This page is to be used to track the progress of thread safety testing by the community members. Later we will use this (or another page) to jot down ideas that we think could improve OMPI's threadsafety performances.
- There are issues with concurrent thread access to a tcp endpoint. r15963 provides a workaround that prevents a segv when dereferencing a NULL frag pointer. But the underlying issue of multiple threads polling on the same endpoint still needs to be resolved. Hence, this note here.
- Possible comm creation performance improvement if we implemented an unexpected cid queue (get's rid of a collective).
- Intel Tests (We run these nightly via MTT. Here is a recent run)
- MPI: r15955 w/ --enable-mpi-threads
- Tests: All tests in the file 'all_tests_no_perf'
- System: Thor: Dual processor Dual processor Xeon(32 bit) w/ hyperthreading, running on 4 nodes, 2 ppn
- Network combinations used: "gm,self", "gm,sm,self", "openib,self", "tcp,openib,sm,self", "tcp,self", "tcp,sm,self"
- All tests in file 'all_tests_no_perf' pass.
- Threads Tests
- MPI: r15957 w/ --enable-mpi-threads
- Tests: built with pthreads and ran with defaults (no arguments)
- System: Thor: Dual processor Xeon(32 bit) w/ hyperthreading, running on 8 nodes, 2 ppn
