在 Cray XC30 上运行 VASP 5.3.5 时,我看到以下错误:
Rank 4 [Mon Jun 1 14:58:35 2015] [c1-0c0s2n0] Fatal error in PMPI_Allgatherv: Invalid buffer pointer, error stack:
PMPI_Allgatherv(1235): MPI_Allgatherv(sbuf=0x49ead730, scount=1536, MPI_DOUBLE_COMPLEX, rbuf=0x49e95730, rcounts=0x494cdba0, displs=0x494d7360,
MPI_DOUBLE_COMPLEX, comm=0x84000007) failed
PMPI_Allgatherv(1183): Buffers must not be aliased. Consider using MPI_IN_PLACE or setting MPICH_NO_BUFFER_ALIAS_CHECK
6个月前编译的可执行文件不存在。有什么想法吗?
我将 GCC 4.9.2 与 Cray MPICH2 7.1.1、Cray LibSci 13.0.1 和 FFTW 3.3.4.1 一起使用。
