| 19 | 1 | equemene | <LI>Download the <A HREF="hpl.tgz">tar-gzipped file</A>, issue then |
| 20 | 1 | equemene | "gunzip hpl.tgz; tar -xvf hpl.tar" and this should create an hpl |
| 21 | 1 | equemene | directory containing the distribution. We call this directory the |
| 22 | 1 | equemene | top level directory. |
| 23 | 1 | equemene | |
| 24 | 1 | equemene | <LI>Create a file Make.<arch> in the top-level directory. |
| 25 | 1 | equemene | For this purpose, you may want to re-use one contained in the |
| 26 | 1 | equemene | setup directory. This Make.<arch> file essentially contains |
| 27 | 1 | equemene | the compilers, libraries, and their paths to be used on your system. |
| 28 | 1 | equemene | |
| 29 | 1 | equemene | <LI>Type "make arch=<arch>". This should create an executable |
| 30 | 1 | equemene | in the bin/<arch> directory called xhpl. For example, on our |
| 31 | 1 | equemene | Linux PII cluster, I create a file called Make.Linux_PII in the |
| 32 | 1 | equemene | top-level directory. Then, I type "make arch=Linux_PII". This |
| 33 | 1 | equemene | creates the executable file bin/Linux_PII/xhpl. |
| 34 | 1 | equemene | |
| 35 | 1 | equemene | <LI>Quick check: run a few tests (assuming you have 4 nodes for
|
| 36 | 1 | equemene | interactive use) by issuing the following commands from the top |
| 37 | 1 | equemene | level directory: "cd bin/<arch> ; mpirun -np 4 xhpl". This |
| 38 | 1 | equemene | should produce quite a bit of meaningful output on the screen. |
| 39 | 1 | equemene | |
| 40 | 1 | equemene | <LI>Most of the performance parameters can be tuned, by modifying
|
| 41 | 1 | equemene | the input file bin/<arch>/HPL.dat. See the |
| 42 | 1 | equemene | <A HREF = "tuning.html">tuning page</A> or the TUNING file in the |
| 43 | 1 | equemene | top-level directory. |
