Hello, I've integrated the tests and AVX pitch code into my fork: https://github.com/rvelea/opus/commits/master I ran test_opus_decode and it seems to be running OK. I'll do some more measurements with VTUNE and the new pitch test in the following days and get back to you with a pull request and the data. In the meantime if you have time to give it a quick look and maybe point out any

Hi! AFAIK, there are different version of AVX; maybe clarify which versions you use, and how you detect the availability of the instructions needed. Also you could point out which CPUs are expected to be supported. Also consider that besides Intel there still exists AMD ;-) Regards, Ulrich >>> "Velea, Radu" <radu.velea at intel.com> schrieb am 20.01.2016 um 19:02 in

Hello, I've created a pull request[1] to enable configuration to search for AVX support and set OPUS_X86_MAY_HAVE_AVX accordingly. Please review.

Hello, I'm currently looking to see if Opus could benefit from AVX/AVX2 instructions and I've made some experiments optimizing xcorr_kernel_* function in celt using AVX2 intrinsics and got about 1.5x-1.6x speedup over SSE floating point version in pitch_sse.c. Have AVX optimizations been tried in Opus? Is there someone I could talk to about optimizing compute intensive tasks in Opus using

Yes, Thank you. I'll follow up with the AVX code and tests for pitch code. Radu -----Original Message----- From: opus-bounces at xiph.org [mailto:opus-bounces at xiph.org] On Behalf Of Timothy B.

No, I'm not aware of anyone trying out AVX. If you want a more real-time exchange, the IRC channel #opus on freenode is the correct place. Otherwise feel free to start the

I took a brief look and didn't see any obvious bugs, but we will want you to organize the commits so that each one is independently compilable and testable (and doesn't break anything) before you submit them. I

Velea, Radu wrote: > Yes, > > Thank you. I'll follow up with the AVX code and tests for pitch code. Actually, I lied. Because you update opus_select_arch(), you can now return a value for arch (4) that is larger than the maximum we currently support (3). This doesn't actually cause failures, because we mask with OPUS_ARCHMASK, but it does mean that a CPU with AVX will invoke

Sorry for the off-topic question but I need advice on a buying a ISCSI SAN for 4-6 servers running CentOS 4.4 .The main purpose for the SAN is to store email accounts (that will be accessed by imap - dovecot) and other documents. Minimal redundancy is required (e.g. dual power supplies, battery backed write cache or mirrored controllers) and price for a 2 TB configuration should be under $ 10000.

Hello there, Can anyone help me with a problem i have.... I have an ethernet LAN, made over dumb fast-ethernet switches (10/100mbit) without management, so there is no IP for the switches. What I want, if possible, is to find out if a switch is down or not. It''s like with routers... if you want to find out if a router is OK, either you send ICMP directly to the router, or to a host

Hi all, I am new to Hearbeat so please be kind :) I also posted this on Linux-HA lists with no responses so I posted it here. I have successfully configure two machines to use heartbeat to cluster httpd. The two nodes are called etk-1 and etk-2. I am trying to configure another two machines to act as a separate cluster (on the same IP subnet). These two nodes are called radu-1 and radu-2.

Hello there, Can someone please explain why do one neeed IMQ ? I can already shape incoming traffic on my nat router by creating qdiscs on LAN-side interface. I have done some tests, whith simple bandwidth limmiting, and it works. I''ve read just about all the stuff on www.linuximq.net ... but couldn''t make myself an ideea on why would someone need IMQ for ingress policing ...

Hello everyone! We are working on writing a paper about testing the reliability of C compilers by using Csmith (a random C99 program generator). A previous testing effort, using Csmith, found 202 LLVM bugs, which represented 2% of all reported bugs at that time (PDF: https://www.flux.utah.edu/download?uid=114 <https://www.flux.utah.edu/download?uid=114>): . However, after this paper was

Hey guys, thx for talking your time to answer this post, i much appreciate it. 1. is dev in rails under windows a great idea.i can think of 10000 reasons, i know, bu i can;t install linux on my PC, for now at least. the compamy that i am working for wants me to install all of the programs i need to develop a free lancer site, like this one http://www.bestjobs.ro/(if u look at the right upper
