c++ - Parallelizing loops containing function call -

-

Is this function equally suitable for call loops, or is it a more convenient circulation of loop which is the original Operation

For example, does it keep the equation instructions as below? 

  main () {.. #omp for paralel .. (i = 0; i & lt; 100; i ++) {a [i] = foo (and datatype,. ..); ...} ..} int foo (datatype * A, ...) {// complex operating is doing here // call other functions etc.}}

Thanks, Will Richard and Fakler, these comments were helpful and I had suggested the book RCHHD that there would be a deeper look. But before the end of the day, I want to make the current C code (actually a big loop that resides on top of the program), if possible, be parallel with OpenMP.

At this point, I need to help to make at least some parts of the loop parallel to some things, rather than to completely subdue the piral material, to simplify things, I How can I create a part 

 for  (i) n () (work1 () - (serial) work2 () - (serial) work3 () - (PARALLEL) work 4 () - (Serial)} // Does this work (3 to 0) work for private (PTR) except for # 3, except AMP P parallel Gone is to be added. Single {work1 () - (serial) work2 () - (serial)} work3 (ptr) - (baral) #omp single {work4 () - (serial)}}

Three bit notifications must be known:

  1. Keeps in mind, are you executing Fu?
  2. Does Fu () affect the shared portion, and is such a locking?
  3. Open without any How long does the loop take to run an MF?

Near work that takes long - many seconds or more - and it can be divided into independent parts (sometimes by refactoring, for example, by dividing the jobs and

the profile!

Incidentally, the results of each job)

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
