Hi, uDAPL Developers: I have a system running uDAPL 2.0, the dat_ia_query() return the provider attributes, the 'max_private_data_size' is only 48. The standard 2.0 says that private data size is at least 64 bytes: Is there any way to tune private data size to 128 bytes, or at least 64 bytes ? Thanks. CQ Tang, HP-MPI team
