1# Size distributions for memory functions under specific workloads 2 3This folder contains a set of files that are included from `libc/benchmarks/MemorySizeDistributions.cpp`. 4 5Offloading this data to individual files helps 6 - C++ editors (large arrays are usually not well handled by editors), 7 - and allows processing data by other tools to perform analysis or graph rendering. 8 9 ## Format 10 11Most 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. 12 - `"0,1"` indicates that only the size `1` occurs, 13 - `"0.5,0.5"` indicates sizes `0` and `1` occur with the same frequency. 14 15 These files usually contains sizes from `0` to `4096` inclusive. To save on space trailing zeros are discarded. 16 17 ## Workloads 18 19As identified in the [automemcpy](https://research.google/pubs/pub50338/) paper: 20 - `GoogleA` <-> `service 4` 21 - `GoogleB` <-> `database 1` 22 - `GoogleD` <-> `storage` 23 - `GoogleL` <-> `logging` 24 - `GoogleM` <-> `service 2` 25 - `GoogleQ` <-> `database 2` 26 - `GoogleS` <-> `database 3` 27 - `GoogleU` <-> `service 3` 28 - `GoogleW` <-> `service 1` 29 30`Uniform384To4096` is an additional synthetic workload that simply returns a uniform repartition of the sizes from `384` to `4096` inclusive. 31 32## Note 33 34Except for `GoogleD`, all distributions are gathered over one week worth of data.
