  • Add a new internal I/O driver, named pncio, which implements several strategies for performance improvement.
  • Add support of intra-node aggregation for read requests

CHECK_FATAL_ERR goto fn_exit instead of MPI_Abort
CHECK_ERR_ALL calls MPI_Allreduce() to check errors collectively.
CHECK_EXP_ERR_ALL is similar but checks a given, expected error code
add two constants for testing collective and independent modes
fix default output file name
silence label followed by a declaration is a C23 extension
Also print hint cb_node_list and nc_ina_node_list
Adff print of 2 Cray specific hints
