#define UCT_IFACE_FLAG_ATOMIC_CPU UCS_BIT(30) |
Atomic communications are consistent with respect to CPU operations.
#define UCT_IFACE_FLAG_ATOMIC_DEVICE UCS_BIT(31) |
Atomic communications are consistent only with respect to other atomics on the same device.
#define UCT_IFACE_FLAG_ERRHANDLE_SHORT_BUF UCS_BIT(32) |
Invalid buffer for short operation
#define UCT_IFACE_FLAG_ERRHANDLE_BCOPY_BUF UCS_BIT(33) |
Invalid buffer for buffered operation
#define UCT_IFACE_FLAG_ERRHANDLE_ZCOPY_BUF UCS_BIT(34) |
Invalid buffer for zero copy operation
#define UCT_IFACE_FLAG_ERRHANDLE_AM_ID UCS_BIT(35) |
Invalid AM id on remote
#define UCT_IFACE_FLAG_ERRHANDLE_REMOTE_MEM UCS_BIT(36) |
Remote memory access
#define UCT_IFACE_FLAG_ERRHANDLE_BCOPY_LEN UCS_BIT(37) |
Invalid length for buffered operation
#define UCT_IFACE_FLAG_ERRHANDLE_PEER_FAILURE UCS_BIT(38) |
Remote peer failures/outage
#define UCT_IFACE_FLAG_EP_CHECK UCS_BIT(39) |
Endpoint check
#define UCT_IFACE_FLAG_CONNECT_TO_IFACE UCS_BIT(40) |
Supports connecting to interface
#define UCT_IFACE_FLAG_CONNECT_TO_EP UCS_BIT(41) |
Supports connecting to specific endpoint
#define UCT_IFACE_FLAG_CONNECT_TO_SOCKADDR UCS_BIT(42) |
Supports connecting to sockaddr
#define UCT_IFACE_FLAG_AM_DUP UCS_BIT(43) |
Active messages may be received with duplicates This happens if the transport does not keep enough information to detect retransmissions
#define UCT_IFACE_FLAG_CB_SYNC UCS_BIT(44) |
Interface supports setting a callback which is invoked only from the calling context of uct_worker_progress()
#define UCT_IFACE_FLAG_CB_ASYNC UCS_BIT(45) |
Interface supports setting a callback which will be invoked within a reasonable amount of time if uct_worker_progress() is not being called. The callback can be invoked from any progress context and it may also be invoked when uct_worker_progress() is called.
#define UCT_IFACE_FLAG_EP_KEEPALIVE UCS_BIT(46) |
Transport endpoint has built-in keepalive feature, which guarantees the error callback on the transport interface will be called if the communication channel with remote peer is broken, even if there are no outstanding send operations
#define UCT_IFACE_FLAG_TAG_EAGER_SHORT UCS_BIT(50) |
Hardware tag matching short eager support
#define UCT_IFACE_FLAG_TAG_EAGER_BCOPY UCS_BIT(51) |
Hardware tag matching bcopy eager support
#define UCT_IFACE_FLAG_TAG_EAGER_ZCOPY UCS_BIT(52) |
Hardware tag matching zcopy eager support
#define UCT_IFACE_FLAG_TAG_RNDV_ZCOPY UCS_BIT(53) |
Hardware tag matching rendezvous zcopy support
