I don't think cpusets needs to grow beyond what it contains now. The discussion started as an API discussion. Cpusets requirements, current API and usage models were clearly shown. According to Hubertus CKRM will be able to deal with these and implement them in its own API. It isn't today. So why not wait for that? Having two APIs for the same thing isn't unusual. Whether we switch from affinity to sched_domains underneath isn't really the question. > I realise there are technical/architectural problems too, but I do fear > that there's a risk of we-don't-have-a-business-case happening here too. ISVs are already using the current cpusets API. I think of resource management systems like PBS (Altair), LSF (Platform Computing) plus several providers of industrial simulation codes in the area of CAE (computer aided engineering). I know examples from static and dynamic mechanical stress analysis, fluid dynamics and electromagnetics simulations. Financial simulation software could benefit of such stuff, too, but I don't know of any example. Anyhow, I'd say we already have a business case here. And instead of pushing ISVs to support the SGI way of doing this, the Bull way and the NEC way, it makes more sense to ask them to support the LINUX way. > But we're not there yet - we're still waiting for the design dust to > settle. :-) Regards, Erich ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
