Re: Question Multithreading for NeutronHP (Alex Kav)

Dear Alex, Actually if you use 10.1.p01 neutron HP has been migrated to fully support HP, so the limitation mentioned in the twiki is not valid (I will fix the twiki, sorry for the confusion).

I think if you want to take full advantage of your multi-core laptop you should be able to run a MT job. The approach of using clones of your job with different random seeds will also work, but in that case you will have to handle merging of results and handling of jobs by yourself, while MT will do everything for you. Finally a different possibility is to use MPI (check examples/extended/parallel/MPI) but you will need to install MPI on your laptop.

In conclusion, I think that probably trying out MT is the simplest solution. In case you use too much memory you can reduce the number of threads (note that if you have this memory limitation you would have problems event with a multi-process or MPI approach).

Let me know if you need more info.

Regards, Andrea
