Dear openmpi developers, I have been developing our hybrid(MPI+OpenMP) application using openmpi for five years.
This time, I tyied to install a new function, which is c++ based multi- threaded library and it heavily repeats new and delete objects in each thread. Our application is so called "MPI_THREAD_FUNNELED", and openmpi-1.6 is built using --with-tm --with-openib --disable-ipv6. My trouble is that it works very well with "--mca mpi_leave_pinned 0" but, when mpi_leave_pinned is enabled, it often causes segfault like below. I note that it works fine on Windows multi-threaded platform combined with mpich2. Furthermore, regarding multi-thread(none MPI) version, it also works fine enven on linux environment. #0 0x00002b36f1ab35fa in malloc_consolidate (av=0x2aaab0c00020) at ./malloc.c:4556 #1 0x00002b36f1ab34d9 in opal_memory_ptmalloc2_int_free (av=0x2aaab0c00020, mem=0x2aaab0c00a70) at ./malloc.c:4453 #2 0x00002b36f1ab1ce2 in opal_memory_ptmalloc2_free (mem=0x2aaab0c00a70) at ./malloc.c:3511 #3 0x00002b36f1ab0ca9 in opal_memory_linux_free_hook (__ptr=0x2aaab0c00a70, caller=0xa075c8) at ./hooks.c:705 #4 0x00000037b4a758a7 in free () from /lib64/libc.so.6 #5 0x0000000000a075c8 in CErrorReporter<std::basic_ostringstream<char, std::char_traits<char>, std::allocator<char> > > ::Clear () #6 0x0000000000a01eec in IPhreeqc::AccumulateLine () #7 0x0000000000a01180 in AccumulateLine () #8 0x0000000000a0078e in accumulatelinef_ () #9 0x0000000000576ce6 in initial_conditions_ () at ./PHREEQC-model.f:307 #10 0x0000000000577b3a in iphreeqc_main_ () at ./PHREEQC-model.f:505 #11 0x0000000000577fa1 in basicphreeqc_ () at ./PHREEQC-model.f:944 #12 0x00000000004b492a in phrqbl_ () at ./MULTI-COM.f:8371 #13 0x00000000004aa6e9 in smxmknp：ｑois_ () at ./MULTI-COM.f:5112 #14 0x00000000004a2c5e in solvenpois_ () at ./MULTI-COM.f:4276 #15 0x000000000049e731 in solducom_ () at ./MULTI-COM.f:3782 #16 0x000000000048b60c in MAIN () at ./MULTI-COM.f:1208 #17 0x0000000000481350 in main () #18 0x00000037b4a1d974 in __libc_start_main () from /lib64/libc.so.6 #19 0x0000000000481259 in _start () Best regard, Tetsuya Mishima
