SUSE Linux Enterprise Real Time 10
Might someone know the specifics of what this really is. The web site is vague. I'm interested in knowing if the kernel used is based on Ingo Molnars -rt patch set and if its glibc has PI enabled mutex support (2.5). Is it anything more than SLES-10 with these 2 things. If the kernel is based on Ingo's -rt patch set will they possibly be including this support in SuSE-10.2 kernel? Can anyone already using Beta 10.2 releases say if their kernel source config options include a "Complete Preemption (Real-Time) (PREEMPT_RT)" in the "Processor and features" section? Thanks Mark

Might have better luck with and possibly a response from a SUSE engineer on the opensuse-factory list. You can subscribe by using opensuse-factory-subscribe@opensuse.org. Stan

SLERT is more based on Concurrent work, not Redhat. 10.2 uses the 2.6.18 mainline kernel + some small patches. Ciao, Marcus

I saw the announcement for this a while back and was intrigued. It was targeted for things like stock market work. I am curious if this will ever find itself in a purchasable product geared to smaller system users. I for one would be interested in paying for this if the price was right. RT and all the SUSE stuff in one package would be a good thing. I fear it is targeted as a high-end thing. -- Roger Oberholtzer OPQ Systems AB Ramböll Sverige AB Kapellgränd 7 P.O.

I can't really say because I just do not know much, but as far as I know ... it is more for a high-end market right now. Ciao, Marcus

I've had a chance to look at this in some detail. It is in fact not using Ingo's rt patch set and does use another on top of what appears to be SuSE's kernel that shipped with SuSE-10.1. This other patch set includes some things that are also in Ingo's (HRT, PI, etc.) but has some unique things. It also has Concurrents IDE which is claimed to be pretty nice. When loaded on top of SLES-10 no already built applications will benefit from the added hooks to its kernel or glibc. In order to get any Real-Time response you have to write your program using their API via their library using hooks into their kernel. I haven't actually tried to write or modify a program to test the accuracy of their <= 30 usec latency claims yet but I have my doubts. Here is the one I will use though. ftp://ftp.compro.net/public/rt-exec/rt-exec-1.0.3.tar.bz2 Mark
