| 内容記述 | 3-field Landau fluid (LF3) model describes the ion tem- perature gradient driven drift wave (ITG) turbulence in Toka- mak plasmas[1]. It is applied to investigate the internal trans- port barrier formation which gives the improved energy con- finement time[2]. The code is developed using the spectral method[3] which is parallelized using Message Passing Inter- face (MPI)[4, 5]. Since the calculation cost of nonlinear mode coupling is most expensive part, so that various schemes for the decomposition of do loop are tested to optimize it. It is found that the best scheme gives roughly 30% faster than the standard decomposition method. |
