....execution continues after the faulting access check. The protocol that maintains the consistency between the cached copies and the home node also implements home node migration and switches between read only and shared states. The protocol s implementation is very similar to that of JUMP (see [8]) 3.4.2 Retrieving A Chunk Of An Array Accessing an array element is similar to accessing an object field, except that the array is divided into 256 byte chunks and each chunk is individually managed. The access check code for arrays is therefore changed to not only take the address of the ....

....when two or more processors write to the same page within two barriers. It does not work on applications that use locks either. We also tested the performance of JIAJIA V2.1 and compared it with that of JUMP, using the same testing environment mentioned in Section 5. The results are summarized in [16], and it shows that JUMP outperforms JIAJIA V2.1 in all applications except RX, in which JUMP loses by 2.0 22.9 . Thus the migrating home protocol in JUMP is more efficient than the home migration protocol in JIAJIA V2.1 in general. 8. CONCLUSIONS This paper has proposed the migrating home ....

....Moreover, DP adopts a peer to peer model like the MPI, eliminating the need to perform binding and listening between endpoints of a communication channel. However, it is easy to build up this socket layer on top of DP in order to cope with user convenience and program compatibility issues [3]. 3. Directed Point Cost Model We propose a communication cost model that can be used as a versatile tool for performance analysis evaluation and algorithm design. By providing a set of model parameters that captures the crucial performance characteristics of the cluster network together with ....
