Linpack Highly Parallel Computing Benchmark
The Linpack Highly Parallel Computing benchmark is designed to explore the scalability of parallel systems. In this benchmark, we are allowed to pick the size of the matrix (N), and hence the amount of work done by each processor. The available physical memory in the system under test provides a rough upper bound on the value for N.

N_{max} : The matrix size (N) that gives the highest Gflops for some number of CPUs.
R_{max} : The Gflops achieved for the N_{max} size matrix.
N_{1/2} : The matrix size that achieves half the rated R_{max} Gflops

PVMPOV measures the performance by Ray Tracing tasks, it uses PVM to perform message passing.
Skyvase  The image we going to render
we use following options for the benchmarking:
pvmpov +iskyvase.pov +w1600 +h1200
\
+FT +vl x d +a0.300 q9 \
mv2.0 b1000 nw48 nh36
nt34 \
L/home/carlos/pvmpov3_1e_1/povray31/include
which means we render a 1600x1200 image by the information in iskyvase.pov using 34 CPUs, and split the image into rendering blocks sized 48 x 36.
