Reasons of switch from Ubuntu Linux to Debian and back to OpenMPI for CUDA GPU potential

Hi there
I have made some major changes to stuff. I have switched back to OpenMPI as the FastFlow design patterns appears not to allow easy integration with R scripting calls with RInside. I went with the working examples from RInside which uses OpenMPI. As I set up the cluster, Ubuntu was not playing nice so I tried Debian which worked. As a result, I have included some useful links for those following me on how this HFT is being built.
Get the benefits here.
Got questions or comments, let me know.
Thanks Bryan

How to build Beowulf cluster aks HPC for Open MPI C++ apps like HFT with R with RCPP RInside package on Debian Linux #rstats #linux

How to build Beowulf cluster aks HPC for Open MPI C++ apps like HFT with R with RCPP RInside  package on Debian Linux #rstats #linux

Install Debian Etch from: and follow first CD install instructions:

http://www.debian.org/CD/http-ftp/

Install Debian Virtual Machines in Virtual Box as usual

http://www.wired.com/geekdad/2012/02/debian-linux-on-oracle-virtualbox/

Go with all default options.  You can always clone  a second  client VM to create a slave.

Set up hostname and configure network via: (choose the static address  not DHCP)

http://www.debian-administration.org/articles/254

Note that you could loose network connectivity soo add an additional Network Adapter with Bridged Adapter for each VM. within the Virtual Box setting. so see next step

Ensure each VM has network adapter setting to Virtual Box Host Only

http://christophermaier.name/blog/2010/09/01/host-only-networking-with-virtualbox

Create NFS for both virtual machines as server and client:

http://www.howtoforge.com/nfs-server-and-client-debian-etch

Note: When  editing exports on the server with:

/home           192.168.0.101(rw,sync,no_root_squash)

/var/nfs        192.168.0.101(rw,sync)

 

Note that 101 is the client!. ALso, I have when I try to auto mount during boot on the client, it would hang. I just created a shell script to do the mounts manually when you boot.  I just called this /etc/mountmaster.sh

 

If you need to add users do:

http://www.debian-administration.org/articles/2

You should be able to proceed with the following set up of your Beowulf cluster:

http://www.debian-administration.org/articles/2

To understand nad configure ssh connections with no passowrd, use:

SSH your Debian servers without password

This could be useful http://wiki.debian.org/SSH but note it uses RSA not DSA

If confused, use this next one but remember the ssh server is the Open MPI slave while client is the Open MPI since it logins into the Open MPI slave.

I may need to abandon Ubuntu Linux due to weird bugs over to CentOS or Debian #linux #ubuntu

I may need to abandon Ubuntu Linux due to weird bugs over to CentOS or Debian #linux #ubuntu

This is frustrating to get an NFS environment wiith Ubuntu 11.04. It appears there could be strange bugs in Ubuntu preventing from working. Nevertheless, I am moving everything something else to Debian or CentOS. I will report when I see this Beowulf cluster working.

Don’t ask about these bugs? It seems there is sloppiness going on the in Ubuntu camp as I don’t like wasting days to get something to work!

Update I was able to set a NFS client and server on my new Debian environment. Funny how stupid Ubuntu is getting. I will do a posting on this once completed!

Finally, a Linux flavour that works in desktop form. It is called CentOS 6. Thank you! Forget Ubuntu and Debian

Forgot those latest versions of Debian and Ubuntu. They seem not to work unless you love the command line. I like CentOS anyways as it is 100% compatible with Red hat Enterprise Linux.

Is there a real comparison between Ubuntu and Debian? They seem to get closer

Is there a real comparison between Ubuntu and Debian? They seem to get closer
First, Ubuntu is a derivative of Debian which some will claim as the purest Linux version out there. I tend to agree as it can be very light weight as compare to the prettier and feature rich Ubuntu. I feel Ubuntu is more like for those who are looking for a distinctive interface that they will not get from Windows 7 or Mac OS X. It seems to me that there is a version specially designed for net books. Kind of cool. I really like Ubuntu.
Then I forgot about good old Debian which is one of those more mature Linux distribution. I would also claim it is one of the oldest too. Ubuntu is a nice fork of Debian I believe. Some may think I am wrong but Debian for sure is a closer version of Linux as compared.

If you want to deploy a testing or development version of Linux or Unix, I would try out Debian. It never gives me any issues as compared to Ubuntu or Red Hat or even CentOS. Check it out you might be impressed but the light weightness of Debian.
