Benchmark Results for pmatrix.module 400 1

(For questions about these benchmarks send eMail to Claudio Fleiner)

This is the "real" Matrix Multiplaktion program pmatrix.sa running in parallel on a 4 processor Sparc running in parallel on a 4 processor Sparc. It multiplies two 400x400 matrices. Note that the equivalent C (matrix.c) and threaded C (pmatrix.c) are nearly an order of magnitude slower, unless they are optimized by hand (opt_matrix.c and popt_matrix.c).

Program compiler optimized hand optimized initialization time calculation time speedup
Sather 33.8 n/a 1.0 32.8
pSather 14.0 n/a 1.2 12.8 2.6
C 147.0 32.3 1.2 31.1
C + threads 42.0 13.9 1.3 12.6 2.5

Program	compiler optimized	hand optimized	initialization time	calculation time	speedup
Sather	33.8	n/a	1.0	32.8
pSather	14.0	n/a	1.2	12.8	2.6
C	147.0	32.3	1.2	31.1
C + threads	42.0	13.9	1.3	12.6	2.5

The reason for the non linear speedup is due to memory and cache effects. In fact, to get linear speedup the inner loops of the matrix multiplikation funtion have to make better usage of the cache.

The C and C++ version were compiled with GCC 2.7.1 and -O3.

Note that GCC cannot do much better without inter procedural analysis, as it has to prove that each write to one of the elements of the matrix does not change the size of any of the matrices involed, which could happen if the memory region of the three matrices overlap.
