CPU vs. NIC one to one correspondence method for improving parallel processing performance in a small-way SMP cluster

We have studied various methods for improving the performance of SMP clusters. Most of them are using special hardware, non standard protocols, so that need special added library and complex programming, tending to raise their cost and to spoil their flexibility. To solve their problems we propose a CPU vs. NIC one to one correspondence method for improving parallel processing performance in a PC cluster, using comparatively simple method where transmitting NICs are fixedly assigned to CPUs one to one. So that the communication load between PCs can be balanced. Applying this method to parallel processing in a dual PC cluster, and comparing this method with conventional ordinary ones, we have obtained better result for some benchmarks.
