Server :: Setting Up A Cluster Specifically For 3D Video Rendering?
Nov 1, 2010
I'm planning on setting up a server cluster specifically for 3D video rendering. In order to maximize speed I wanna use OpenGL hardware acceleration for that and I'm pretty sure that I have to use an NVIDIA video card if I want the whole thing working reliably. Will I be able to start an X-Server with GLX on an NVIDIA video card that doesn't have a monitor connected to it? And what will be the maximum "virtual" display resolution that I can use?
Since I wanna have several servers running side-by-side I really don't have the room for any monitors.Just to avoid misunderstandings: It is not my intention to show what's being rendered to anyone in real time. I will only create video files that can be downloaded later. I'm already pretty sure that this will work, probably using "CustomEDID" or something like that, but I don't have a suitable setup available to test it right now.

If I was to set up a Cluster, I know it wouldn't make much difference to loading up my browser, but would all heavy duty programs (Video Encoders mainly) work with it, or would I need to use programs specifically designed for cluster use?

I downloaded an FLV video and placed an extra MP3 file over it. Two files. Total: 30 MBI experimented with about seven rendering containers, and QuickTime renderer was the only rendering container that didn't result in sped-up/compressed video or correct rendering for just fifteen seconds.How in the name of all that is holy did this rendering end up with 570 extra MB?

I'm having a very strange problem with red hat cluster. After testing it in the lab, I tried to install a new cluster and received the following error: cman not started: Cannot start, cluster name is too long or other CCS error /usr/sbin/cman_tool: aisexec daemon didn't start I've checked the internet for that error, but nothing. I decided to to take the example from cluster.conf man, which looks like that :
[Code]...
And still I get the same error. I can find my servers both from DNS (FQDN and short name) and they also appear in /etc/hosts.

I am completely new to Ubuntu and so far am pretty happy. I am running into an issue playing web videos, ..... (flash) as well as html5. What is happening is that the CPU is doing all the work instead of the GPU causing the video to skip/stutter, here are the system specs.
MSI K7N2 Delta 2 LSR (latest bios)
AMD Athlon XP 3000+ (Barton)
2GB's PC3200
nVidia 6800GT (AGP)
Ubuntu 10.10 32bit (fresh Install
nVidia driver 260.19.06
When video is played the CPU's useage climbs to 100% and video lags. Again I am completely new to Ubuntu as well as Linux but I am trying, lol.

I want to set up a cluster for scientific computing (mainly statistical stuff with R). I have a few conceptual questions. First, is there a difference between a Beowulf cluster and a cluster that has single-system image ("SSI," e.g. using openSSI or LinuxPMI)? If so, what's the difference? Second, if there is a difference between Beowulf and SSI, which one is better for scientific computing? Third, does using Eucalyptus make sense for scientific computing or is this more suitable for IO-oriented operations such as web service or databases

I've tried many, many different ways of setting up the cluster.conf file, but every time I start the cman service I get a message telling me "corosync died: could not read cluster configuration".This means nothing to me, nor can I find logs, or anything on the net about this message. I'm ultimately just trying to run a simple GFS2 config on 2 Ubuntu 9.10 desktop nodes, but I can't even get a basic cluster config going.What am I missing? I've been at this for days.
Code:
<cluster name="example" config_version="1">
<clusternodes>
[code]...

I am trying to do the cluster storage with the Rock Cluster storage operating system . I have install the rock cluster on the main server . and I want to connect the client with the PXE boot . when I starting the client then it boot from the PXE boot into the mode of compute node. but it ask the where is to be stored the I have give the path..then server says that not able to find the directory path.
Steps:-
1) insert-ethers
2) client is started with the PXE boot.
3) it detects the dhcp .
4) At last it demand where is to be started by cd-rom, harddisk ,nfs etc.
then I started with the nfs and I have given the lanIp of server.and server is detecting the client but client is not finding the filesystem directory. into export partition directory but it is not taking path.
PATH:-
/export/rock/install it is not finding this path then it is not able to start the o/s from PXE boot..Is there any solution and manual of rock or anyother solution then u can reply to me...

I am trying to set up a video streaming server on my Gnu/Linux Ubuntu 10.10. I want to be able to stream videos that I have on my computer to my friends who aren't on my network.streaming audio applications but that won't help me. Most of the tools available are only for sharing within your own network.

I have Compiz Config Settings Manager installed on my Ubuntu 10.04 machine. All the effects are working properly and everything is running fine. However when i play video with VLC Media Player, i would only get audio and no video. After looking this up i changed the output to X11 vidoe Output. I started getting video and audio. But when i switch to fullscreen mode the fullscreen video window is rendered by Compiz and thus has all of those window effects like wobbly, minimize, maximize and stuff are also applied to the full screen video. It also does not have all those controls that vlc normally shows when you wiggle your mouse in full-screen mode. I tried disabling the Video Playback option from the CCSM window, but to no avail.
The same thing also happens for the full screen view of Google Chrome. And the only way to leave full screen is to press F11 again. In this case the tab stacking area which drops down doesn't appear at all, also the exit full screen option which too drops down also does not appear. It seems Compiz is blocking all of those interactive buttons like the floating control panel in VLC and Tab stacking area in Chrome.

Our Apache server is pretty much configured straight out of the box, and I've noticed it is using far more CPU and less memory than another server where I have the following:
RLimitCPU 8
RLimitMEM 100000000
RLimitNPROC 24
The Apache documentation says that if these aren't set, the values are obtain from the OS. How can you tell what those are? I'd like to see if I can tune Apache's performance, but I don't even know if these values are higher or lower than what it's currently using...

whenever I video chat with someone the image from my webcam is clear but the video from the person on the other end is messed up. It is as if it does not render correctly, it's washed out and it looks like a full image and 2 cut off images, one on the bottom and one the top of the full image. Has anyone else encountered this? The PC has a Radeon 9800 Pro AGP card with the ATI drivers installed. Other video plays fine, ....., dvd, avi and mkvs.

I recently downloaded Frets On Fire and the HRP Polymer pack for Duke3D...Duke3D runs fine with just EDuke32 and no mods, just Duke3D and EDuke32. But when I try the HRP Polymer pack, it says in Terminal "NVIDIA: Direct Rendering failed, attempting indirect rendering." This is fine...if I want the game to lag like hell, I'm sure my video card and the driver for it support DR, the video card is a NVIDIA Geforce FX 5200, the same message appears in terminal when I run Frets On Fire, I think it does with other games too, if someone could explain how to enable Direct Rendering.

I am trying to build GFS2 cluster with 2 or 3 Fedora 14 nodes, but I've encountered some problems from the start. First luci does not work at all in Fedora 14. There is no luci_admin and even if I manage to start luci service, I get a blank white screen when I try to open it from the browser. I've googled a bit and found that I'd might be able to setup GFS if I manage to build cluster.conf manually and start the cluster suite, but I cannot find documentation on how to create cluster.conf anywhere. If anyone knows how to setup GFS2 without a cluster suite or how to configure cluster.conf.

I am working in a project that needs to set up an Apache Web Cluster. The cluster needs to be High-availability (HA) cluster and Load-balancing cluster. Someone mentioned the use of Red Hat Cluster Suite, but, honestly, I can't figure out how it works, I haven't been able to configure it correctly. The project currently have two nodes, but we need to support at least three nodes in the cluster.

I'm trying to build cluster computer system using redhat linux enterprise 5.5. And I'm on the step to set up the NFS mounting. (step 3 of part VI on this paper: However, I kept getting "permission denied" when I used the command "mount -t" to mount the slave node onto the hard drive of the master node. Even when I edited /etc/fstab file to make it automatically set up during booting, I still receive the same result. By the way, I've already logged in as a root user on both slave and master nodes.

I am having an issue with LVM on a 2 node cluster. We are using powerpath for external drives. We had a request to increase /apps filesystem which is EXT3.
On the first node we did:
pvcreate /dev/emcpowercx1 and /dev/emcpowercw2
Then....
vgextend apps_vg /dev/emcpowercw2 /dev/emcpowercx1
lvresize -L +60G /dev/apps_vg/apps_lv
resize2fs /dev/apps_vg/apps_lv
Everything went on well , we got the /apps increased. But on the second node when I do pvs.
I am getting following error:
WARNING: Duplicate VG name apps_vg: RnD1W1-peb1-JWay-MyMa-WJfb-41TE-cLwvzL (created here) takes precedence over ttOYXY-dY4h-l91r-bokz-1q5c-kn3k-MCvzUX
How can I proceed from here?

I have setup a MySQL High Availability Cluster with two nodes using DRBD & Heartbeat. I have successfully installed the cluster but one question which is still not solved is that Heartbeat monitors failover of network or server failure, etc.
What will happen if MySQL service gets stopped or do not start. This heartbeat-DRBD cluster does not take any action on that part. Now I want to enable this feature too which also monitors MySQL service. I have gone through MON help on web but could not find out any good step by step tutorial.

I have a HA cluster, all nodes have same network supplied by one ISP. And if the error occur with ISP the system will fail. So I want to set up HA cluster with different network (supplied by different ISP) between nodes. How can I do this?

What I did not realize was, that DLM uses the external Ethernet Interface even when talking to the local machine/node. So iptables was blocking my DLM daemon. With iptables down or the TCP port for DLM opened, cman starts, mount works.What I have here is a fibrechannel SAN which will be directly attached to several servers in the near future. Thise servers should be enabled access to a single filesystem on the SAN (shared).I heard that the right filesystem choice for this kind of setup would be GFS, because it has a Distributed Lock Manager and one FS journal for each node.
But I am having trouble setting up GFS. I have managed to create a GFS on a small testvolume (local HDD so far), but am unable to mount it. It seems that GFS/DLM needs a lot of cluster services to run, which I do not all understand / know how to correctly setup. Also: Will the lock_dlm stuff need Ethernet communications to handle file locks? And if so, will it fetch the node list from /etc/cluster/cluster.conf to determine who to talk to?

Setting up a linux based church server to be placed with a collocation host.
-- Server will be used for:
--- providing .pdf files
--- live streaming of church services (audio for now audio video soon)
--- providing audio files
--- providing audio-video files
--- our internet web site
A. Is there a preferred Linux distribution that will make this easier?
B. What is the best format for audio and video files that will be viewed variously on Linux, Mac, and Microsoft operating systems? Files will need to be played on older versions of operating systems and may need a free or very low cost software to play (e.g. play on Win2k)
C. What software is best for recording the audio or audio-video files? Some additional funding might be justified for this software, particularly if it can also support live streaming.
D. What software is best for live streaming both on the file creation and the listening-viewing sides of the process?
Ideally we would like to have a single software suite to live stream, and make downloadable audio or audio-video files for later download, and not require those listening and viewing to have to install additional software. Keeping file sizes small is also desirable because some of our users will probably only have dial-up internet.
