[Insight-users] Question on parallel computing of ITK

[Fucang Jia]

Hi, everyone,

I have access to a cluster of IBM RS/6000, each computer has four CPUs. The 
cluster is running AIX 4.3.3.0. ITK was compiled successfully using gcc 
3.2.1 without applications or examples, because there is no OpenGL installed 
in the cluster now.

Now I want to make use of parallel computing on it, but I do not know 
parallel computing, I only heard of the name of MPI and PVM. ITK implements 
Filter Level Multithreading and Application Level Multithreading, but I do 
not how to use them.

Firstly, Can ITK make use of multi-processor automatically? in other words, 
if ITK know the number of CPU, could it make several threads submitting to 
every CPU? I am afraid the key is no. So could you offer an example to 
illustrate it?

Secondly, which algorithm can be threaded, can MultiResolution 
MutualInformation, Watershed, Levelset algorithm which need extensive 
computing resource be parallel executed?

Thirdly, if there a need to study MPI or PVM programming to utilize parallel 
computation for ITK now?


Thanks a lot!

Fucang
