| # Size distributions for memory functions under specific workloads |
| |
| This folder contains a set of files that are included from `libc/benchmarks/MemorySizeDistributions.cpp`. |
| |
| Offloading this data to individual files helps |
| - C++ editors (large arrays are usually not well handled by editors), |
| - and allows processing data by other tools to perform analysis or graph rendering. |
| |
| ## Format |
| |
| Most filenames are of the form `{MemoryFunctionName}{WorkloadID}.csv`. They contain a single line of comma separated real values representing the probability that a particular size occurs. e.g. |
| - `"0,1"` indicates that only the size `1` occurs, |
| - `"0.5,0.5"` indicates sizes `0` and `1` occur with the same frequency. |
| |
| These files usually contains sizes from `0` to `4096` inclusive. To save on space trailing zeros are discarded. |
| |
| ## Workloads |
| |
| As identified in the [automemcpy](https://research.google/pubs/pub50338/) paper: |
| - `GoogleA` <-> `service 4` |
| - `GoogleB` <-> `database 1` |
| - `GoogleD` <-> `storage` |
| - `GoogleL` <-> `logging` |
| - `GoogleM` <-> `service 2` |
| - `GoogleQ` <-> `database 2` |
| - `GoogleS` <-> `database 3` |
| - `GoogleU` <-> `service 3` |
| - `GoogleW` <-> `service 1` |
| |
| `Uniform384To4096` is an additional synthetic workload that simply returns a uniform repartition of the sizes from `384` to `4096` inclusive. |
| |
| ## Note |
| |
| Except for `GoogleD`, all distributions are gathered over one week worth of data. |
