| 82 | * Aggregate clat samples to report percentile(s) of them. |
| 83 | * |
| 84 | * EXECUTIVE SUMMARY |
| 85 | * |
| 86 | * FIO_IO_U_PLAT_BITS determines the maximum statistical error on the |
| 87 | * value of resulting percentiles. The error will be approximately |
| 88 | * 1/2^(FIO_IO_U_PLAT_BITS+1) of the value. |
| 89 | * |
| 90 | * FIO_IO_U_PLAT_GROUP_NR and FIO_IO_U_PLAT_BITS determine the maximum |
| 91 | * range being tracked for latency samples. The maximum value tracked |
| 92 | * accurately will be 2^(GROUP_NR + PLAT_BITS -1) microseconds. |
| 93 | * |
| 94 | * FIO_IO_U_PLAT_GROUP_NR and FIO_IO_U_PLAT_BITS determine the memory |
| 95 | * requirement of storing those aggregate counts. The memory used will |
| 96 | * be (FIO_IO_U_PLAT_GROUP_NR * 2^FIO_IO_U_PLAT_BITS) * sizeof(int) |
| 97 | * bytes. |
| 98 | * |
| 99 | * FIO_IO_U_PLAT_NR is the total number of buckets. |
| 100 | * |
| 101 | * DETAILS |
| 102 | * |
| 103 | * Suppose the clat varies from 0 to 999 (usec), the straightforward |
| 104 | * method is to keep an array of (999 + 1) buckets, in which a counter |
| 105 | * keeps the count of samples which fall in the bucket, e.g., |
| 106 | * {[0],[1],...,[999]}. However this consumes a huge amount of space, |
| 107 | * and can be avoided if an approximation is acceptable. |
| 108 | * |
| 109 | * One such method is to let the range of the bucket to be greater |
| 110 | * than one. This method has low accuracy when the value is small. For |
| 111 | * example, let the buckets be {[0,99],[100,199],...,[900,999]}, and |
| 112 | * the represented value of each bucket be the mean of the range. Then |
| 113 | * a value 0 has an round-off error of 49.5. To improve on this, we |
| 114 | * use buckets with non-uniform ranges, while bounding the error of |
| 115 | * each bucket within a ratio of the sample value. A simple example |
| 116 | * would be when error_bound = 0.005, buckets are { |
| 117 | * {[0],[1],...,[99]}, {[100,101],[102,103],...,[198,199]},.., |
| 118 | * {[900,909],[910,919]...} }. The total range is partitioned into |
| 119 | * groups with different ranges, then buckets with uniform ranges. An |
| 120 | * upper bound of the error is (range_of_bucket/2)/value_of_bucket |
| 121 | * |
| 122 | * For better efficiency, we implement this using base two. We group |
| 123 | * samples by their Most Significant Bit (MSB), extract the next M bit |
| 124 | * of them as an index within the group, and discard the rest of the |
| 125 | * bits. |
| 126 | * |
| 127 | * E.g., assume a sample 'x' whose MSB is bit n (starting from bit 0), |
| 128 | * and use M bit for indexing |
| 129 | * |
| 130 | * | n | M bits | bit (n-M-1) ... bit 0 | |
| 131 | * |
| 132 | * Because x is at least 2^n, and bit 0 to bit (n-M-1) is at most |
| 133 | * (2^(n-M) - 1), discarding bit 0 to (n-M-1) makes the round-off |
| 134 | * error |
| 135 | * |
| 136 | * 2^(n-M)-1 2^(n-M) 1 |
| 137 | * e <= --------- <= ------- = --- |
| 138 | * 2^n 2^n 2^M |
| 139 | * |
| 140 | * Furthermore, we use "mean" of the range to represent the bucket, |
| 141 | * the error e can be lowered by half to 1 / 2^(M+1). By using M bits |
| 142 | * as the index, each group must contains 2^M buckets. |
| 143 | * |
| 144 | * E.g. Let M (FIO_IO_U_PLAT_BITS) be 6 |
| 145 | * Error bound is 1/2^(6+1) = 0.0078125 (< 1%) |
| 146 | * |
| 147 | * Group MSB #discarded range of #buckets |
| 148 | * error_bits value |
| 149 | * ---------------------------------------------------------------- |
| 150 | * 0* 0~5 0 [0,63] 64 |
| 151 | * 1* 6 0 [64,127] 64 |
| 152 | * 2 7 1 [128,255] 64 |
| 153 | * 3 8 2 [256,511] 64 |
| 154 | * 4 9 3 [512,1023] 64 |
| 155 | * ... ... ... [...,...] ... |
| 156 | * 18 23 17 [8838608,+inf]** 64 |
| 157 | * |
| 158 | * * Special cases: when n < (M-1) or when n == (M-1), in both cases, |
| 159 | * the value cannot be rounded off. Use all bits of the sample as |
| 160 | * index. |
| 161 | * |
| 162 | * ** If a sample's MSB is greater than 23, it will be counted as 23. |
