| 1 | # Documentation Mapping DIS Stressmark Parameters to WSS | ||
| 2 | |||
| 3 | ## Field | ||
| 4 | 1 allocation in main() | ||
| 5 | f = 1st input param | ||
| 6 | |||
| 7 | sizeof(unsigned char) * f | ||
| 8 | |||
| 9 | ## Matrix | ||
| 10 | 6 allocations in main(), 7 allocations in biConjugateGradient() | ||
| 11 | |||
| 12 | *Allocations in main()* | ||
| 13 | dim = 2nd input param | ||
| 14 | numberNonzero = 3nd input param | ||
| 15 | |||
| 16 | sizeof(double) * (dim^2+3dim+numberNonzero) + sizeof(int) * (2dim+1+numberNonzero) | ||
| 17 | |||
| 18 | *Allocations in biConjugateGradient()* | ||
| 19 | sizeof(double) * 7dim | ||
| 20 | |||
| 21 | ## Neighborhood | ||
| 22 | 1 allocation in createImage, 2 allocations in neighborhoodCalculation | ||
| 23 | |||
| 24 | *Allocations in createImage()* | ||
| 25 | dimension = 3rd input param | ||
| 26 | |||
| 27 | sizeof(short int) * dimension^2 | ||
| 28 | |||
| 29 | *Allocations in neighborhoodCalculation()* | ||
| 30 | bitDepth = 2nd param | ||
| 31 | |||
| 32 | sizeof(int) * (2^(bitDepth + 1) - 1) | ||
| 33 | |||
| 34 | ## Pointer | ||
| 35 | n = 5th input param | ||
| 36 | f = 1st input param | ||
| 37 | |||
| 38 | sizeof(unsigned int) * 4n + sizeof(int) * f | ||
| 39 | |||
| 40 | ## Transitive | ||
| 41 | n = 1st input param | ||
| 42 | |||
| 43 | sizeof(unsigned int) * 2n^2 | ||
| 44 | |||
| 45 | ## Update | ||
| 46 | f = 1st input param | ||
| 47 | |||
| 48 | sizeof(int) * f | ||
| 49 | |||
| 50 | ## Testplan | ||
| 51 | *Problem!* Larger WSS = more computations | ||
| 52 | Use testcase #1 for non-specified parameters | ||
| 53 | Below math computed for x86_64 | ||
| 54 | - Test WSS at powers of 2: 16 KiB, 32, 64, 128, 256, 512, 1MiB, 2, 4, 8, 16, 32 | ||
| 55 | - For each WSS, measure cache allocation of 0, 1, 2, 4, 8, 16 | ||
| 56 | |||
| 57 | ### Field | ||
| 58 | Just vary first param | ||
| 59 | |||
| 60 | f = WSS | ||
| 61 | |||
| 62 | ### Matrix | ||
| 63 | 0.3 - 16% number nonzero | ||
| 64 | - Fixed at 8% | ||
| 65 | Just vary dim (matrix size) | ||
| 66 | |||
| 67 | sizeof(double) * (dim^2+10dim+numberNonzero) + sizeof(int) * (2dim+1+numberNonzero) = WSS | ||
| 68 | |||
| 69 | |||
| 70 | ### Neighborhood | ||
| 71 | 8 or 15 bit depth | ||
| 72 | - Fix at 12? | ||
| 73 | Just vary dim (image size) | ||
| 74 | |||
| 75 | ### Pointer | ||
| 76 | 10 for n | ||
| 77 | Just vary f | ||
| 78 | |||
| 79 | ### Transitive | ||
| 80 | Just vary n | ||
| 81 | |||
| 82 | ### Update | ||
| 83 | Just vary f | ||
