Hi Ralph,
There is an MCA param that tells the orted to set its usage limits to the hard
limit:
MCA opal: parameter "opal_set_max_sys_limits" (current
value:<0>, data source: default value)
Set to non-zero to automatically set any
system-imposed li

Isn't it possible to set this up in torque/moab directly? In SGE I would simply
define h_vmem and it's per slot t
I have various boxes that run openmpi and I can't seem to use all of
them at once because they have different CPU's (e.g., pentiums, athlons
(both 32 bit) vs Intel I7 (64 bit)). I'm about the build 1.4.3 and was
wondering if I should add --enable-heterogenous to the configure flags.
Any advice as
I'd like to add to this question the following:
If I compile with --enable-heterogenous flag for different
*architectures* (I have a mix of old 32 bit x86, newer x86_64 and some
Cell BE based boxes (PS3)), would I be able to form a MPD ring between
all these different machines?
Best regards

Hetero operations tend to lose a little performance due to the need to
convert data, but otherwise there is no real negative. We don't do it by
default solely because the majority of installations don't need to, and
there is no reason to lose even a little performance if it isn't necessary.
If you
The short answer is "yes". It should work.

Ralph, thanks for the reply.
If I build with enable-heterogeneous and then decide to run on a
homogeneous set of nodes, does the additional "overhead" go away or
become completely negligible; i.e., if no conversion is necessary.

I'm no expert, but I think the overhead d
