Example text

In the beginning of previous work, we introduced new implementations of the memchecker framework within Open MPI to check for memory problems in parallel applications [3, 11]. It extends and integrates the Valgrind [10] Memcheck tool in memchecker to observe communication buffers during the communication as well as user specified parameters. We also introduced a newly developed memory checking tool, MemPin, which has similar functionalities as Memcheck and its extension. This new tool provide more flexibilities to be integrated in the MPI libraries.

Problems, bugs and critical issues in these applications, which have been found using the debugging tool, will be mainly focused on. The structure of this paper is as follows: Sect. 2 shows the basic idea and functionalities of Intel PIN; Sect. 3 first introduces the functionalities and architecture of MemPin, then it gives a detailed description on the integration the tool in Open MPI libraries; Sect. 4 shows details of the pre- and post-communication checks for parallel applications; then in Sect.

The Memory Management component is in charge of inserting, deleting or updating memory entries. An memory entry contains information of a communication buffer, including starting address, size, callback function pointer and memory operation flag. All memory entries are stored in the Memory Registration Storage, which is a multiple map data structure. The Search Engine intercepts the translated application code from Intel Pin, and find the match access according to the storage. If a match is found, it will send corresponding memory information to the Callback Engine, which then will directly call the callback function registered with the memory entry.
