Patch 3.7.6 to OpenMX Ver. 3.7 Date: 2013/09/01 14:47 Name: T. Ozaki Dear all, A patch 3.7.6 to OpenMX Ver. 3.7 is released at http://www.openmx-square.org/download.html The purpose of the patch and how to apply it can be found below. Thank you very much for your cooperation in advance. Best regards, Taisuke Ozaki ------------------------------------------------------ Content of README.txt ***** How to apply the patch3.7.6: ***** cp ./patch3.7.6.tar.gz openmx3.7/source cd openmx3.7/source tar zxvf patch3.7.6.tar.gz make install ***** patch3.7.6.tar.gz ***** contains neb.c Band_DFT_kpath.c Band_DFT_MO.c Force.c Set_Orbitals_Grid.c RestartFileDFT.c EigenBand_lapack.c Set_Allocate_Atom2CPU.c ***** purpose of patch3.7.6.tar.gz ***** Related to neb.c: In case that the OpenMP parallelism is disabled by adding -Dnoomp as compiler option for CC and FC in makefile, the patch should be applied. Related to Band_DFT_kpath.c, Band_DFT_MO.c, Force.c, and Set_Orbitals_Grid.c Variables were not properly assigned for the parallelization using OpenMP in those routines, which may cause serious problems. The problem will be resovled by applying the patch. Also, there was a serious bug in Band_DFT_MO.c, which causes an incorrect output of LCAO coefficients in *.out. The problem will be resovled by applying the patch. Related to RestartFileDFT.c: It seems that a deadlock sometimes happens in the MPI calculation when BullxMPI is used as MPI library. The problem is resolved by applying the patch. Related to EigenBand_lapack.c: In some cases, it is possible that erratic noise appears in the band dispersion. The problem is resolved by applying the patch. Related to Set_Allocate_Atom2CPU.c: In the MPI parallelization, two or more MPI processes are used for a system including a single atom, the calculation may stop due to segmentation fault. The problem is resolved by applying the patch.
