For the purpose of learning Java as a beginner, Hayabaya was developed as a rudimentary Microbenchmark project. The code performs arithmetic operations (+,-,/,*) on arrays of type:
Integer ints[]
Float floats[]
Long longs[]
Float floats[]And their primitive counterparts int[], long[], double[], float[]. The runtime for performing the arithmetic operations on the different types of arrays are measured.
Each of the operations are tested on all the datatypes for arrays of varying lenths as specified by a from, to, by expression, e.g, arrays of element lengths . 1,000 to 10,000 in steps of 1,000. In addition to the lenths, each element of the array is operated on a number of times called the CycleNumber which is defined just like the array length (from, to, by).
Hayabaya saves the results of the microbenchmark in CSV (Comma Separated Value) files with the following columns:
| Column name | Name | Datatype | IsBoxed | Operation | ReplicationNumber | ArrayLength | CycleNumber | Runtime |
|---|---|---|---|---|---|---|---|---|
| Description | Name of the system/CPU | Type of data tested | logical, Integer= True | (+,-,/,*) | What replication is run | Lenth of array | Times operation is done on an element | Runtime in ms |
| Example value | Inteli7 | Integer | True | ADD | 4 | 100,000 | 10,000 | 230 (ms) |
| Example value | AMDA4 | int | FALSE | DIVIDE | 5 | 100,000 | 20,000 | 175 (ms) |
