwt1 - your score
16'248'408 - enwik8 -s8 by Paq8pxd_v48_bwt1

136'732'561 - enwik9 -s6 by Paq8pxd_v48_bwt1 - your score
126'183'029 - enwik9_1423 -s14 by Paq8pxd_v48_bwt1 - the paq series record, submitted to LTCB as 4'th score at now! With -s15 option program crashes...

16'472'556 - enwik8 -s6 by Paq8pxd_v48_bwt2

126'157'295 - enwik9_1423 -s14 by Paq8pxd_v48_bwt2 - estimate, program didn't finish even on -s14

16'429'216 - enwik8 -s6 by Paq8pxd_v48_bwt4

Did you managed to compile it? If so, how? I'm trying to but it fails with undeclared stuff.

**Shelwien** · 22nd November 2019, 22:01

It compiles with parts other than .cpp taken from this: https://github.com/kaitz/paq8pxd/releases/tag/v47

No, there were binaries published on paq8pxd forum.
Like mentioned above v47_6 - https://encode.su/threads/1464-Paq8p...ll=1#post57094

i have installed mingw 16.1 distro from nuwen.net but when i compiled paq8lab it does not work. Here is the source code and please shelwien or someone help to compile it and run how many enwik8 and enwik9 can be compressed again. thank you

**bwt** · 23rd November 2019, 17:55

this is based on paq8pxd48_bwt1

**Shelwien** · 23rd November 2019, 18:03

1. Get this: https://vorboss.dl.sourceforge.net/p...-rt_v5-rev1.7z
2. Install to C:\mingw720x
3. run g.bat in archive above

**bwt** · 25th November 2019, 08:05

i use devc++ 5.11

**Darek** · 29th November 2019, 12:16

I've tried to compress with -s14 and -s15 options and there are "out of memory" error. This version even not tried to use swap file...
-s14 option uses, as it wrote, 42GB of memory and (strange) -s15 try to use 39GB of memory.
Instead of this I've testes enwik8 with -s6, -s8 and -s13. Comparison to latest version is like follows:

16'553'942 - enwik8 -s6 by Paq8pxd_v47_5
16'267'313 - enwik8 -s8 by Paq8pxd_v47_5
16'027'128 - enwik8 -s15 by Paq8pxd_v47_5
16'099'328 - enwik8.drt -s15 by Paq8pxd_v47_5
126'387'497 - enwik9_1423 -s15 by Paq8pxd_v47_5 - estimated, program finish to compress but didn't add the header..

16'550'555 - enwik8 -s6 by Paq8pxd_v47_6
16'264'217 - enwik8 -s8 by Paq8pxd_v47_6

16'525'916 - enwik8 -s6 by Paq8pxd_v48_bwt1
16'248'408 - enwik8 -s8 by Paq8pxd_v48_bwt1
16'004'759 - enwik8 -s14 by Paq8pxd_v48_bwt1
16'088'990 - enwik8.drt -s14 by Paq8pxd_v48_bwt1
136'732'561 - enwik9 -s6 by Paq8pxd_v48_bwt1
126'183'029 - enwik9_1423 -s14 by Paq8pxd_v48_bwt1

16'472'556 - enwik8 -s6 by Paq8pxd_v48_bwt2
16'228'952 - enwik8 -s8 by Paq8pxd_v48_bwt2
16'001'495 - enwik8 -s14 by Paq8pxd_v48_bwt2
16'088'506 - enwik8.drt -s14 by Paq8pxd_v48_bwt2
126'157'295 - enwik9_1423 -s14 by Paq8pxd_v48_bwt2 - estimated due to crashes

16'429'216 - enwik8 -s6 by Paq8pxd_v48_bwt4
16'183'320 - enwik8 -s8 by Paq8pxd_v48_bwt4
15'977'376 - enwik8 -s14 by Paq8pxd_v48_bwt4
16'091'113 - enwik8.drt -s14 by Paq8pxd_v48_bwt4
125'967'139 - enwik9_1423 -s14 by Paq8pxd_v48_bwt4 - estimated due to issues

16'526'213 - enwik8 -s6 by Paq8lab_2
16'249'207 - enwik8 -s8 by Paq8lab_2
16'024'588 - enwik8 -s13 by Paq8lab_2

That looks that paq8lab_2 version is very similar to bwt1 (slightly worse), then my estimate for -s14/15 is as below:
16'005'546 - enwik8 -s14 by Paq8lab_2 - estimate - unfortunatelly slightly higher than 15'9xx'xxx

16'108'923 - enwik8.drt -s14 by Paq8lab_2 - estimate
126'339'363 - enwik9_1423 -s14 by Paq8lab_2 - estimate

There's a commented out line above that:

Code:

    //U64 scompsize=0;

Also it'd compile if you didn't remove -DNDEBUG:

Code:

                            #ifndef NDEBUG 
                            printf("Stream(%d) block from %0lu to %0lu bytes\n",i,datasegmentlen, out->curpos()-scompsize);
                            scompsize= out->curpos();
                            #endif

still happen error when i have removed -DNDEBUG in g.bat

Change this:

//U64 scompsize=0;

to this:

Code:

U64 scompsize=0;
