I am trying to extend my parallel computation abilities by adding some remote kernels to my current laptop kernels (just 2 cores).
First of all let me ask what are you experience with doing this, is the thing really giving a boost to your computation?
I have some little experience with my two local cores and sometimes it actually reduced the computation time of a factor two, using
ParallelTable, but at other times, it was ten times slower!
I have found out how to connect to the remote machine and start a kernel via command line with one simple ssh command of the type
ssh user@host mathematicacommand
This also works with the SSH implementation by Wolfram
java -jar /Applications/Mathematica.app/SystemFiles/Java/WolframSSH.jar user@host mathematicacommand
Now I have tried to use the remote kernel configuration on Mathematica, but the standard config seems not to work, so I wanted to do something that works by giving command on the Mathematica frontend to launch these remote kernel.
I have seen some examples for this, such as this, but they are not terribly applicable to my case.So, let me ask you guys for a series of commands I can issue on the Mathematica frontend to launch remote kernels by hand.
