42 * The PTLLND was designed to support Portals with
43 * Lustre and non-lustre UNLINK semantics.
44 * However for now the two targets are Cray Portals
45 * on the XT3 and Lustre Portals (for testing) both
46 * have Lustre UNLINK semantics, so this is defined

54 /* NIDs are 64-bits on Lustre Portals */
58 /* When using Lustre Portals Lustre completion semantics are imlicit*/

77 * The Cray Portals has no maximum number of IOVs. The
78 * maximum is limited only my memory and size of the
79 * int parameters (2^31-1).
80 * Lustre only really require that the underyling
81 * implemenation to support at least LNET_MAX_IOV,
82 * so for Cray portals we can safely just use that
