Defines remote memory access operations.
◆ uct_ep_put_short()
◆ uct_ep_put_bcopy()
◆ uct_ep_put_zcopy()
The input data in iov array of uct_iov_t structures sent to remote address ("gather output"). Buffers in iov are processed in array order. This means that the function complete iov[0] before proceeding to iov[1], and so on.
- Parameters
-
[in] | ep | Destination endpoint handle. |
[in] | iov | Points to an array of uct_iov_t structures. The iov pointer must be a valid address of an array of uct_iov_t structures. A particular structure pointer must be a valid address. A NULL terminated array is not required. |
[in] | iovcnt | Size of the iov data uct_iov_t structures array. If iovcnt is zero, the data is considered empty. iovcnt is limited by uct_iface_attr::cap::put::max_iov. |
[in] | remote_addr | Remote address to place the iov data. |
[in] | rkey | Remote key descriptor provided by uct_rkey_unpack |
[in] | comp | Completion handle as defined by uct_completion_t. |
- Returns
- UCS_INPROGRESS Some communication operations are still in progress. If non-NULL comp is provided, it will be updated upon completion of these operations.
◆ uct_ep_get_short()
◆ uct_ep_get_bcopy()
◆ uct_ep_get_zcopy()
The output data in iov array of uct_iov_t structures received from remote address ("scatter input"). Buffers in iov are processed in array order. This means that the function complete iov[0] before proceeding to iov[1], and so on.
- Parameters
-
[in] | ep | Destination endpoint handle. |
[in] | iov | Points to an array of uct_iov_t structures. The iov pointer must be a valid address of an array of uct_iov_t structures. A particular structure pointer must be a valid address. A NULL terminated array is not required. |
[in] | iovcnt | Size of the iov data uct_iov_t structures array. If iovcnt is zero, the data is considered empty. iovcnt is limited by uct_iface_attr::cap::get::max_iov. |
[in] | remote_addr | Remote address of the data placed to the iov. |
[in] | rkey | Remote key descriptor provided by uct_rkey_unpack |
[in] | comp | Completion handle as defined by uct_completion_t. |
- Returns
- UCS_INPROGRESS Some communication operations are still in progress. If non-NULL comp is provided, it will be updated upon completion of these operations.
