Lustre discuss - Oct 2012 - lustre client on arm debian

Hi,
has anyone tried to compile the lustre patchless client on a debian 
linux for arm architecture? Could be possible to do?

Thanks in advance.

Gabriel,
Many years ago, someone was working on a MIPS port for Lustre and I believe they
got it working, but I don''t think the patches ever landed. You could
make a quick search in bugzilla to see what changes they made, and update this
for Arm as well.

Are you looking for client or server support?  My understanding is that Arm is
only 32-bit today.  While we regularly build for 32-bit kernels, this is not
tested automatically on master anymore so it is possible that there have been
regressions in this area.

If be happy to hear your experiences in this area, and it would be a good time
to land any patches needed to make Arm builds working.

Cheers, Andreas

Hi Andreas,
many vendors are going to put in the market ARM+GPU based cluster. Yes, 
ARM is a 32bit system, with now a 1 Gbit connection normally, but in few 
watt could have a performance of 300 GFlops... so I think in the near 
future could be a player in the HPC market.

I''m interested yust for the patchless cluster...

thanks

hello all

an ARMv8 (64bits) simulator is available from ARM, Linaro was ported 
over it recently
It runs a 3.6.0 linux, i did not try to use a Lustre supported kernel on 
it (this will simplify the port)
If it does not work, first you will have to port Lustre client on a 3.6 
kernel

Bye

JC
