Vector Space ModelThe basic idea is to represent each document as a vector of certain weighted word frequencies. In order to do so, the following parsing and extraction steps are needed.Ignoring case, extract all unique words from the entire set of
Using ddd/gdb: Use of a debugging tool like gdb can save you large amounts of time and frustration in any debugging project. But it is especially useful in debugging parallel programs. Whenever possible, avoid doing your debugging by simply adding

Thus far we have used the debugger to start the program we want to debug. But with MPI programs, we have used mpirun or mpiexec to start programs, which would seem to present a problem.[3] Fortunately, there is a second way to start gdb or ddd that

I have a struct struct S{string Str;int Score;}to store personal info. In VC++ 6.0, I can use CFile::Write() to those struct instances, corresponding to individual personal info, into hard disk file.However, in a pure C++ framework, how to do
並行計算程式設計時,常面臨把 一系列任務分配給 n個節點的問題。比如,在經典的計算pi值的程式中 for (i = myid + 1; i <= n; i += numprocs) { x = h * ((double)i - 0.5); sum += f(x); }myid出現在迴圈設計中,它的出現使得,各個進程(節點)對迴圈作不同的解釋,比如 numprocs=3, n =15(1)node-1/proc-1對迴圈的解釋是for(i=1; i<15;
