发帖数: 13748 | 8 剛弄上的Verizon DSL，他家給配的是Westell 6100F，型號為F90-610015-06的Modem。
默認是路由加Bridge的PPPoE模式，按照網上的指導改成了Bridge模式，試圖連接CP

Modem的Bridge設置應該正確了，因為在Windows里建立了PPPoE鏈接，可以輸入用戶名
密碼然后撥號連上網絡。但是接上無線Router以后，Router雖然顯示的是Connected，
但是完全上不了網。
會是什么問題呢？難道Verizon禁止路由？還是什么其它問題？我該怎么測試？前提是
最好不要再找一個Modem或Router。。。

发帖数: 734 | 12 The :: is just the new syntax for declarations in Fortran 90/95/2003.
In F77 you would write
INTEGER X
DIMENSION X(1:N)
or more compactly
INTGETER X(1:N)
and in F90+ you would write
integer,dimension(1:n)::x
The :: separates the type and properties from the list of variables.
It does not have the same meaning as :: in C++.
You can probably even omit the :: (at least in some cases you can).
I have gotten into the habit of always writing the :: where possible. |

我用F90。偶尔会遇到类似的BUG。
如果没有WRITE语句，程序正常运行，不报错，但是结果是错的。
中间添加一个WRITE语句，程序就报错（或者结果就突然对了）

try{
Object A("aaa");
A.do();

}catch(exception& e){
cerr<<"not handling"<

现象：如果 A.do() 发生异常，这个 exception 并没有被 catch 捕捉到并处理。但是

发帖数: 339 | 36 What I said was correct (see your F90 manual description about "contains").
But it is also true that if you use implicit none in the subroutine,
it will prevent the internal subroutines to reference other internal
subroutine.
Nevertheless, even in that case they can still access the variables in the
main program.
Instead of the example you give, try the following:

contains

发帖数: 186 | 40 If you're using Fortran 77, the restriction is still there.
Even though your compiler allows you using more than 6 characters,
it's just the extension of your compiler, rather than the standard of F77.
If you're using Fortran 90, there is no restriction on the length
of the variable names. This is the standard that any F90 compiler
should comply with. |

They are practically not "real" compilers.
They need to call some background Fortran compilers to

So, when installing the MPI, if the mpif77 is linked to

even mpif77 can compiler Fortran 90 programs in which
the MPI subroutines are called. |

发帖数: 2334 | 45 I asked the same problem on a Fortran newsgroup. Somebody suspected it might
be caused by a compiler bug. I don't know what that means.
That guy also thinks I used F90 compiler. He said the automatic array is
illegal in F77.
Then another guy suggests me to do as follows:
program main
real*8 a(0:10)
call sub(a)
end
subroutine sub(b)
real*8 b(*)
b(0) = 7
end
It is just like those subroutines in Lapack. But there are lots of
work arrays in my code, I don't know how realistic this way is. |
|
l**g
发帖数: 5 | 46 1。这里应该有错：
real*8 b(*) == real*8 b(1:)
所以这里 b(0) 是 bound violation，a(0)的值并不会改变。
2。我觉得你的程序是不是不自觉地引用指针，引起内存访问出错。比如
subroutine sub(b1,N)
real*8 b1(0:N)
b(0) = 7
end
subroutine sub(N)
real*8 b2(0:N)
b(0) = 7
end
其中b1是双精度数组；但fortran把b2解释为local指针数组，指向double.
前者是对的，后者就会出错。
命令g77/f77执行的可能是f90 或 f95
