Kor - OTF2 support assumes a shared parallel filesystem, and that the file doesn’t already exist. All processes also need to know their MPI ranks.
a) are you on a shared filesystem? You can change the path to the archive with the APEX_OTF2_ARCHIVE_PATH environment variable. (See http://khuck.github.io/xpress-apex/environment/) b) does the path already exist? Please delete it before the run c) How are you configuring/launching HPX? Is this application launched with mpirun/mpiexec/jsrun/srun? d) which version of HPX and/or APEX are you using? Thanks!
