RE: nodebytes and leafwords
hi kuhlen,
what you said is correct. i am talking about how
you are going to arrange these codewords into an
array, i.e. in the function _make_decode_table.
there he uses node bytes and leaf words for memory
management. i got a 24 bit platform. so if i assume
that max. codeword length that could be possible as
24 bits can i allocate a memory of (2 * used entries - 2),
to arrange the whole tree in

[LLVMdev] Crash in PBQP register allocator
Hi Sebastian,
It boils down to this: The previous heuristic solver could return
infinite cost solutions in some rare cases (despite finite-cost
solutions existing). The new solver is still heuristic, but it should
always return a finite cost solution if one exists. It does this by
avoiding early reduction of infinite spill cost nodes via R1 or R2.
To illustrate why the early reductions can be a

Is NUMA working correctly?
Hi Everyone,
I''m trying to bind CPU and memory usage to particular cores using some
Quad CPU 16 Core Opterons. They have 64GB RAM, 16 GB per node. It seems
that xm info shows it is not working as expected though, below are
details for the first node:

[PATCH]: xl: fix broken cpupool-numa-split
Hi,
the implementation of xl cpupool-numa-split is broken. It basically
deals with only one poolid, but there are two to consider: the one from
the original root CPUpool, the other from the newly created one.
On my machine the current output looks like:

echo 0 > /proc/sys/kernel/hung_task_timeout_secs and others error, Part II
The first problem is as below:
One issue is the files copied to the device but it can't be list on node2, using ls -al the mounted directory.
But using debug.ocfs2 on node2, it is ok to list the files copied. After remount of the device on node2, the file can be list.
The second is that:
Node1 is in the ocfs2 cluster, but using debug.ocfs2, and mounted.ocfs2 -f command, can not list the node1

Speed issue in only one direction
Hi all,
I'm back again with my speed issues. The past issues where dependant of

Now I run my tests in a lab, with 2 configurations linked by a Gigabit

Both have AES and PCLMULQDQ announced in /proc/cpuinfo.
I use Tinc 1.1 from Git.

Why is cpu-to-node mapping different between Xen 4.0.2-rc1-pre and Xen 4.1-unstable?
My system is a dual Xeon E5540 (Nehalem) HP Proliant DL380G6. When
switching between Xen 4.0.2-rc1-pre and Xen 4.1-unstable I noticed
that the NUMA info as shown by the Xen ''u'' debug-key is different.
More specifically, the CPU to node mapping is alternating for 4.0.2
and grouped sequentially for 4.1. This difference affects the
allocation (wrt node/socket) of pinned VCPUs to the

Re: NUMA issues on virtualized hosts
Hello,
ok, I found that cpu pinning was wrong, so I corrected it to be 1:1. The issue
with iozone remains the same.
The spec is running, however, it runs slower than 1-NUMA case.
The corrected XML looks like follows:
<cpu mode='host-passthrough'><topology sockets='8' cores='4' threads='1'/><numa><cell cpus='0-3'

[LLVMdev] Nice nodes dumping patch
Hi all. Currently if you launch some tool with "-debug" option, you got
pretty detailed dump. Though the SelectionDAG nodes will dumped as its
pointer values:

0xa1d7368: i32 = undef [ORD=1]
0xa1d73f0: i32 = TargetConstant<12> [ORD=1]

It is good if you want to look at memory contents by its address then.

The error they receive is "currently no logon services available"
this is very odd, because i have 2 samba 3.5.8 servers available, running

different uuids, but still "Attempt to migrate guest to same host" error
Background:
----------
I'm trying to debug a two-node pacemaker/corosync cluster where I
want to be able to do live migration of KVM/qemu VMs. Storage is
backed via dual-primary DRBD (yes, fencing is in place).
When moving the VM between nodes via 'pcs resource move RES NODENAME',
the live migration fails although pacemaker will shut down the VM
and restart it on the other node.
