Playing DVDs on AMD64 system
by larry_prikockis＠natureserve.org 24 Feb '05

24 Feb '05

Has anyone managed to get any DVD playing software running properly under SuSE 9 for the AMD64? I've got an ASUS K8V Deluxe MB and an NVIDIA GF5200FX video card, for what that's worth. I've been trying, with little success, to compile a working version of the 'Ogle' DVD player, but am running into all sorts of dependency issues with RPMs, and missing library issues compiling from source. If someone else has gotten this working, I'd be interested in hearing exactly what RPMs/source files you used and what steps you followed. Thanks in advance ----------------------------------------- Real programmers confuse Christmas and Halloween because DEC 25 = OCT 31

As far as I know, I'm not 'compiling in' anything other than what the package itself calls for. I did a... ./configure --enable-libsuffix=64 make Is there something I should be doing to 'ease back on the functions'?

The only benchmarks that matters to you are your own. Aside fron that, my benchmarks between 32 and 64 bit systems have shown that I get the best results on each system using code built for those specific architectures. I have 32 bit apps that were simply dragged and dropped into the 64 bit systems with some performance improvements. But the big improvements came when we recompiled our apps using new versions of GCC that supported the 64 bit architecture of the Opterons. For our numerically intensive applications, we saw over 70% improvements over 32 bit systems running at the same clock speed. But there was another cost that affected the throughput. The 64 bit compiled apps would use up more memory, so the memory that was just adequate to support the 32 bit apps would not be enough for 64 bit apps, and the subsequent swapping would make the apps run very slowly, as expected. I think that if you can rebuild your mysql binaries from source on the 64 bit system using the latest GCC compilers, you can gain huge increases in performance as well. eyc

Speed comparisons... amd64 vs em64t?

Speaking of which... Does anyone else have any decent comparisons of more real-world apps (not just synthetic benchmarks) between differing 64bit archs, especially opteron vs Intel? I tossed together a quick set of tests using 'openssl speed rsa' between IA64 and opteron (older 2.4 kernel systems) then amd64 vs em64t on some SLES9 installs (http://www.miguelito.org/openssl) and it looks like amd has a nice lead right now. Would love to see more application comparisons though. -- Mike Marion-Unix SysAdmin/Staff Engineer-http://www.qualcomm.com [It's Halloween Kitty gives out raisins] Kids: "Ewwwww..."

I mean, that for a real test, the database must have many millions of rows. With a database with few megabytes, its\'nt a real test for 64 bits. __________________________________ Registrate desde http://servicios.arnet.com.ar/registracion/registracion.asp?origenid=9 y participá de todos los beneficios del Portal Arnet.

Sles9 ntpd failing to start

Bouncing to this list too since it might be an amd64 thing.. Error: ntpd[527]: cap_set_proc() failed to drop root privileges: Operation not permitted This is on amd64 hosts, google search didn't dig up much.. few mentions of another package, and one ntpd with this, but I didn't see a resolution. Have 30 blades like this.. same hw in a workstation works, though I YOU'd it the other day so it's more up to date then blades... but I YOU'd one of the blades and it's still failing there.

My question is, > - Is hardware RAID worth the extra money in >performance/reliability/etc or should I go with software raid Most of those inexpensive RAID controllers (like the 2 channel types) are nothing more than 2 channel ATA or SATA cards with either hardware or software based RAID0 or RAID1 capabilities. These are either simple striping (RAID0) or mirroring (RAID1). The hardware really doesn't do much in most cases. I think most of them can be configured to present the disks straight to the OS, and let you treat them as regular disks. I am told that configuring RAID0 or RAID1 from Linux can sometimes get better performance out of them than if you let the hardware do the same things. Again, the Linux OS does not have to do much to perform those functions. But my experience is that if one of the drives fail, it's much harder to recover a RAID1 set from Linux than if you had let the hardware take care of the RAIDing. (If you lose a drive in a RAID0 set, you've lost all the data anyway.) The value that a high performance RAID controller gives you is the ability to combine many drives (5 or more) together to provide greater throughput, higher capacity, and redundancy to protect against single drive failures. Such a RAID controller will have a number of features: - Multiple separate disk channels to allow each drive to communicate uninterrupted with the controller. All the new RAID systems using PATA or SATA drives will provide a separate channel for each drive, so each drive becomes a bus master. - A hardware CRC calculator to generate the redundancy code in real-time. Any RAID systems that have to use your CPU to generate the code will be much slower, and sort of defeats the performance aspect of RAID. I am told that the speed of most x86 based processors today may out perform most hardware CRC generators. This may be true, but I still would not want to dedicate my host CPU to processing RAID data. - Some amount of cache memory to buffer host requests. This may be the most important factor for getting good response from a RAID controller. Today's RAID systems can make use of two levels of cache; a large chunk on the controller, and whatever the drives come with. Write requests are usually set up with write-back caching, so host response is pretty instantenous. Without the write-back cache, write requests will have to wait for the actual disk operations to complete. In this case, the more drives there are in the RAID set, the greater the percentage of latency; A write operation from the host will be divided by the number of drives in the set, and the more drives in the set, the smaller chunk of data goes to each drive. But each request to each drive still incurs the same amount of latency. A potential problem with write-back cache is data inconsistency in the event of a power failure. So the RAID systems that guarentee reliability will have some kind of battery backup for the cache in the controller. (But that doesn't do much for the cache in the disks.) Read requests will have to depend on cache look-ahead strategies on the RAID controller. The first of a series of sequential read requests will be slow, as the controller has to wait for seeks and reads from all the drives to complete before handing the data back to the host. Subsequent requests for sequential should be much faster. Some RAID controllers can optimize this with the disk cache. (More than you wanted to know, I'm sure.) eyc

usb drive problem emachines 6811/kernel 2.6.5-7.108-default
by Warren MacEvoy 30 Sep '04

30 Sep '04

When I upgraded kernels I lost my usb drive access. usbview shows it when I plug it in, but it never automounts. Worked fine before the kernel upgrade. I'm new to the usb auto-mounting business, so advice on what to look for would be helpful. Thanks, Warren MacEvoy

Finding my way
by BodellS＠cooleygroup.com 30 Sep '04

30 Sep '04

I am relatively new to linux and suse. i've been running Suse 9.1 on an AMD64 as a guest os under VMWare. We've been testing linux capabilities but keeping windows as main os for windows network admin etc. Well I'm ready to switch to Suse 9.1 64 as host os and put windows on as guest. the problem is RAID. My mother board, ASUS K8V has on board raid which i have been told is not "TRUE" RAID and therfore not supported. So now, I'm considering software RAID or buying an inexpensive 2 channel SATA RAID controller. My question is, - Is hardware RAID worth the extra money in performance/reliability/etc or should I go with software raid - If hw RAID is the way to go, which has driver support for 64-bit linux? Thanks sandy

I currently have a dual 244 machince and a dual 248 machine at my disposal for testing purposses. The 248 machine is load up with a tyan board 64 bit nic, 64 bit sata raid 10 with four 10k rpm hard drives, 2 gig of ecc ram.The Dual 244 is a little more modest with 1 gig of ram, onboard raid 1 with two 10k sata drives. Feel free to contact me if you want me to test anything out, I also have a pair of single CPU opteron 240's, but they are running as win 2003 64 bit domain controllers.
