2013/3/8 Paolo P. Martino <paolo@mudra= st.info>
Hello all,

I am studying for a MSc in High Performance Computing at the Edinburgh Univ= ersity, UK.
As part of my dissertation project, I was thinking to use Plan 9 as compute= node for ARM-based clusters.
My idea is to "port" the ideas of Plan 9 on Bluegene to ARM.
I have a couple of questions:
1) How is the status of linuxemu? Does it work only on x86 or is it portabl= e? This because of MPI/OpenMP/FORTRAN widely used in High Performance Compu= ting.
2) Is someone already working to port Plan 9 on Exynos5/Cortex A15 processo= rs?

I'm still checking with my university if I can use this project also fo= r the GSoC 2013.

Thank you for your time,
Paolo P. Martino

I am happy to share this if you want it. I have diverged from cinap's origional a little but for what are (I feel) good reasons. As far as I know it emulates only X86 32bit linux on exactly that platform, I suspose it might work on a 64bit plan9 platform with some work, but I am unsure - cinap will know more. -Steve From mboxrd@z Thu Jan 1 00:00:00 1970 MIME-Version: 1.0 In-Reply-To: References: <23789690-6f72-4a35-a6ca-d11359b59781@googlegroups.com> From: John Floren Date: Fri, 8 Mar 2013 08:33:41 -0800 Message-ID: To: Fans of the OS Plan 9 from Bell Labs <9fans@9fans.net> Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable Subject: Re: [9fans] Plan 9 ARM questions Topicbox-Message-UUID: 25497db0-ead8-11e9-9d60-3106f5b1d025 xcpu is cool, but it doesn't really have anything to do with either of his questions besides being generally related to HPC. I don't see why you couldn't make linuxemu portable, Ron did something similar to run CNK binaries on Bluegene. john On Fri, Mar 8, 2013 at 3:07 AM, Bence F=E1bi=E1n wrote: > maybe it would be worthwhile to look into XCPU: > > http://xcpu.sourceforge.net/ > > > > > 2013/3/8 Paolo P.
