 Yes, and we are working on fixing those issues in EL6.6.  So perhaps when 
 EL6.6 is released you will be able to use the OS packages.
 Rich et al,
 
 I've been following this thread with interest.   I am however a little 
 confused about the right place and version to get 389:
 
 you make a distinction between the source version (versions 1.2.11.28 and 
 1.3.1.16).  Both are stable, 1.3.1 is just newer and potentially more 
 bleeding edge?  1.3.1 also seems to not be available from either the OS or 
 epel repositories.
 
 1.2.11 branch is strictly maintenance - only the most critical patches.
 
 1.3.1 branch is less strict - it may get new features.
 
 1.3.1 is available for Fecdora 19.  1.3.1 will be in EL7.  We are not 
 planning to provide it in EPEL7 at this time.

Thanks, that makes sense.

 
 And if epel6 contains patches that have not been fully tested and I should 
 avoid it in production but how do I get the admin server, console etc?
 
 There is a distinction between epel6 and the official EPEL6.  What we call 
 389-ds-base in epel6 is not really the official EPEL6 repository.  It is 
 an individual developer provided and supported fedorapeople (and now copr) 
 repository strictly for those who want to (or must) be on the bleeding edge 
 of the 1.2.11 branch - those who absolutely require bug fixes or features 
 that are present in the upstream 1.2.11 branch, but are not yet in the 
 official EL6.5 389-ds-base package.

I understand.   I didn't catch the distinction between EPEL6 and epel6.  

Where is the (lowercase) epel6/copr repository?   I know I've seen the fedora 
people repository in the past but I can't for the life of me find it (or copr) 
now.  I see various pages but not the repository itself.

thanks for the clarifications,

Hi all,

I reaqlize that the info I'm giving here might be to little to give any
good suggestions, but I'm giving it a try nevertheless. I have a MBP with
the following graphics card:

VGA compatible controller: NVIDIA Corporation GK107M [GeForce GT 650M Mac
Edition] (rev a1)

I have no problem connecting to a second screen (VGA, Nouveau), but when I
connect to a projector (VGA) it doesn't show up at all. No, I don't have
the models of the two projectors I've tried with, but I did have the same
problem with my other computer and Fedora 15 (that time I was running
NVIDIA drivers).

Am I missing something obvious here? I wasn't clever enough to look at
Xorg.0.log yesterday when I tried the projector (I've been looking through
it now but I can't seem to find the right place), but I will next time and
perhaps I can provide better information.

Best,
/Henrik





What version of Fedora are you running?

On a PC, I just plug the projector in and it works in F18, F19 and F20.

Is the Other computer a MBP as well?

I wonder if there is some hardware issue that is being a pain if the 
monitor works and you unplug the monitor and then the projector and it 
doesn't without a reboot.  Something that is detecting the projector and 
blocking the port.


A quick scan of the web shows that this is also a problem for people 
using just macs.  You may need special drivers for the mac.

As for the answer to your initial inquiry i would highly recommend ROCKS
Clusters that is based on CENTOS. it will automatically install and

I have tried ROCKS before (granted it was maybe 6 years ago) and it 
seems good if you have very lage number of nodes. If not then I would 
recommend setting the things yourself. Most programs run in scientific 
clusters use MPI for shared communication so you will just need MPI 
setup I would not waste time job management and such as long as there is 
only one person running on the cluster.


Setting up maybe 10 to 20 machines with kickstart using fedora with 
openmpi, ssh-keys for easy access to nodes and nfs sharing form frontend 
shouldn't be that big job. You will take same amount time learning ROCKS 
and it will have lots of features you don't need.


Also if you don't use the machines all the time and don't have the 
hardware yet it might be beneficial to use AWS nodes to do the 
calculations. In big HPC setups the real cost of the cluster usually 
comes from electricity consumption and cooling so you should factor 
these costs in when deciding what to do.

 Quite possibly GDM only lists the new sessions when it starts, so try
 either restarting GDM (systemctl restart gdm.service) or rebooting.

 Everything necessary to start the session is in the kde-workspace package.


 yum install @kde-desktop

 solved my problem.


IIUC, installing the KDE Plasma Workspaces group should have
installed the kde-desktop group (among other mandatory groups).

 I have tried ROCKS before (granted it was maybe 6 years ago) and it
 seems good if you have very lage number of nodes. If not then I would
 recommend setting the things yourself. Most programs run in scientific
that would sum to: set up common authentication, common logging,
monitoring, nfs shared home (optional but very useful), the resource
manager and individual management of settings and packages of each
worker node. But this is up to the admin preferences (i use a personal
cluster with 4 nodes (32 cores) and from my point of view it saves me a
lot of time instead administering each node by hand) (it takes 10
minutes to re-install all nodes with different settings and new updated
packages) (for the 40 nodes grid cluster it takes the same 10 minutes ;) )

 clusters use MPI for shared communication so you will just need MPI
i dont know what is meaning of most .. in my world of high energy
physics we use only distributed computing (so no MPI)

 setup I would not waste time job management and such as long as there is
 only one person running on the cluster.
you might (i am sure you will) be hit by a lots of problems .. mpi does
not have a knowledge of nodes and their capacities nor about their
availability and status. also if you need to start multiple parallel
jobs  (eg. you have a 32 cores cluster. a job (on all 32 cores) will
take 16 hours to complete. if you launch in the morning at 8 am, the job
will will end at 0:00 so until the next morning the cluster will just
sit idle) you will need a resource manager.

 Setting up maybe 10 to 20 machines with kickstart using fedora with
 openmpi, ssh-keys for easy access to nodes and nfs sharing form frontend
 shouldn't be that big job. You will take same amount time learning ROCKS
 and it will have lots of features you don't need.
this is dependent of the previous experiences .. i use rocks without
problems .. but i am using it for almost 10 years... YMMV

 Also if you don't use the machines all the time and don't have the
 hardware yet it might be beneficial to use AWS nodes to do the
 calculations. In big HPC setups the real cost of the cluster usually
 comes from electricity consumption and cooling so you should factor
 these costs in when deciding what to do.
I cannot agree more! the advent of cheap IaaS clouds brings a lot of
useful opportunities :)

2014-04-04 Thread Henrik Frisk
Hi,

I'm unning Fedora 20, sorry I missed to put that in. Yes, my current laptop
is also a MBP. Now, I did do a couple of reboots and tried both VGA and
HDMI (mainly to make sure the projector's VGA port wasn't faulty, it is
still connected to the display port on my laptop). I will look into the
question of drivers. It seems to me that quite a few have had similar
problems, also with PCs but you might be right that it is a Mac issue. I
will check to see if I can figure it out.

 What version of Fedora are you running?

 On a PC, I just plug the projector in and it works in F18, F19 and F20.

 Is the Other computer a MBP as well?

 I wonder if there is some hardware issue that is being a pain if the
 monitor works and you unplug the monitor and then the projector and it
 doesn't without a reboot.  Something that is detecting the projector and
 blocking the port.

 A quick scan of the web shows that this is also a problem for people using
 just macs.  You may need special drivers for the mac.

  But with the side panel off, air goes the easiest route that it
 can, and some parts of the board can roast because air isn't

in what i would estimate to be at least 90%, if not 99%, of fans
set up by oem, fans flow air out of the case, not into case. as
such, there is very little airflow distributed anywhere near what
could be considered properly across board and components.

kind of like oems know that airflow is not adequate and they are
hoping for heat failure so they can sell newer and more systems.


I rather like the newer cases that have a big, slow, quiet, fan,

yes, mounting fan on side panel is better as it does allow for a
larger fan. as for speed, i am hoping that the new fans are
variable speed and controlled by temp sensors around memory and
vlsi chips to increase fan speed when needed.

sensors is a great routine that many need to learn to use.

tho i do wonder about it sometimes and now is one of them.

as above, not everyone wants to restart with previous tabs.

besides, Bookmark All Tabs... does give one ability to build

  2) Do a contrast enhancement method called histogram equalization on that

  Let's say that this process involves 500 high-level instructions.
  
  3) Move to the next pixel.  Do the same thing.
  
  If you have a 12-megapixel image (say, 11,760,000 pixels), that's 
  5,880,000,000 instructions.  That 500 instruction block is impossible to 
  parallelize well.  However, each pixel is independent, so you can 
  parallelize the work on each pixel easily.  I remember back in the 80s 
  implementing this on a microVAX GPX II.  It took about 3 hours to do a 
  512x512 greyscale image by brute force.  Then Henry Fuchs et al. developed 
  the PixelPlanes machine, and Austin et al.  implemented it on that -- it 
  took about 4 seconds.  Even today on my laptop with an i7, a brute-force 
  contrast-limited adaptive histogram equalization on a 10 megapixel image 
  takes a go get a cup of coffe time period.  There are, of course, short 
  cuts such as the Pizer-Cromartie algorithm, but they introduce 
  interpolation artifacts.
 
 
 Sure, that's a good example of something that could benefit from
 parallel processing. But you still have to be careful. For instance,
 suppose you do have two different processors working on adjacent pixels
 in parallel. At some point, one of the pixels will be modified first.
 Depending on exactly when that happens, it can affect the final value of
 the second pixel, depending on whether the original or modified value of
 the first pixel is fetched when calculating the second. If done blindly,
 without any locking, this creates a race condition that will cause the
 final value of the two pixels to be indeterminate. That is to say, run
 the same code multiple times, and you might not get the exact same image
 out of it. 
 
 There are certainly tools that would make it easy to distribute the same
 calculation over all the pixels of the image to multiple processors. But
 those tools will not magically provide the locking you would need to
 prevent one of the neighboring pixels from being modified while the
 value of one pixel is being calculated. And the locking code can be
 tricky, which is why it can't be completely automated. For instance, it
 would be easy to lock all the neighbor pixels while calculating the
 value of one pixel. But that would cause the calculation the neighboring
 pixels to be delayed, thus losing some of the benefit of
 parallelization. 
 
 In practice, that example would probably be handled by using a temporary
 array to hold the output image so that the input image is never modified
 until the calculation is completely finished, then copying it back into
 place. But if your code doesn't already do that, it would have to be
 modified to do it that way. Another trivial example to illustrate the
 point.
 
 There are, in fact, tools that can analyze code and point out constructs
 that might prevent parallelization, or suggest places that could benefit
 from parallelization, but use of those tools is not 100% automatic and
 the ones that are used here are (I believe) proprietary and not cheap. I
 don't know if there are similar open source tools, but in any case,
 these tools provide suggestions, but they don't change the code for you.
 It is unlikely that any significant calculation could be parallelized
 with zero work.
 
 For our users, the investment of time in parallelizing code usually pays
 off, because this will help their big simulations run much faster, thus
 saving them time in the long run. We actually have a User Services
 section which employs people who specialize in helping users write and
 modify code to maximize performance on our massively parallel
 supercomputing system.

Rendering (AFAIK) doesn't really require the tight interconnection and
coordination of processes that generally characterizes HPC.  You can
parallelize trivially by treating each frame as a single job--the work
per frame is small compared to the whole job, and each frame is 
independent of the others, so you'll get near perfect speedup that way.

We usually call this type of load (lots of relatively small, 
independent tasks) high-throughput computing (HTC).  One HTC tool 
is HTCondor (Fedora 20 RPM currently condor-8.1.1-0.3.fc20.x86_64.rpm, 
more info at http://research.cs.wisc.edu/htcondor/).  HTCondor manages 
the submission of large numbers of independent tasks to distributed 
computers and the collection of results.  It also manages the load on 
machines that are used interactively, harvesting idle cycles but not 
interfering with interactive use.

 Quite possibly GDM only lists the new sessions when it starts, so try
 either restarting GDM (systemctl restart gdm.service) or rebooting.

 Everything necessary to start the session is in the kde-workspace

 yum install @kde-desktop

 solved my problem.

 
 IIUC, installing the KDE Plasma Workspaces group should have
 installed the kde-desktop group (among other mandatory groups).

Issue is being tracked here:
https://bugzilla.redhat.com/show_bug.cgi?id=1084445

Indeed, it seems yum treats kde-desktop-environment (of which kde-desktop is

 tabs, i can go fix myself a martini while waiting.

   so ... what can i do to debug this? i'm using a non-debug kernel, i
 have nothing else of any significance running, top doesn't show
 anything else hogging resources ... so now what?

   if i recall correctly, fedora 20 worked just fine, while i wouldn't
 wish fedora rawhide on someone holding me up at gunpoint.

   please ... thoughts?

Must not be a general problem since.

[egreshko@f20kde ~]$ cat /etc/fedora-release
Fedora release 21 (Rawhide)
[egreshko@f20kde ~]$ rpm -q firefox
firefox-28.0-3.fc21.x86_64
[egreshko@f20kde ~]$ uname -a
Linux f20kde 3.15.0-0.rc0.git7.1.fc21.x86_64 #1 SMP Thu Apr 3 01:09:55 UTC 2014 
x86_64 x86_64 x86_64 GNU/Linux

And all is running just fine for me.  I think others have said the same thing 
on the testing list where this issue should be addressed.

I suppose you've already tried creating a new/clean user and have the same 
problem?

as mentioned, have you tried a new profile?

SWAG #1. have tried removing current firefox installation
and installed rawhide or earlier version?

SWAG #2. open Browser Console ctrl+shift+j,
select [Clear] button, restart firefox, try opening tabs,
after they open, ctrl+shift+j to see if anything shows.

 not everyone wants to restart with previous tabs.

Yes, sometimes you stopped browsing because one or more websites brought
the thing to its knees, and you don't want to resume that.  

Some browsers have a menu option to resume previous browsing session.
So, after you've started a fresh browsing session, you can use that
option and pick up from where you left off.

Bookmarking's all very well and good, but it's easy to amass so many
bookmarks that you can't make head nor tail of them.  It's not helped by
websites with useless page titles.

CPU / GPU fan control

2014-04-04 Thread Raf Roger
Hi,

i didn't get any answer regarding the FAN control of my CPU/GPU to avoid it
to run at 100% all the time, when i'm just watching a movie or reading on
internet.

where can  find some good information about it ?
i read something about powersaving tool with thinkfan but i don't know why
it doesn't seem to work...and powertools are terminal commands as far as i
understood.

so have you already solved something like that before ?
does it really work ?
thx.

The flash plugin is infamous for doing this.
