[BProc] bproc-4.0.0pre5 - something works but not quite

[Michal J. <mi...@ha...>]

I am trying to get bproc cluster running on 64-bit Opterons with
a kernel based on 2.6.6 and patched up bproc-4.0.0pre5.  Front end
is running Fedora Core 2 distro plus support.  That
hardware/software combo seems to limit my choices to that bproc
version.

I have one client node so far.  At this stage I can boot a node
and I see from it
....
nodeup    : Node setup completed successfully.
nodeup    : Node setup returned status 0

although 'nodeinfo' tells me "cpus=0; hz=0; mem=4163420160" (which
is hopefuly minor).  Also 'bpstat' prints:

0                                  up              ---x--x--x root     root

So far so good.  But if I will try, say, 'bpsh -a ls' then I end up
with "bpsh: Child process exited abnormally" and on a monitor hooked
up to a node I see lines like that:

ls[199] general protection rip: 3a1cd0ada7 rsp: 7fbffff010

OTOH bpstat seems to work fine so I can power down a node, or change
it ownership, but that is about it at this moment.  Any ideas?
