Abstract
A method for enhanced restart of a core dumping application is provided. The method includes stopping a plurality of threads in an address space, except for the thread performing the core dump. Computational segments are remapped to client segments. Each open file descriptor in the address space is closed. The application is terminated and the client segments are flushed to external storage.
Claims1
A method for enhanced restart of a core dumping application comprising:
- stopping a plurality of threads in an address space;
- continuing a thread, wherein the continued thread performs a core dump;
- remapping a computational segment to a client segment, wherein the remapping comprises:
- obtaining the client segment, wherein the client segment includes a plurality of client pages, and wherein the client pages comprise cached file data;
- copying a plurality of segment descriptors associated with a plurality of computational pages from the computational segment to the client segment;
- decrementing a first count, wherein the first count corresponds to a number of computational pages identified by the plurality of segment descriptors copied from the computational segment;
- and
- incrementing a second count, wherein the second count corresponds to the number of computational pages identified by the plurality of segment descriptors copied to the client segment;
- closing each open file descriptor in the address space;
- terminating the core dumping application;
- and
- flushing the client segment to an external storage.
