I am taking a parallel computing course at school and will be required to write programs using MPI soon. All of the school servers have Lam/MPI installed on them but I can only find OpenMPI slackbuild scripts. If I install OpenMPI on my computer and do my development on my own machine, will I have much trouble when it's compiled/run on the school servers?

View 2 Replies View RelatedI installed the proprietary fglrx drivers, and they didn't really do anything other than break half my software or make it slower. Now the first time I installed the .run binary by just doing 'sh ati-driver-installer-10-3-x86.x86_64'. Then, after Google'ing on how to remove it, I just did 'rmmod fglrx' outside of X and deleted all the kernel modules manually. And that seemed to fix a few things, but not all.
Then I found another thread saying just turn the .run into a pkg, do installpkg, and removepkg, and I did that as well. It fixed most of the problems and seems to have deleted all traces of the fglrx ATI driver.Now, though, anytime I try to run anything 3D, like glxgears, instead of just giving me a segmentation fault, it says:
Code:
glxgears: error while loading shared libraries: libatiuki.so.1: cannot open shared object file: No such file or directory I've Google'd but nothing related came up, Also I can post my xorg.conf file but I don't think that is the cause of this, because I ran 'xorgsetup' and messed around with it some, and it was doing this even before I ran 'xorgsetup' and after I ran it / modified it.
I find problem when run MPICH2 (also Openmpi) on the newest issue of centos-5.6 prerevious I tried MPICH2 on Centos 4, there is no such problem. My procedure is as follows: I built a Bewolf Cluster between 6 nodes of our serve (HP
Proliant G460 G7), and installed the MPICH2 on one node (assuming at /mirror), ./configure --prefix=/mirror/mpich CC=icc CXX=icpc F77=ifort FC=ifort make 2>&1 make install 2>&1
using NFS, the directory of /mirror was successfully exported to the rest of 5 nodes. Now as I test the mpirun, it runs very well on a single node, however it hangs across multiple nodes. Also I have built the passphraseless ssh-keys connection between each other. Now the problem is that even I use the mpd, boot the nodes(those nodes are in the list, and there is no warning during the booting), however when I run the mpirun, whatever how much n (-n X)I set, all the process will be run at the local nodes. I am not sure what are blocking the data exchange between the nodes, by the way, I have set the iptables to accept then data.

View 1 Replies View RelatedI'm trying to get OpenMPI (a parallel programming library) working on my home system. I have just two machines on it now, t61 and quad, connected through a router. (Which is also connected to cable modem for internet.) I can ssh between the machnes, mount directories with NFS, etc. However, I just can't get the OpenMPI to run. The OpenMPI message board suggested that the most probable cause is that the firewall is blocking TCP. I don't know how to tell if that's the problem, and can't find any manual for the SuSE firewall, while the various Wikis &c that pop up in a search don't provide any information that addresses my problem.

View 2 Replies View RelatedI am looking for a kind of update-alternatives for Slackware to set default applications. Currently the reason is I want to use "display" as the picture viewer in Midnight Commander. Display is a part of ImageMagick. "MC" keeps looking for something called "GQVIEW", which is not installed, and is now known as "Geeqie". I removed the Geeqie pkg to see if it would help MC use Display. I also added a line in .bashrc like "VIEWER=/usr/bin/display" to see if it would force the issue.

View 1 Replies View RelatedI am using Fedora 13 64bit on Dell Vostro full 4GB RAM system with default Gnome GUI.
This is very annoying problem that I don't how to fix except by rebooting the whole PC.
When I have too many applications running ( like browser windows), the system start acting sluggish. The fist symptoms appear in Eclipse IDE which becomes so terrible it just becomes frozen for sometime one whole minute after I try to edit something in the editor. Then Firefox seems like it has crashed. Google Chrome becomes very unresponsive as well. All GUI applications including File manager becomes unresponsive.
When I check System Monitor, the CPU is still around 20% and memory is at 80% but the system seems getting fried up. This progressively becomes worse until I soft reboot it or if I dont do it evetually the whole system is fried, no response to any keyboard key or mouse and I have to hit the hardware turn off button.
I regularly yum update the system but this makes no difference.
Please don't tell not to run too many applications because I need those for my work. I thought Linux is well designed Operating System but I am very disappointed so far.
All my applications seem to be running at nice of 19 except bash and daemons which are running at 0. My understanding is that the default nice value is either 0 or 10 (forget which) but not 19.Ran search in /etc/sysconfig/ editor and no results for "nice" and looked at the bashrc files and again no lines contain "nice".

View 2 Replies View RelatedAs a long time Windows user, I am stuck on the basics of installing and running downloaded Linux applications. I've tried to read a few tutorials but am still baffled. I am using a Puppy based boot CD and, of course, the applications that come with the Puppy all work fine. It is when I try to add something new that I become lost. Example: I just downloaded a Linux version of the Firefox browser.
I click on the downloaded file in the Download Manager and kinda expect the thing to give me a executable set-up file, but just get a whole bunch of files. One available option is to "extract" them. I create a folder to extract them to and "extract". With Firefox I see nothing in that folder. With a few other applications, I see an extracted list of files but and try to find one file that will magically start and install or boot an application, but nothing ever happens. So, how does one download , extract, install, and then run a basic application? The references I have found on the Internet tend to be rather old or more complex that my brain can handle.
I've installed openMPI-1.4.1 on my laptop and I'm trying to compile some fortran code I've written using MPI. I downloaded the openMPI-1.4.1 file from the openMPI website and used the shell script they provide to install it. This is the shell script:
shell$ cd openmpi-1.4.1
shell$ ./configure --prefix=/usr/local
shell$ make all install
There was an additional line extracting the tar file, but I did this by hand. The first time I ran this script there was an error on the final stage saying that a directory couldn't be created because of lack of permission. I decided to run the script again this time as a sudo.
Having run the script again everything appeared to install properly, however when I went to compile some fairly simple code I got a message saying that the compiler couldn't find MPI. I was using this command: gfortran messages.f90 -o messages I looked on the openMPI website where it recommends compiling with a compiler called mpif. However when I type mpif messages.f90 -o messages I get an error message saying mpif isn't a recognized command......
When we start some applications like skype though we close it , it will minimize into the panel, another one is amarock that will not quit the application . But now I am not able to see the icons.

I am trying to run the KDE3 version of Basket in KDE4. The KDE4 version is very buggy. I am running Arch Linux with KDEmod. The problem it seems is that Basket tries to connect to the DCOP server but fails, and then crashes. Of course DCOP is only in KDE3 and not in KDE4. So how do I go about running Basket?
Here is the output from the terminal:

DCOP is installed with the KDE3 dependencies. How do I properly run an app that requires DCOP? Or is there another workaround?
My requirement is to save files before shutting the Linux machine down, unattended ie: when the user is not near the machine. This is done whenever the UPS battery is about to die, so that the files get saved. open-Office/text-editor applications that can be saved using keystrokes will have to be found from the running processes and keystrokes should be sent to them from a C program that was started in non-graphics stage. ie: from a C program that forks into memory as a daemon before xwindows part starts. How to I send keystrokes to a running application? (like cotrol + F and then wait and then send next set of keystrokes till the file is saved as a new file or as the same file itself), either from C program or a script?
