| SciMark2 (C version) |
| |
| This is an ANSI C version of the SciMark2 benchmark, |
| translated from the original Java sources. The intent |
| in making this benchmark available in C is for mainly |
| for performance comparisons. For more information |
| about SciMark, see http://math.nist.gov/scimark. |
| |
| Results of this benchmark can be sent to pozo@nist.gov. |
| |
| The program is split up into the main driver (scimark2.c) and |
| kernel routines. A sample makefile is included; |
| however, one could simply write |
| |
| |
| > cc -o scimark2 -O *.c |
| |
| and then run |
| |
| > scimark2 |
| |
| This produces an output similar to |

| Composite Score: 65.56 |
| FFT Mflops: 63.38 (N=1024) |
| SOR Mflops: 124.80 (100 x 100) |
| MonteCarlo: Mflops: 16.05 |
| Sparse matmult Mflops: 59.15 (N=1000, nz=5000) |
| LU Mflops: 64.40 (M=100, N=100) |
| 0:29.62 Elapsed, 29.620 user sec, 0.010 sys sec, 100.0% utilization. |
| |
| |
| |
| The first SciMark number reported is the composite score, followed |
| by the an approximate Mflop rate for each kernel. |
| |
| |
| To run the "large" version of this benchmark (with data structures |
| that typically do not fit in cache) use |
| |
| >scimark2 -large |
