Hi Foetz,

Thanks for the update. very usefull to know that also Pirana needs uncompressed pictures instead of direct mpeg/jpeg stuff.

And that can be on either a Fuel or an Octane2, right?
Do you or anyone has experience running Pirana on a Fuel?

Reason is that I need to choose between a 'Fuel@600Mhz with V10 and 4GB' or an 'Octane2@400Mhz with V6 and 2GB'
Drive array will be 1Gbit Fibrechannel type.

I know an Octane can be upgraded to a dual 600 but that is too expensive (even dual 400) and I think there will be also little chance to upgrade the Fuel's CPU too.

Thanks in advance,

Get the Fuel. The bottleneck will often be the gfx. Also, you should get V12 if you want to work with HD. See:

http://www.sgidepot.co.uk/perfcomp_DISC ... Tests.html

Different app, but the same issues apply.

1Gbit FC is not enough for HD. You should be using at least 2Gbit, though I get better I/O results with SCSI
(nobody's beaten my results yet AFAIK, eg. 511MB/sec with Octane).

Ian.

PS. I've been told an earlier version of Pirahna on Indigo2 with 6.2 can utilise CosmoCompress, but haven't
tested this yet.

Hi Ian,

Thanks for the advise, this is very usefull indeed.
What surprises me is that you mention a Fuel being able to run Flame.
I never knew Fuels are capable of running discreet software at all.
Are you sure about this?

Or does anyone have experiense with Fuel and Flame or discreet?

Thanks in advance,

If they weren't capable of running it, I wouldn't have been able to do the tests. All I did was move a Tezro
disk into a Fuel, with the /etc/ioconfig.conf file removed prior to the switch. The Spark test didn't work
though, probably because of how it's installed. A native install would likely fix that. No surprise here IMO,
both systems are the same arch, which is why a Fuel disk can boot a Tezro and vice-versa.

Whether or not it was a supported configuration is a different issue. What my tests show though is that,
overall, a Fuel 600/V12 is a better system for Flame than an Octane dual-600 V10. Why anyone was
using V10 systems is beyond me (really bad idea). Likewise, V12 for Tezro should have had 512MB RAM.

SD results coming later, and both SD/HD tests for Inferno, etc.

Ian.

you're welcome!
anyhow i did not say it MUST be uncompressed. i just never used anything else :D
and yes, octane2 is fine. onyx as well ...

Easy to do if ffmpeg can decode video files from camera

Code: Select all

ffmpeg -i camera_file.avi image%d.sgi

unfortunately neko_ffmpeg-SVN-r6775 is too outdated and does not have sgi image file format

What software would you use for the VINO inputs on an Indy? I was hoping to use my Indy for video editing, even if the quality is low. I've been searching the web but I can't figure out what software was used with it even when the Indy was brand new.

Thanks

There's a FuelV10/FuelV12 licensing option coded into Flame 9 - whether or not they were ever sold is definitely a different story as I am fairly certain they were not.

If you don't need SDI I/Os a Fuel or modified Origin 350 with V12 makes an excellent Flame box, even for HD. If you do need SDI, you should probably get a Tezro as it has enough XIO slots to support both ODYSSEY graphics and SNOWBALL (the DMediaPro SDI I/O option). Two Origin 350s in NUMALink might also be able to achieve this configuration (V12 in one, SNOWBALL in the other), but I have not tested firsthand.
I just shovel uncompressed video imported and preprocessed elsewhere as frame sequences to and from my O350 Flame box, and this workflow works okay for me. I am not a professional user though - just a hobbyist having some fun. I'm using 3 internal disks across my 2 NUMALinked O350 chassis as Stone (via the Stone internal disk licensing method), and I get about 135MB/s which is decent enough for basic tasks. My quad 1Ghz R16Ks absolutely fly, especially compared to an Octane2.

The Fuel is definitely the most economical option (unless you can get lucky on some O350s) - you can generally get a mid-specced Fuel for less than a a comparable Octane2, and the Fuel is quieter and less power-hungry.

I preprocess and convert on another (Linux) box, so it's not a worry :) I do wish we had better ffmpeg support for IRIX and MIPS, both in regards to support and optimization, but it doesn't look likely.

Media Recorder and Movie Maker should have been included with any reasonably complete IRIX install.

If they weren't installed, the release notes for VINO will run you through the process: http://techpubs.sgi.com/library/tpl/cgi ... notes/vino

Hi there! :)

I've recently come across what appear to be original Discreet lics that say HOSTID=ANY. The app regards Fuel &
Tezro to be the same thing, so there you go I guess.


> ... My quad 1Ghz R16Ks absolutely fly, especially compared to an Octane2.

My tests showed the speedups are not as good as one might expect though. CPU scaling is as expected, but other tasks
are badly bottlenecked by the V12. Compare my combo test for dual-400 Octane2 V12 vs. quad-1GHz Tezro V12.

I intend testing Fuel 700, 800 & 900MHz configs, when I can find the time.

Cheers! :)

Ian.

You'll need to either use low resolution or get a Cosmo board, as the Indy 10MB/s SCSI interface can't handle full NTSC resolution video.
Damn the torpedoes, full speed ahead!

Living proof that you can't keep a blithering idiot down.

EDIT: I got errors when trying to run it on my SGI with the same syntax as a newer build on peecee, and compared the source codes later. This old ffmpeg can output sgi files with a different syntax.
