The performance achieved by this software package on a few machine |
| 23 |
configurations is shown below. These results are only provided for |
| 24 |
illustrative purposes. By the time you read this, those systems |
| 25 |
have changed, they may not even exist anymore and one can surely |
| 26 |
not exactly reproduce the state in which these machines were when |
| 27 |
those measurements have been obtained. To obtain accurate figures |
| 28 |
on your system, it is absolutely necessary to |
| 29 |
<A HREF = "software.html">download the software</A> and run it there. |

processors) and nodes. The first row for example is denoted by 1 / 1, |
| 158 |
i.e., 1 cpu / 1 node. Rmax is given in Gflops, and the value of Nmax |
| 159 |
in fact corresponds to 351 Mb per cpu for all machine configurations.<BR><BR> |

For shown the , the efficiency cpu been |

using performance by on cpu. is , |
| 215 |
since CXML multiply was at 1.24 |
| 216 |
for matrix on cpu, it have difficult a |
| 217 |
Linpack implementation achieve more |
| 218 |
1.136 on same For load (as the 351 |
| 219 |
per for ), HPL almost as should. |
