Table 2.
Fine-grid parallel speedups for the p53 DBD and 70S ribosome with the SMP and TCP/IP methods, respectively
| Communication method (system) | 2 threads | 4 threads |
|---|---|---|
| SMP(p53 DBD) | 1.411 | 1.878 |
| TCP/IP(p53 DBD) | 1.880 | 3.826 |
| SMP(70S ribosome) | 1.538 | 1.721 |
| TCP/IP(70S ribosome) | 2.123 | 4.016 |
The speedups are represented as the ratios of the parallel to the serial computation throughputs. Four identical machines (Dell PE1950III) with two Intel Xeon 5140 processors with two cores were used in the comparison. There were two cores on each processor, which shared 4 MB of shared cache memory
