....Pipelining in pipeline manner. One stage of computation makes a data to be transferred, and the latency of data transmission should be equal to the time needed to execute one computation stage (see Figure 5. 1) Active Message is implemented on CM 5, and on ATM and SCI based workstation clusters[11][12] 5.2.2 Illinois Fast Message and Fast Message 2.0 Fast Message[14] is very similar to Active Message in that the message header contains the address of user level handler. Because Fast Message targets not only MPP but also NOW, the userlevel handler can not be called timely when the message ....

....the data from communication link, no longer necessary. 3. Active Message scheme will not work on workstation environment at all. Because both the latency of message transmission and the time required for computation cannot be analyzed statically. Active Messages implemented on the top of ATM[11] needs message buffers for each user level process. Those buffers are allocated in user level address space, but the physical pages are pinned down so that it won t be swapped out when the process is scheduled out. When an Active Message arrives from network, the kernel moves the data from ....
