Video streaming in Kubuntu 8.10

I have tried several player such as Kaffeine, and mplayer, but finally I ended up in Totem for my Kubuntu 8.10 intrepid. I need to install the additional plugins and extra plugins.
I can run the video streaming from one of the website that I usually watched.

Segmentation fault error when running in Hilbert

When I tried to run my code in Hilbert cluster with 4 nodes and 4 cpus each node, I kept on getting this error

Guide to available mathematical libraries

I just found an interesting site to help you find the required mathematical libraries for computation.

checking number of free processors and jobs

to check the number of free processors:
mdiag -n
To check the status of the job, either you can use
qstat -a
or
checkjob -v PID
where PID is your job ID, you can use qstat -a to check your job PID. checkjob tells you the architecture and which processors the job is running.

Installing IT++ in Hilbert and Darwin

Compared to installing in Turing (SGI Altix), I need to install the FFTW library and not specify F77 flag when installing IT++ in Hilbert.
./configure –prefix=$HOME/local CPPFLAGS=”-I$HOME/Download/boost_1_36_0 -I$HOME/local/include” LDFLAGS=”-L$HOME/local/lib”
While when installing in Darwin
./configure –prefix=$HOME/local CPPFLAGS=”-I$HOME/Download/boost_1_36_0 -I$HOME/local/include” LDFLAGS=-L$HOME/local/lib F77=ifort

Installing IT++ in SGI Altix

I am installing IT++ in my compute servers SGI Altix (Turing). I want to use the Intel compiler MKL for building IT++ libraries. To do that:

export LDFLAGS=”-L/opt/intel/lib/64″
export CPPFLAGS=”-I/opt/intel/include -I/scratch/ihpcoka/Download/boost_1_36_0″

I used Boost libraries in my IT++ modification. And then do a configure
./configure –prefix=/scratch/ihpcoka/local CXX=icpc

Then type make, make check, and make install. During make check, I got [...]

Send/receive C++ vector using MPI

I am using IT++ for some of my code and I tried to parallelize it. It came to the point where I need to sum up all the vectors from all the process. So in MPI, I will need to use MPI_Reduce. My question is since IT++ vector is not an array, can we then [...]
