similar to: MMX/3dNow! etc

Are there any plans for Ogg Vorbis to support MMX/3dnow optimizations? I think this is the major reason why the decoding of mp3's is faster than ogg in XMMS.

Dear expeRts, Please find attached the .diff for a bug fix in R-devel 62124. format.ftable() fails to format ftable()s correctly which have no row.vars or no col.vars. That should work with the patch (the example code below also runs correctly for all the (new) 'method's). Cheers, Marius --8<---------------cut here---------------start------------->8--- (ft1 <- ftable(Titanic,

Hi again, I measured my fragment reconstructions against the compiler output from GCC and well - the new codes perform better, so I brushed up my gcc inline assembler skills and made a port. Code is here: http://torus.untergrund.net/code/mmxfrag.c All routines perform much better now. Inter2 alone got a speedup of factor 5 on Pentium-M. Athlon CPU's execute roughly 3 times faster.

Hi guys, I'm facing a problems with samba4 + bind9_dlz that consuming my time for several days. Everything is working fine until samba4 need to update dns when I'm work with more than one DC server. When samba (or bind) need to reload all zones, the module bind9_dlz is shutting down and then all my environment stops and I need to restart the bind to up again. See my log: ... Jan

Mathias, Thanks for your reply. Please, try to start your bind with some debug level and run commando "rndc reload" and see the end of the log. I saw samba source code and found the destroy dns function in dlz_bind9.c and called by turture blz_bind9.c. When dlz_bind9.c is shutting down, I get this error when I try to update dns. update failed: NOTAUTH Failed nsupdate: 2

Using your log parameters, the shutting down message is not showed, but when I reload rndc a get the same effect. Everything is working fine until bond9_dlz needs to reload (and no restart) rndc. When this happens, I need to restart bind and everything works fine again. I'm starting named with named -d 3 -u named and using /var/log/messages. See log using your parameters: # rndc reload

Hello! One note/question hier about specification of control-parameters in the lme(...,control=list(...)) function call: i tried to specify tne number of iteration needed via lme(....,control=list(maxIter=..., niterEM=...,msVerbose=TRUE)) but every time i change the defualt values maxIter (e.g. maxIter=1, niterEM=0) on ones specified by me, the call returns all the iterations needed until

Hi, As I´ve understood things, the Ogg Vorbis format supports more that two channels (stereo). Is there any tools to encode x sourcefiles into one .ogg file? I am a musican and am thrilled with the ide of makeing music in surround (or in more than stereo). This leads to my next question: is there (developing) any decoders for multichannel oggs to, let us say, 4.1 or 5.1 surround? Wouldn´t it

I'm trying to improve Opus on an AMD Geode CPU, which has limited SSE support (called 3DNow!), but MMX. Without optimizations I can only encode 16 bit audio @16KHz with complexity up to 2-3 without underruns. I tried compiling with SSE2/4 optimizations, but all I got was a crash with SIGILL, so I looked into optimized code and found that a good starting point was the dot product, so I

Dear R-help, First of all, thank you VERY much for any help you have time to offer. I greatly appreciate it. I would like to write a function that, given an arbitrary number of factors from a data frame, tabulates the number of occurrences of each unique combination of the factors. Cleary, this works: > table(horse,date,surface) <SNIP> , , surface = TURF

I have a cgi/perl program that I want to use on the same server as my RoR app and I keep getting: The page you were looking for doesn''t exist. You may have mistyped the address or the page may have moved. I load the program to the cgi-bin directory in its own folder /cgi-bin/ fump/ In the /public folder of my app I have the following .htaccess file: # General Apache options

Hello, attached is a gzipped patch file to the lib/mcomp.c source file of theora (as of AnonCVS current version) that implements MMX and extended-MMX optimizations in the most frequently used functions of the encoder (as shown by gprof). This is more a proof of concept than a real request for inclusion into the source tree. My personal intent was more to look deeper into the MMX instruction set

Might you instead consider just adding a -disable-mmx option?

Along with libtheora-1.0alpha5 this is a release of theora-mmx. A drop in replacement that uses MMX assembly to speedup some of the most demanding routines in theora encoding/decoding. Right now it only works on 32bit x86 CPUs. Thanks to everyone whose work made this release possible! Download links: http://downloads.xiph.org/releases/theora/libtheora-mmx-1.0alpha5.tar.bz2

Hi Dale, I will not change the default. I would dislike to see any regressions due to this type of change. -- Mon Ping On Nov 20, 2008, at 10:12 AM, Dale Johannesen wrote: > > On Nov 19, 2008, at 11:57 PMPST, Mon Ping Wang wrote: > >> Hi, >> >> When setting -mattr option on X86, I would like to treat MMX >> separately from SSE levels.

I'm working on changing the MMX implementation to use intrinsics in all cases, which should stop various optimization passes from creating MMX instructions that screw up the x87 stack. Right now the MMX instructions are split between X86InstrMMX.td and X86InstrSSE.td, presumably on the historical grounds that some of them weren't introduced until SSE or SSSE3, and require
