I am using valgrind tool callgrind to tracing MPI-IO calls. It trace the IO calls. Is there any way to trace this call till the underline file system specific calls? |

Hello sir, We are designing the ADIO for new PFS of our organization, for that we need to study the all hierarchy , we have seen the graph of call by a.out using valgrind tool but it was by elf . we want to see it while running program what we can see in gdb for c programe. All Function call, how and what parameter it pass from MPI-io calls to ADIO etc. How can I see it? |
