I am trying to follow this tutorial for building and running an MPI application on an ARM based Ubuntu 11.10 system.
When installing open-mpi environment on my PC machine, the sample program runs well. However, trying the same on the ARM machine, the terminal hangs up and I need to kill the MPI process from a second terminal in order to release it.
The MPI packages I installed using apt-get, on both machines, were mpi-default-dev and mpi-default-bin, so I assume that the packages are as updated as they can be.
The first sample program in the tutorial makes every process prints a "hello" message with some info. On the PC I get messages from all 8 processes (although running on a single core) and then the program ends. On the ARM, I get no output at all. The program is just stuck immediately after launch.
Any idea on what's wrong? I am not sure even where to start to debug this?
Update: I tried removing the OpenMPI package and install the alternative MPICH2 package - but the result is just the same.
Ubuntu 11.10 did not ship with a functional Open MPI implementation for ARM (although it may have shipped with a nonfunctional one). Ubuntu 12.04 did.
I would recommend building your own Open MPI from source - available at http://www.open-mpi.org/software/ompi/v1.6/, unless you can update to a more recent version of Ubuntu.
Alternatively, you could rebuild the 11.10 package using the fixes pointed out in https://bugs.launchpad.net/ubuntu/+source/openmpi/+bug/949044.

Using a virgin (but updated) version of Rocky Linux 8.5, I am trying to install VMware Workstation 16.2.1 (and others), but get compile errors during the first attempt to run, when vmmon and vmnet are being built.
All the proper, current headers from kernel-devel and kernel-headers are installed.
I tried upgrading to the 5.16.4 kernal at kernel.org, with all associated headers, and basically get the same errors.
"Unable to install all modules." i.e., vmmon and vmnet
Posts i have found with searching the net seem to indicate that there was a "back-port" of an upstream fix to Rocky that has affected the ability to build the loadable kernel modules necessary to run vmware - but i cannot confirm this is actually the problem that I am experiencing.
So i simply ask these questions: Can anyone (today) install VMware Workstation 16.2.1 (or any version), on a fresh install of Rocky Linux 8.5?
If so, would you please point me at your installation instructions, because I am unable to build "vmmon" and "vmnet" modules today (2022-01-04), that allow me to actually run virtual machines with vmware? (The kernel modules fail to compile and build.)
(and after 15 years of using stackoverflow i do not have the reputation to create a "rocky-linux" question tag...)
See https://unix.stackexchange.com/questions/689436/the-vmmon-and-vmnet-vmware-workstation-kernel-modules-fail-to-build-on-rocky-lin
mbubecek's instructions work for a variety of releases and should compile perfectly and run without issue, if you follow his instructions.
I have successfully used these methods at least a half dozen times with Rocky 8.5 and 8.6 with vmware workstation 16.1 up to version 16.2.1
NOTE: This error is NOT Rocky Linux specific. Also happens on some versions of RHEL 8 and CentOS 8.x I would also expect this "fix" to work on all of the other linux versions that are RHEL 8-derived.
I've been having difficulty with the same issue, and a colleague pointed me to check my kernel. This is our "official" resolution. See if the below works for you.
This is due to differences between the kernel and the source code for the VMWare modules, see here for more information. You can get the correct kernel modules, and build them by executing the following commands
wget https://github.com/mkubecek/vmware-host-modules/archive/workstation-16.1.0.tar.gz
tar -xf workstation-16.1.0.tar.gz
cd vmware-host-modules-workstation-16.1.0/
make
sudo make install
If you get the error,
crosspage.c:53:16: fatal error: linux/frame.h: No such file or directory
The error is described here. The solution is to remove (i.e. comment out) the offending include file in crosspage.c After doing the sudo make install, it is a very good idea to restart you host.
You may need to manually insert the modules into the kernel the first time after running make install'. The kernel modules (vmmon.ko and vmnet.ko) will be found at /lib/modules//misc. The following set of command will do this:
cd /lib/modules/$(uname -r)/misc
sudo insmod vmmon.ko
sudo insmod vmnet.ko
The modules should be load automatically after a restart/reboot.
If you update vmware to a different version (say 16.2.1) you may need to this again. Just change the versions in the above commands. If you hit the update button on the splash-screen and failed to notice the version you are updating to, you can run `vmware -v' at a command prompt to get the version you updated to.
Can a python 3 script be compiled in a linux environment in such a way as it can be run under Windows?
If so what compile tool? ie. py2exe or pyinstaller ect.
You're looking for cross-compilation, and the answer is no.
Can I package Windows binaries while running under Linux?
No, this is not supported. Please use Wine for this, PyInstaller runs fine in Wine. You may also want to have a look at this thread in the mailinglist. In version 1.4 we had build in some support for this, but it showed to work only half. It would require some Windows system on another partition and would only work for pure Python programs. As soon as you want a decent GUI (gtk, qt, wx), you would need to install Windows libraries anyhow. So it's much easier to just use Wine.
Can I package Windows binaries while running under OS X?
No, this is not supported. Please try Wine for this.
Can I package OS X binaries while running under Linux?
This is currently not possible at all. Sorry! If you want to help out, you are very welcome.
You may use Wine or the Windows Subsystem for Linux to attempt using PyInstaller to build stand-alone binaries for different operating systems, however, neither PyInstaller, nor Py2Exe, nor cx_freeze, nor any tool to my knowledge does this.
Effectively, in-order to do something like this, you would need a cross-compiler such as MinGW or VC++ for Linux, and integrate it into PyInstaller, which is very far outside of the scope of the project. It is much easier to use WINE or having a dual-boot system or multiple development computers.
Introduction
I've just installed a networking simulator Called Netkit. On Debian stretch stable. Using the official installation guide here.
Installation
After setting the correct paths and installing. I then run the check_configuration.sh script.
Everything is checked OK, and it has found the terminal emulator xterm which is needed for netkit. And recieve the complete message.
[ READY ] Congratulations! Your Netkit setup is now complete!
Enjoy Netkit!
The Problem
Running netkit using the command:
vstart pc1
The xterm netkit-kernel emulator starts running. However I'm getting an infinite loop of the same error message:
ubda: can't open "home/foo/netkit/pc1.disk" failed, errno= 13
So im guessing it's because the file is missing? if so how do i obtain it? and if not, what is causing this error. I've followed the install guide completely.
I'm assuming your system is not a 32bit system. Netkit is only supported on the 32-bit architecture(unless the compatibility libraries are installed). Hence I would suggest you download a 32-bit VM(instead of installing the libraries) and run Netkit on the same(worked fine for me).
Check position of your lab-folder..
I am running a virtual CentOS environment using virtual box. I am trying to install and run enthought canopy. But after installation canopy won't run. I simply get
./canopy: line3:/home/Andrew/Canopy/bin/_python: cannot execute binary file
./canopy: line3:/home/Andrew/Canopy/bin/_python: Success
But nothing happens. a GUI should open up.
I am wondering what is causing this error.
It is basically a fresh install of operating system. Only other thing I have done is installed python 2.7. Also I am a novice at using linux-style OS. so I may be missing something very basic
I am trying to install CUDA on a server running Ubuntu 10.04.
I followed the NVDIA instructions and installed the "CUDA toolkit for Ubuntu Linux 10.04", "GPU Conputing SDK code samples",and "Developer Drivers for Linux (260.19.26) (64 bit)", my system is 64 bit. This installation seems successful. everything downloaded from http://developer.nvidia.com/object/cuda_3_2_downloads.html#Linux
According to the messages of the installation packages, I added /usr/local/cuda/bin to PATH, /usr/local/cuda/lib64:/usr/local/cuda/lib to LD_LIBRARY_PATH
Then, I tried to run the sample programs. The strange things is, some of them can be run, and some of them don't even through they can be made with no problem.
For example,
- convolutionSeparable will just stop there without any message, I can kill it by ctrl + c.
matrixMul outputs a line
Device 0: "Quadro 5000" with Compute 2.0 capability
and stop there, again can be killed by Ctrl+C
clock works, outputs
PASSED
time = 12574
Press ENTER to exit...
simpleMultiCopy outputs PASSED
MonteCarlo outputs PASSED
simpleZeroCopy outputs PASSED
bandwidthTest stops there with blinking cursor for ever.
What is wrong with this?! How can I check if my CUDA installation is successful ? What is wrong with those programs don't run? They don't even have a error message.
I would start by upgrading the driver to 260.19.36, which can be found here. Then I would suggest running nvidia-smi -a to see if the driver is happy. Then I second the suggestion to run deviceQuery to see if the CUDA Toolkit 3.2 is working.
If deviceQuery output appears nominal, then I would start adding printf's to see where things go awry in matrixMul.
What does deviceQuery say? Also check the output of dmesg right after you run that program to see if you can figure out whats up.
Another tip, if you still are having issues, is try running:
strace ./deviceQuery 2> out.txt
Then check out.txt to see if you can find any clues why this error is occuring.
I have similar problem but solved by updating kernel and drivers.
