【求助】vasp4.6 并行編譯警告怎么處理 已有4人參與

我用mpif90和mpiifort編譯都有這樣的問題， ------------------------------------------vasp 4.6----mpif90 mpif90 -FR -lowercase -assume byterecl -O3 -c elpol.f90 elpol.f90(693): warning #7866: The statement following this DEC loop optimization directive must be an iterative do-stmt, a vector assignment, an OMP pdo-directive, or an OMP parallel-do-directive. !DIR$ IVDEP 好像和omp有關(guān)，哪位大俠能指教一下，omp 指的是什么？ 初學(xué)編譯不大了解這塊內(nèi)容。 上面的問題怎么解決呢？ 我的mpif90 的版本是： mpif90 for 1.0.2 Version 11.1 附上我的makefile : .SUFFIXES: .inc .f .f90 .F #----------------------------------------------------------------------- # Makefile for Intel Fortran compiler for P4 systems # # The makefile was tested only under Linux on Intel platforms # (Suse 5.3- Suse 9.0) # the followin compiler versions have been tested # 5.0, 6.0, 7.0 and 7.1 (some 8.0 versions seem to fail compiling the code) # presently we recommend version 7.1 or 7.0, since these # releases have been used to compile the present code versions # # it might be required to change some of library pathes, since # LINUX installation vary a lot # Hence check ***ALL**** options in this makefile very carefully #----------------------------------------------------------------------- # # BLAS must be installed on the machine # there are several options: # 1) very slow but works: # retrieve the lapackage from ftp.netlib.org # and compile the blas routines (BLAS/SRC directory) # please use g77 or f77 for the compilation.

這個警告信息問題不大。OMP指的就是openmp，支持多線程的并行。但是vasp里面好像是沒有實現(xiàn)支持openmp的部分。 這個信息可能是來自ifort的-O3優(yōu)化l，這個-O3會導(dǎo)致程序進(jìn)行最大程度的優(yōu)化，比如就遇到，將循環(huán)的loop進(jìn)行優(yōu)化。你可以將它降低到-O1試試。 |
