Darshan version 3.1.6 is available for download here. This release addresses two bugs discovered in version 3.1.5:
- Bug fix in mapping of Darshan’s ‘MPI_File_read_all’ wrapper to the underlying MPI symbol. This results in a crash if a dynamically-linked application preloads the Darshan library and calls ‘MPI_File_read_all’.
- Bug fix for linker failures caused when an application links in a library that calls MPI externally (e.g., PETSc).
- Reported by Bilel Hadri
We highly recommend upgrading from version 3.1.5 to 3.1.6 particularly for deployments on production systems, as these bugs could be disruptive for end users.
