I have installed OpenMPI from ubuntu repository. However some users need openMp. The problem is I didn't find that in ubuntu repository. Where can I found deb packages? If I must install from source, then is there any conflict between openMp and openMPI?
View 4 RepliesI have a program that uses both Pthreads and OpenMP. Basically, 2 threads (Thread A and B) are created using Pthreads to do work, and in Thread A, OpenMP is used to parallelize a for loop.If I have a global variable that is accessed by the OpenMP threads and also Thread B, can I use the lock in OpenMP to ensure I have no race conditions?
View 2 Replies View RelatedI am running Yellow Dog Linux release 6.2(Pyxis) on my PS3. I would like to compile and run C programs that utilize OpenMP for parallel programming. Unfortunately, I have not been very successful. I am able to compile programs containing OpenMP statements error free, but when I attempt to execute the binaries I receive the following error: Code: ./file: error while loading shared libraries: libgomp.so.1: cannot open shared object file: No such file or directory Compiling programs without OpenMP statements works fine.
Because it has to do something with missing libraries, I am not sure if knowing the executable search paths may help in diagnosis, but when echoing the path environment variable:

The version of GCC on this machine, 4.1.2 20080704 (Red Hat 4.1.2-44), is identical to the ones I have on two other machines (CentOS release 5.3 (Final) and CentOS release 5.4 (Final)) and they both compile and execute OpenMP code flawlessly. I have tried building and installing another version of GCC that would possibly include the OpenMP libraries, since, according to some sources, GCC has only supported OpenMP since version 4.2. But I have not been successful with that either (that problem would make a good second thread.)
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.
Where can I find the rpms for OpenMP for SciLinux 5.5 for64bit computing?

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 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 9 Replies View RelatedI'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......
I have a bunch of .u1conflict files, and I removed the files having incomplete content and renamed some conflict files to remove the extension. However, the conflict files recur.

Just did a fresh install of Kubuntu 10.04. I use Gedit as my primary text editor. When I was running 9.10, I was able to map shortcuts in Gedit for code snippets and use them without any problems. Now, in 10.04, when I map shortcuts in Gedit, as expected my WIN key is recognized as SUPER (which is how it was in 9.10). But for some reason, KDE now has that key mapped as META. Which means I can set the correct shortcut in Gedit, but can't ever use it because KDE seems to think there is no SUPER key.
I've tried every conceivable option in System Settings > Regional & Language > Keyboard Layout > Advanced > Alt/Win Key Behavior. Nothing works. I've also tried various combinations of enabling/disabling keyboard layouts altogether, and switching keyboard models. No luck so far... What's so mind-boggling is that this all worked flawlessly in 9.10. I must've screwed something up recently, but I have no idea where to look...
After a long time of happy Skyping, I now seem to have picked up a conflict. When I try to open Skype 2.1 Beta which is the one on Ubuntu that I have been using, the login fails. The message is that there is possibly another version of Skype already in operation. I went to the Skype site and changed my password, then I connected via the Skype website, no problem, but with straight Beta. This works fine, but when I exit Skype, I have to re-connect via the website again, the version on my system is unable to connect, apparently due to the presence of the other version.
View 5 Replies View RelatedFrom time to time I have to close Opera in order to regain the ability to use Totem or VLC (perhaps others). I'll explain. Normally everything is fine, but from time to time I will open Movie Player (Totem) and it will attempt to load whatever I have sent to it and it will vanish (crash). I can attempt to send anything to it and the same problem occurs (audio or video; mp3, flac, avi, &c). I can test the same problem with VLC and the same results occur (vanish/crash).
If I close Opera (and optionally restart it), I again can use Totem and VLC. I have tried merely killing Opera's plugin wrapper (thinking it was perhaps related to a plugin seizing PA), but this does nothing for the matter. (Of course killing Opera does as this is more or less the same as closing Opera.)
I need to install some packages, but it fails because I previously installed gnome-shell testing, and now have the ricotz ppa packages conflicting with the default packages. See error below.
Code:
libgtk2.0-dev:
Depends: libgtk2.0-0 (=2.20.1-0ubuntu2) but 2.20.1-0ubuntu3~10.04~ricotz2 is to be installed
Depends: libpango1.0-dev but it is not going to be installed
Depends: libatk1.0-dev but it is not going to be installed
How do I remove these packages and re-install the default ones, without risking damage to my system?
UPDATE: I have now tried to remove this packages using ppa-purge and the new ubuntu tweaks, but for the life of me I cannot get rid of them.
What happen if we assign a static IP address to both linux and windows host?Consider host A is a ubuntu machine and host B is a windows machine. I first set a static IP for host A (W.X.Y.Z) and connect to it through ssh. Then I duplicate that IP for host B (W.X.Y.Z).The result was that I could no longer connect to the ubuntu machine!

Trying to install from a 10.04.1 Lucid LiveCD. The computer is pretty old but has Windows XP installed on it currently, which runs. (So it can't be that old!) I boot up and press F6 and I get the screen. When i try to install I get the Ubuntu logo with the 5 white/red dots and there is movement. The activity light on the CD drive flashes regularly and chugs along. At a certain point the screen attempts to change resolution or something and it goes all cyan and messed up. I assume that this is at the point where it attempts to load the graphical disk partition utility or whatever. Is there a way to pass a command line option at the install menu to make it a text only install or at a lower resolution? I'm not sure if it's trying to jump to the default IDID (or whatever it's called) resolution of the LCD monitor, since the video card may not support that resolution or something. (Because the video card is much older than the monitor).
