Method and system for requester virtual cut through
First Claim
1. A communication adapter comprising:
- a buffer configured to store a first sub-unit and a second sub-unit of a message;
transmitting process logic operatively connected to the buffer, comprising;
a collect buffer unit module configured to receive, from a transmitting device, a request to send the message;
a virtual kick module configured to temporarily store the request once the request is entirely received;
a queue pair fetch module configured to obtain, from the transmitting device, a queue pair status information corresponding to the request;
a direct memory access (DMA) module configured to obtain the message from a location in memory of the transmitting device, wherein the location is specified in the request,a sub-unit builder module configured to;
modify a maximum transfer unit (MTU) to obtain a modified MTU;
divide the message to obtain the first sub-unit based on the modified MTU;
iteratively increase the MTU for transmitting a plurality of intermediate sub-units of the message until an MTU limit is reached to obtain a plurality of iteratively increased MTUs; and
divide the message to obtain the plurality of intermediate sub-units using the plurality of iteratively increased MTUs; and
a port configured to;
transmit, to a receiving system, the first sub-unit of the message using the modified MTU;
transmit, to the receiving system, the plurality of intermediate sub-units of the message, wherein the plurality of intermediate sub-units are transmitted after the first sub-unit and before the second sub-unit; and
transmit, to the receiving system, the second sub-unit to the receiving system using a full path MTU.

Abstract
A method for transmitting a message includes a communication adapter receiving, from a transmitting device, a request to send the message. The method further includes modifying a maximum transfer unit (MTU) to obtain a modified MTU, transmitting, from the communication adapter to a receiving system, a first sub-unit of the message using the modified MTU, iteratively increasing the MTU for transmitting intermediate sub-units of the message until an MTU limit is reached, and transmitting, to the receiving system, the intermediate sub-units of the message. The intermediate sub-units are transmitted after the first sub-unit and before a second sub-unit. The method further includes transmitting, from the communication adapter to the receiving system, the second sub-unit to the receiving system using a full path MTU.
