Inquiry mode or internuclear interruption（Inter-process Interrupt, IPI）Mode.
Especially, with the appearance of multinuclear and many-core, internuclear process communication is more frequent.
In the prior art, the flow that internuclear process communication is carried out by the way of poll is as follows：
S1, client process write partial write Message Payload into shared drive；
S2, client process write partial write message header into shared drive；
The message header of reading part in S3, server-side process poll shared drive；
S4, the discovery of server-side process have unread message then to read Message Payload.
The flow for carrying out internuclear process communication using internuclear interruption IPI is as follows：
H1, client process write partial write Message Payload into shared drive；
H2, client process write partial write message header into shared drive；
H3, client process calling system call, and are absorbed in client kernel, are cached in server-side message transmission（Message
Passing Buffer, MPB）The corresponding gap marker in middle write service end（channel id）, while update the writing position of MPB
（write pos）, the kernel interruption of triggering server-side；
H4, server-side kernel responds are interrupted, and channel id are obtained from MPB, to the corresponding locals of channel id
Lmp_endpoint sends a null message, and dispatch service end process is run；
H5, server-side process are during lmp_endpoint message is handled, the reading part in poll shared drive
Message header；
H6, discovery have unread message then to be handled.
In the prior art, when intercore communication is frequent, frequently carrying out internuclear interruption can cause in the frequent disengaging of receiving terminal process
Core causes message throughput low, when intercore communication is less, intercore communication is carried out by way of poll, excessive poll accounts for
With the processing capacity of CPU, cpu busy percentage is reduced.
It was found by the inventors of the present invention that polling communication and the applicable elements of internuclear interruption are not accounted in the prior art,
Lead to internuclear process communication inefficiency.

The device of end process.
Internuclear process communication is exactly the communication of process in different processor, and in multinuclear or many-core system, internuclear process is led to
Letter is very frequent, internuclear process in communication process sometimes as receiving terminal process, sometimes as transmitting terminal process, it is internuclear into
During Cheng Tongxin, message header and Message Payload are written in shared drive by transmitting terminal process in the process of running, then, are received
End process reads the message header and Message Payload of transmitting terminal process write-in from shared drive, so as to fulfill internuclear process communication,
Therefore, transmitting terminal, shared drive and receiving terminal have collectively constituted the message channel of internuclear process communication, and each message channel has
Unique gap marker.
102nd, when the handoff parameter of message in the message channel meets preset switching condition, the receiving terminal is led to
Believe pattern switching, the communication pattern is switched to the switching between poll pattern and internuclear interrupt mode.
Transmitting terminal process and the communication pattern of receiving terminal process have poll pattern and internuclear interrupt mode.
Poll pattern is exactly that receiving terminal process poll from shared drive reads the message header of transmitting terminal process write-in and disappears
Breath load.
Internuclear interrupt mode is exactly after transmitting terminal triggering receiving terminal kernel interrupts, and receiving terminal response is interrupted, and starts to read altogether
Enjoy the message header and Message Payload that transmitting terminal process is written in memory.
When message number is more, the handling capacity of message can be more improved using poll pattern, when message number is less, using core
Between interrupt mode can more improve the utilization rate of processor, so, receiving terminal, can be at two kinds after the message of monitoring message channel
It is switched in communication pattern, to improve the utilization rate of processor.
The handoff parameter of message can be weighed in preset time by the number of message.Such as：Preset time is 10
Second, predetermined times are 3 times, then poll pattern then may be used by 3 message in 10 seconds, if passing through 1 in 10 seconds
Message, then may be used internuclear interrupt mode.If the transmitting terminal process intercore communication pattern original with receiving terminal process is
Internuclear interrupt mode, receiving terminal in message channel is monitored in 10 seconds by 3 message, then communication pattern can be switched
To poll pattern, if transmitting terminal process is poll pattern with the original intercore communication pattern of receiving terminal process, receiving terminal is being supervised
It controls that no message passes through in 10 seconds in message channel or only 1 message passes through, is then switched to communication pattern internuclear
Interrupt mode.
103rd, the receiving terminal notify the transmitting terminal switch after communication pattern, and with the communication pattern after switching, into
The internuclear process communication of row.
Receiving terminal is notified the communication pattern after switching to transmitting terminal with the communication mould after switching after switch communication mode
Formula carries out internuclear process communication.
The embodiment of the present invention monitors the message channel of internuclear process communication using receiving terminal, and the message channel is sends
