Question Multithreading for NeutronHP 

Forum: Multithreading

From: Alex Kav <Alex Kav>

Dear Geant4 experts! Our research work is measurements of soil carbon using neutron-gamma analysis (14 MeV neutron source and NaI(Tl) detector). I simulate our measurements using Geant4.10.01.p01. I use QGSP_BERT_HP, QGSP_BIC_HP physics and JNDL-4 and G4NDL4.5 neutron data libraries. At least 10^8 events are required to receive the suitable accuracy. It takes about 10 hours on the conventional laptop in sequential mode. To decrease the simulation time I supposed to use a multithread mode of simulation on cluster computer. Now I found that multithread mode have some limitation regarding Neutron HP – “Neutron-HP works only with small number of threads. We suggest to use this physics option in the sequential mode” ( What is your opinion regarding of my problem migration in multithread mode? Will I have the simulation time reduction from this migration? If possible, could you give some recommendation for simulation time reduction in my case? Thanks in advance, Alex
