Boost.MultiIndex: Are there way to share object between two processes?
- by Arman
Hello,
I have a Boost.MultiIndex big array about 10Gb. In order to reduce the reading I thought there should be a way to keep the data in the memory and another client programs will be able to read and analyse it.
What is the proper way to organize it?
The array looks like:
struct particleID
{
int ID;// real ID for particle from Gadget2 file "ID" block
unsigned int IDf;// postition in the file
particleID(int id,const unsigned int idf):ID(id),IDf(idf){}
bool operator<(const particleID& p)const { return ID<p.ID;}
unsigned int getByGID()const {return (ID&0x0FFF);};
};
struct ID{};
struct IDf{};
struct IDg{};
typedef multi_index_container<
particleID,
indexed_by<
ordered_unique<
tag<IDf>, BOOST_MULTI_INDEX_MEMBER(particleID,unsigned int,IDf)>,
ordered_non_unique<
tag<ID>,BOOST_MULTI_INDEX_MEMBER(particleID,int,ID)>,
ordered_non_unique<
tag<IDg>,BOOST_MULTI_INDEX_CONST_MEM_FUN(particleID,unsigned int,getByGID)>
>
> particlesID_set;
Any ideas are welcome.
kind regards Arman.
