Hello everyone,
I've been trying to create a simple way to serialize C++ objects so I
can send messages among different processors (using MPI). Something
very simple is shown below:
template <class StorageType>
void Send(StorageTyp e& c, int dest, int tag, MPI_Comm comm) {
typedef typename StorageType::Va lueType ValueType;
int size = c.size()*sizeof (ValueType);
char* buffer[size];
memcpy(buffer, &c[0], size);
MPI_Send(&buffe r, size, MPI_BYTE, dest, tag, comm);
}
I tested the templated function with arrays of integers and it works
fine. However, when I try to use the dynamic_bitset provided by the
boost library, I cannot pass a reference to c[0] because operator& is
private for that class. Is there another efficient way to do a bitwise
copy???
Thank you all,
a²

The boost mpi library does this already. While not in the 1.34.1 released version it's available from their svn/cvs site.
I could use the boost library in my machine. However, I doubt that the
cluster I will run the parallel program on will have the latest
version of the boost library.
Don't you compile/link on your machine and transmit exe's to the cluster?
I'm not sure why they would need boost installed?

Let me describe the flow of my program first.
1. Deserialize data from xml file.
2. Addition of "PersonType" class to the AllPersonalData.
3. Serialize data back to the xml file.
My question is I have to use an array PersonType in the AllPersonalData class. But if I have to implement the "Addition of
PersonalType" (i.e. the step 2), I have to use ArrayList instead of a fixed length array. I know that I can use the ArrayList as an...

I'm pretty comfortable with simple XML serialization of objects. However I
observed something the other day and I wanted to know if I solved it the
right way.
Basically if I have a string which contains a single xml node, I can
serialize with this line of code:
object = (object)serializer.Deserialize(new

Hi
I am serializing a dataset using a binary formatter as follows:
IFormatter formater = new BinaryFormatter();
formatter.Serialize(stream, ds); // ds=DataSet, stream=MemoryStream
....
DataSet ds2 = (DataSet)formatter2.Deserialize(stream2);
For the size of my DataSet, its taking 0.8 seconds to serialize and 2.3
seconds to deserialize.

Hello,
I have been developing an Ajax-style framework for couple of years now.
Now I am reworking some parts of it. The problem was that I used to use
JSON for JavaScript value serialization/deserialization, but this
approach has some limitations when it comes to large data - the
JavaScript at the client side has too much load working with it. So, I
thought, I'd rework the serialization to XML format.
The idea is short-as-possible...

I have integrated APIs from a third party into my framework. The third
party is essentially a .Net wrapper on top of an existing set of C++
classes and structs.
I want to pass-around objects in these native structures as much as
possible - that is I don't want to fool around with object
serialization/deserialization. Data rates approach several hundred
thousand objects per second, hence I simply can't pay the performance
penalty this...

I'm looking for an example that would show how to serialize a c++
object at it's simplest w/o using any other api's. I have a class that
I want to serialize and then pass to my obj-c class so I can send it

I'm just looking for how to serialize it, then pack it back up on the

Any help much appreciated.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
