Ask HN: Fedora style version of RedHat RHEL MRG?
Has anyone tried out the Redhat RHEL MRG product? It is a variant of their enterprise Linux distribution with a realtime kernel, optimized messaging based off Apache Qpid, and Condor/EC2 integration. I'm particularly interested in the realtime and messaging components performance relative to the standard enterprise alternatives.
I realize various parts (or perhaps every line) of MRG is available in various ways, but does anyone know of a Fedora style project with the bleeding edge versions all nicely packaged so hobbyists like myself can experiment with the technology? The CentOS guys have MRG on their todo list but it seems there isn't enough demand for them to get to it sooner rather than later.
- jacquesm 17y agoI haven't but I really wished that the realtime patches would be made a standard part of the kernel. Lots of code could take advantage of that. MRG supports MPI, the de-facto message passing interface for clusters, that alone makes it worth looking at. One step closer to QnX... To have the CONFIG_PREEMPT_RT patch in stock kernel would be very nice. A real-time kernel is not just for people controlling machinery. If you are going to spend time on this will you please do a write-up of your experiences ?
- linuxconvert 17y agoI'd be happy to - though I guess I'll have to get one of those "blag" things the kids talk about. I'm also pondering SUSE's real time extensions. They at least make it easy to get a trial version of their enterprise distribution plus a trial version of the real time extensions to install on top. Redhat of course have a 30 day trial of RHEL but not, as far as I know, of MRG. 30 day trials aren't ideal - I have no intention of going into production without a real license but it'd be rather useful for educational purposes to be able to experiment without a timed trial (especially when hacking in the evenings only on it).
