Known Issues
-
Infiniband users: Program 'crashes' with a segmentation fault when you run it with OPT.
The Infiniband interconnect does not support the fork() system call.
Edit ${OPT_ROOTDIR}/opt/etc/opt.conf and add the line:fork=no - Some compilers will optimize frame base registers in Fortran wrappers which can limit the ability of OPT to establish a stack for use in the callgraph and the timeline function details window. AMD Opteron and Intel EM64T are the only platforms on which this issue has arisen for some specific compiler (Portland Fortran 6 64 bit/SuSE 9.3) versions and glibc revisions. Further information is included in the OPTMPICompat.pdf document in the OPT installation. We are working with the compiler companies on these issues.
- MPI Compatibility - this version of OPT has been tested and is known to work with HP-MPI, Intel MPI, Open MPI, MPICH, MPICH 2, MPICH-GM, Bull MPI (1 and 2), Scali MPI, SCore and MVAPICH - the versions we have tested are listed in the OPTMPICompat.pdf document in the OPT installation. We are actively working to extend this compatibility list further, if your MPI is not listed, please contact support for further information.
- Some jobs may fail with the error "Failed to register with the server. The time on comp00 does not match the time on one or more other nodes.". See the Known Issues section in the User Guide for a resolution.
- If you select more than 3 or so PAPI metrics the sampler does not return any PAPI metric data. This is a limitation of the PAPI library.
