为什么不用pardiso呢? |
这是IVF的BUG吧 |
程序还是不能终止啊~这是内存crash么? |
fcode 发表于 2014-4-7 21:50 谢谢管理员啊~确实可以有结果输出啦~ 可是程序为啥终止不了啊~ |
这确实是一个很诡异的情况。 IVF 的错误列表上这样说: severe (8): Internal consistency check failure 我想这个错误应该是 IVF 内部的缺陷导致的。而不是任何语法错误或调用方式错误。 通过更底层的一些逆向分析,得到一个比较奇特的“不正式”的解决方法: (其中 !// ****** 是我修改后的行,不要问为什么,我也不知道,呵呵) [Fortran] 纯文本查看 复制代码 PROGRAM Test INCLUDE 'mkl_dss.f77' INTEGER tIU(:), tJU(:), Idum(1), ITER DOUBLE PRECISION tUM(:), tXDIFF(:), tX(:) ALLOCATABLE tIU, tJU, tUM, tXDIFF, tX INTEGER nNonZeros,nRow INTEGER*8 handle INTEGER error OPEN (UNIT=10, FILE='testInfo.dat') READ (10,7004) nNonZeros, nRow CLOSE(10) ALLOCATE(tIU(nRow+1)) ALLOCATE(tXDIFF(nRow)) ALLOCATE(tX(nRow)) ALLOCATE(tJU(nNonZeros)) ALLOCATE(tUM(nNonZeros)) OPEN (UNIT=10, FILE='columns.dat') READ (10,7002) (tJU(II),II=1,nNonZeros) CLOSE(10) OPEN (UNIT=10, FILE='rowIndex.dat') READ (10,7002) (tIU(II),II=1,nRow+1) CLOSE(10) OPEN (UNIT=10, FILE='values.dat') READ (10,7001) (tUM(II),II=1,nNonZeros) CLOSE(10) OPEN (UNIT=10, FILE='loadVector.dat') READ (10,7001) (tXDIFF(II),II=1,nRow) CLOSE(10) ITER=1 C--------------------------------------------------------------------------- C Initialize the solver C--------------------------------------------------------------------------- error = dss_create(handle, MKL_DSS_DEFAULTS+MKL_DSS_OOC_VARIABLE) IF (error .NE.
