What is the maximum packet size for BMI?
Each BMI module is allowed to define its own maximum message size. See BMI_tcp_get_info, BMI_gm_get_info, and BMI_ib_get_info for examples of the maximum sizes that each of the existing modules support. The maximum should be reported when you issue a get_info call with the option set to BMI_CHECK_MAXSIZE. Higher level components of PVFS perform these checks in order to make sure that they don’t choose buffer sizes that are too large for the underlying network.
