| gyhuang@ucdavis.edu: Mar 31 11:58AM -0700 Hi I met a similar issue. Finally I use thread specific key as follows: function(){ Sigjmp_buf localbuf; pthread_setspecific(pthread_key_t key, (const void *)&localbuf); if (sigsetjmp(localbuf, 0) != 0) { //assign error //return error } //done with everything pthread_setspecific(pthread_key_t key, NULL); } void signal_handler(int sig) { if (sig == SIGSEGV){ void * sigjmplocal =pthread_getspecific(pthread_key_t key); if (sigjmplocal) siglongjmp(*(Sigjmp_buf*)sigjmplocal, 1); } } From book, SIGSEGV is sent to the thread that triggers it. Is it safe to use this approach? It seems working with simple UT. But I can not foresee its risk. Thanks a lot. On Friday, July 20, 2012 at 2:42:22 PM UTC-7, Michael Podolsky wrote: |

This parallel algorithm employs one distributed i mean: it makes the insert() method of a decent throughput |
