I'm using the IOdictionary kjmaHistory to store the local List t0 on disk from multiple processors.

IOdictionary kjmaHistory
    (
        IOobject
        (
            "kjmaHistory",
            runTime.timeName(),
            mesh,
            IOobject::MUST_READ,
            //IOobject::READ_IF_PRESENT,
            IOobject::AUTO_WRITE
        )
    );
List<bool> t0;
 
if (WRITE)
{
t0.setSize(T.size(),false);//inital value of list
kjmaHistory.add("t0",t0,true);//add list to dictionary
...
runTime.write();// store to disk
}
else//READ
 {t0 =kjmaHistory.lookupOrDefault("t0" ,t0);}

Every thing is ok with WRITE. Every processor saves dictionary in procNo/timeName directory. But when I try to READ written lists the problem comes. Every processor reads the list from timeName directory of master processor. (proc0/0.1)

Could you please tell me what am I doing wrong? How can i read data from processors directory but not from masters one?

I do not know why the perious code doesn't work, but now I managed to write one that works. If anyone can explain, please do not hesitate to tell.

IOdictionary kjmaHistory
    (
        IOobject
        (
            "kjmaHistory",
            runTime.timeName(),
            mesh,
            //IOobject::MUST_READ,
            IOobject::READ_IF_PRESENT,
            IOobject::AUTO_WRITE
        )
    );
List<bool> t0;
 
if (WRITE)
{
    t0.setSize(T.size(),false);//inital value of list
    kjmaHistory.add("t0",t0,true);//add list to dictionary
    ...
    runTime.write();// store to disk
}
else//READ
{
    dictionary kjmaHistoryDict(kjmaHistory.readStream(kjmaHistory.filePath()));
    t0 =kjmaHistoryDict.lookupOrDefault("t0" ,t0);
}

Every processor reads from its own directory at READ now, but that is not the case in previous code! Why don't they read kjmaHistory at IOdictionary declaration? Only the master node does and sends to others.
