高手,请教个问题:pwscf在优化纳米粒子的几何方面性能如何了?是不是巨慢务必了,我们只有12个CPU的,至强服务器。
我想优化一个(TiO2)38的几何。

俺不是高手~俺用的是普通的电脑,没试过那么大的体系。
虽然各个软件间有效率差异,但是所有基于赝势平面波的DFT软件对资源占用和速度上差距并不是数量级级别的。
如果体系非常大,而电脑又比较不给力,建议考虑Siesta,甚至紧束缚~
思想重于技巧,内涵重于表象

B.  Most noticeable achievements

B.1 Spinor parallelization is available,
    and can be combined with the k-point/planewave/band parallelisation.
    Algorithm LOBPCG must be used (wfoptalg=4 or 14 / paral_kbg=1)
    The wavefunctions are fully distributed, over spinor components + k-points + planewaves + bands.
    It is OK in both norm-conserving and PAW cases.
    New input variable : npspinor.
    Work by M. Delaveau helped by M. Torrent

B.2 Parallelism over images is available, and can be combined with the k-point/planewave/band/spins/spinor parallelisation.
    This is relevant for the string method or path-integral molecular dynamics (see the input variable imgmov/=0).
    Tests have shown linear speed-up for test cases (10 images) up to 5000 processors.
    It is OK in both norm-conserving and PAW cases.
    New input variable : npimage. Moreover, its value can also be deduced by ABINIT.
    New test case : in tests/paral test #AC
    Work by G. Geneste and M. Torrent.

B.3 Contour deformation GW calculations have been vastly improved, e.g. through
    the availability of input variables to control the frequency grid spacing
    (cd_use_tangrid, cd_halfway_freq, cd_max_freq, cd_subset_freq).
    There have also been big improvements in the abilities of the utility
    mrgscr : now it is not only possible to split up a screening calculation
    by q-points and later merge them, but also to split up the calculation
    for subsets of frequencies per q-point for later merge with mrgscr.
    There are speed-related improvements, and specific information crucial for effective
    calculation is now printed, particularly regarding how far along the real
    frequency axis information from the screening is needed in the self-energy calculation.
    (This as well as other useful info is turned on by setting prtvol=10.)
    New input variables: cd_use_tangrid, cd_halfway_freq, cd_max_freq, cd_subset_freq
                         cd_full_grid, cd_custom_imfrqs, cd_imfrqs
    Work by M. Stankovski, G. Antonius, M. Giantomassi, D. Waroquiers.

abinit更新太勤,可惜没有更好地支持GPU。结构优化真是折腾时间。

提供新版本不如提供新的好的赝势来得实在哦~
