[Camino-users] Possibility of parallelization for the datasynth command.

[Rajalekshmi Deepu]

Hi,

We have a cluster with each compute node having 24 physical and 24 
logical cores. If I wanted to run the below command, say for 24 voxels 
instead of 1, can I distribute it to the 24 cores? Probably with 
-separateruns option. Will this generate different data as we use MC?

  datasynth -walkers 100000 -tmax 10000 -p 0.0 -voxels 1 -initial spike 
-voxelsizefrac 1 -diffusivity 0.6E-9 -schemefile myScheme.scheme1 
-substrate cylinder -packing square -cylinderrad 3E-6 -cylindersep 
6.1E-6 -outputfile regCyl_r=3E-6_spike.Bfloat

Also I am not clear with the option -seed. Here 
<http://camino.cs.ucl.ac.uk/index.php?n=Tutorials.MCSimulator> it says, 
"|-seed|specifies the seed for the random number generators to use."

On the other hand, here 
<http://web4.cs.ucl.ac.uk/research/medic/camino/pmwiki/pmwiki.php?n=Man.Datasynth> 
it says "Specifies the random seed to use for noise generation in 
simulation trials."

Bit confused now.

Any help will be appreciated.

Thanks and regards,

Lekshmi
