Modifying Codes
|
||
|
|
------------------
|
||
|
|
|
||
|
|
Parameters such as the input sizes, data type, and threshold for GPU-CPU output comparison can be modified using constants
|
||
|
|
within the codes and .h files. After modifying, run `make clean` then `make` on relevant code for modifications to take effect in resulting executable.
|
||
|
|
|
||
|
|
###Parameter Configuration:
|
||
|
|
|
||
|
|
####Input Size:
|
||
|
|
By default the `STANDARD_DATASET` as defined in the `.cuh/.h` file is used as the input size. The dataset choice can be adjusted from `STANDARD_DATASET` to other
|
||
|
|
options (`MINI_DATASET`, `SMALL_DATASET`, etc) in the `.cuh/.h` file, the dataset size can be adjusted by defining the input size manually in the `.cuh/.h` file, or
|
||
|
|
the input size can be changed by simply adjusting the `STANDARD_DATASET` so the program has different input dimensions.
|
||
|
|
|
||
|
|
###`DATA_TYPE` (in `.cuh/.h` files):
|
||
|
|
By default, the `DATA_TYPE` used in these codes are `float` that can be changed to `double` by changing the `DATA_TYPE` typedef. Note that in OpenCL, the `DATA_TYPE` needs to be changed in both the .h and .cl files, as the .cl files contain the kernel code and is compiled separately at run-time.
|
||
|
|
|
||
|
|
|
||
|
|
####Other available options
|
||
|
|
|
||
|
|
These are passed as macro definitions during compilation time
|
||
|
|
(e.g `-Dname_of_the_option`) or can be added with a `#define` to the code.
|
||
|
|
- `POLYBENCH_STACK_ARRAYS` (only applies to allocation on host):
|
||
|
|
use stack allocation instead of malloc [default: off]
|
||
|
|
- `POLYBENCH_DUMP_ARRAYS`: dump all live-out arrays on stderr [default: off]
|
||
|
|
- `POLYBENCH_CYCLE_ACCURATE_TIMER`: Use Time Stamp Counter to monitor
|
||
|
|
the execution time of the kernel [default: off]
|
||
|
|
- `MINI_DATASET`, `SMALL_DATASET`, `STANDARD_DATASET`, `LARGE_DATASET`,
|
||
|
|
`EXTRALARGE_DATASET`: set the dataset size to be used
|
||
|
|
[default: `STANDARD_DATASET`]
|
||
|
|
|
||
|
|
- `POLYBENCH_USE_C99_PROTO`: Use standard C99 prototype for the functions.
|
||
|
|
|
||
|
|
- `POLYBENCH_USE_SCALAR_LB`: Use scalar loop bounds instead of parametric ones.
