Shows that as the MCU increases, the OpenMP extra overhead is amortized and OpenMP becomes as fast as the pthreads implementation. The last chart http://lampiao.lsc.ic.unicamp.br/~piga/gsoc_2008/systime.png Shows that both pthreads and OpenMP overhead decreases as what seems to be a logarithmic function of the MCU size. This was a great experiment, and from what I can conclude, the OpenMP implementation can be as good as the pthread. Therefore maybe it is...

...but they are called too many times. The time spent to create and synchronize threads is greater than the speed up gains. We need functions that are called a few times and spend many cpu time. Also data dependency should be the lowest as possible. According to the model that i did ( http://lampiao.lsc.ic.unicamp.br/~piga/gsoc_2008/implementation.pdf<http://lampiao.lsc.ic.unicamp.br/%7Epiga/gsoc_2008/implementation.pdf>) the decoding time should be reduced in 33%, but it was just 10% for pthread an 5% for openMP. I used a video with 1440x1080. The pthread implementation has 3 threads and t...

Hello, I work in a hosting company, we have tens of Xen dom0 running just fine, but unfortunately we do have a few that get out of control. Reported behaviour : - dom0 uses more and more memory - no process can be found using that memory - at some point, oom killer kicks in, and kills everything, until even ssh the box becomes hard - when there is really no more process to kill, it crashes

...d implementation of these functions: (c_dec_dc_unpredict_mcu_plane + oc_dec_frags_recon_mcu_plane) and (oc_state_loop_filter_frag_rows + oc_state_borders_fill_rows) as explained in my previous email. But the results were not good. They were equal the implementation without pipeline. http://lampiao.lsc.ic.unicamp.br/~piga/gsoc_2008/comparison.png http://lampiao.lsc.ic.unicamp.br/~piga/gsoc_2008/speedup.png http://lampiao.lsc.ic.unicamp.br/~piga/gsoc_2008/systime.png Next I tried to do some improvements, but without success. I think that the implementation as it is, could not be improved more wi...

Hi, I'm trying to synchronize user accounts from LDAP to Samba 4 AD (using LSC) but it seems that password update through ldap is not allowed. I failed to find details about it, but can someone confirm that unicodePwd cannot be read / wrote trough a LDAPS connection ? Is there any workaround ?

Hi, I have some troubles with voicemail sending message to my email address. Do I have to configure sendmail to use Voicemail ? What's about sendmail configuration ? In voicemail. i have lines like this : [default] 1000 => 1234, xxxx yyyy,beasse.lsc@wanadoo.fr I don't see what's password 1234 is ? (password for what ?) But i never received any mail with wav file attached in my beasse.lsc mailbox (wanadoo.fr) The message and the files are in /var/spool/..../1000/INBOX If someone can help me ?

Hello I would like to ask if it's possible to display Theora logo at http://ronja.twibright.com/sw.php I use Theora for automatically generated videos at http://ronja.twibright.com/3d/ If yes can I please have the master of the logo? I cannot use the small logo you have on the website. Thanks, Karel Kulhavy

Hi, The Integration with LEON (first part of my GSoC) is completed. http://atlas.lsc.ic.unicamp.br/~andre.lnc/theora_integration_with_leon3_full.png At the last week I had (leon3 + linux + libtheora) and (leon3 + send_vector_of_input + theora hardware) working ok.

Hello people My name is Felipe and I sent a proposal to the Google Summer of Code that the goal is to get a FPGA embeded system decoding Theora Streams in real-time. It was accepted and the mentor is the Ralph Giles. The proposal can be viewd here: http://atlas.lsc.ic.unicamp.br/~portavales/wp-content/uploads/2006/05/soc_proposal.txt There is also a presentation with a better division of the hardware modules: http://svn.xiph.org/trunk/theora-fpga/doc/hard_theora.pdf Now, I'm working on it, and today I did a simple implementation of the IDctSlow procedu...

...workstations are linux ltsp and all windows is done via rdp. Getting rid of the openldap is too painful to contemplate. Even if I was willing to more all the authentication and authorization stuff to ad would still need openldap. Seen references to solutions to sync ad to openldap like: https://lsc-project.org/documentation/howto/activedirectory Suspect there are other ways to attack the problem. I'm willing to live with the issue of not being able to sync passwords from kerberos -> ldap. May switch to kerberos for authentication at some point. I have set up a lab environment to te...

(I posted this on xen-users last week, and nobody seemed to know what was up. It is time, I suppose then, to dust off the debugger; I was hoping one of you could point me in the correct direction to begin troubleshooting this.)

I have tried to add a plunging to the "libtheora-1.0beta2" (network bandwidth measuring component was added) and Got it success for some far now the problem is when it is added the encoding process get extremely slow (around 20 seconds delay). I think that the problem is with my modified Makefile (some flag may have missed). the following is my modified Makefile.am which is in the

I notice that the user is not able to set their own CFLAGS or LDFLAGS in the ao, ogg, vorbis, and voribs-tools projects. Is there a reason for this? I understand the fact that these modules want to set extremely high optimization flags, and that most users won't know what these are offhand, but there are times when it is useful for the user to specify their own CFLAGS/LDFLAGS. For example,
