[CHiPPS] How To Record Information of Alps Processed nodes on A parallel Cluster?

[Yan Xu]

In AlpsKnowledgeBroker.h, there are members like

    /** The number of nodes that have been processed. */
    int nodeProcessedNum_;

    /** The number of nodes that have been branched. */
    int nodeBranchedNum_;

    /** The number of nodes that have been discarded before processing. */
    int nodeDiscardedNum_;

    /** The number of nodes that are pregnant. */
    int nodePartialNum_;

    /** To record how many nodes processed by the system
        (used in parallel code). */
int systemNodeProcessed_;

Probably, you can also take a look at AlpsKnowledgeBrokerMPI.cpp and find out how the  systemNodeProcessed_ gets computed.

Subject: [CHiPPS] How To Record Information of Alps Processed nodes on A parallel Cluster?

Dear professors,
     I am know working on record the information of processed nodes in parallel ALPS.
     I print the information of every node in AlpsSubTree.cpp, exploreunitwork() and ramup() where there is "++numNodesProcessed" to the stdout.
     But finally, the number of nodes printed(the cluster will collect the stdout of all machines and write to one file ) is much less than that in the log file where search result is summarized.
     While in a serial system, the two number are the same.
     I don't know where is wrong. Could you help me?

     Best Wishes!
