40 * The PTLLND was designed to support Portals with
41 * Lustre and non-lustre UNLINK semantics.
42 * However for now the two targets are Cray Portals
43 * on the XT3 and Lustre Portals (for testing) both
44 * have Lustre UNLINK semantics, so this is defined
47 #define LUSTRE_PORTALS_UNLINK_SEMANTICS
49 #ifdef _USING_LUSTRE_PORTALS_
51 /* NIDs are 64-bits on Lustre Portals */
52 #define FMT_NID "%llu"
55 /* When using Lustre Portals Lustre completion semantics are imlicit*/
56 #define PTL_MD_LUSTRE_COMPLETION_SEMANTICS 0
58 #else /* _USING_CRAY_PORTALS_ */
60 /* NIDs are integers on Cray Portals */
64 /* When using Cray Portals this is defined in the Cray Portals Header*/

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