For some reason I found that my numerical integration runs much faster on Mathematica 9 than on Mathematica 10.
Since I sent my calculation to a cluster with 24 cores with the following command
Needs["SubKernels`RemoteKernels`"]; LaunchKernels[RemoteMachine["machine_name", 24]];
and the calculation is running in Mathematica 10. Therefore, I would like to know if there is any way to tell the machine that I want to use Mathematica 9 instead of 10?
The script is running with command like math-9 -script.
