EXCHANGE 2010: An error caused a change in the current set of domain controllers

 

 

After some digging in the profile, I found out the following file, which seemed to be the cause of the problem:

c:\users\<specific user>\appdata\roaming\microsoft\mmc\Exchange Management Console

 

Rename or delete this file, restart the EX2010 EMC and all errors will be gone.

Outlook 2010 HTML break blue citation line

Coming from Outlook 2003 everyone knows that one can break the blue line marking the cited text  by entering a new text or at least with the common reverse indent button. This does no longer work for Outlook 2007 and 2010 as the blue line is now represented in some different way.

You can get around this by Ctrl+Q but  if you check the email at the recipients mailbox, you will see the unbroken blue line again.

If you switch to Rich Text you can actually use Ctrl+Q and it will be that way at the recipients side too.

If you have a real solution to the html problem, please comment!!!!

 

Please refrain from any unfeasible comments about the sense and non-sense of HTML mails. For that a lot of forums are available online to take that garbage!

OpenCL programming

OpenCL Kernels get compiled at execution time (Just in Time, JIT).
This means that any error inside the kernel is discovered at that time.
The error message I get till now are very silent about what the problem of the kernel is.
So there is just one method of commenting and uncommenting to get a kernel debugged just for compilation.

Intel however recently released it's first beta version of OpenCL with a lot of tools.
As with early Parallel Studio, these tools are only available for Windows (in particular Win Vista + and Server 2008) and not for Linux.
Note, that the runtime for compiling and running OpenCL is available for Linux, Mac and Windows!

Included is the Intel OpenCL Offline Compiler where you can load your kernel and precompile it.
Here the error messages are much more helpfull (of course, helpfull in a way ordinary compiler messages are helpfull :-)).
Nevertheless, a great tool which makes daily programming a lot easier.

OpenCL GPU computing tutorial

Very nice tutorial with hands on about installation, setup and programming:

NVIDIA CUDA disable/enable ECC , new commands

In order to query ECC status in CUDA 4.0 (and hopefully the next versions), nvidia-smi works a little bit different:

nvidia-smi -q | grep -e"Ecc Mode" -e"Product" -A2

will give you a excerpt.
Just use nvidia-smi -q for full output



To enable ECC:

nvidia-smi -i 0 -e 1


To disable ECC:

nvidia-smi -i 0 -e 0

Where i is the GPU ID!

TinyGPU upgrade to CUDA Toolkit 4.0

All nodes of the TinyGPU Cluster is now on the current CUDA Toolkit 4.0 and the appropriate driver.

GIT: Compare/Diff working directory against server/repository state

git fetch --> updates your local rep but not your working Dir
git diff ... origin gives you the comparison

GIT: Ignore File mode/right changes

If you have files or directories under git control and change the rights of them, git does recognize them as changed.
To force git to ignore these changes just execute the following.

git config core.filemode false

You can reenable that after all files have a new revision because of an actual change and are comitted in the new mode anyway.

LIKWID: Installation Hint

If you set the likwid install path in config.mk and the last character is a slash, likwid-pin will not run with the following error message:


ERROR: ld.so: object '~/helper/likwid-2.2-inst' from LD_PRELOAD cannot be preloaded: ignored.

Delete the last slash and do
make clean && make && make install

and likwid-pin should work fine.
