"bwa" sample introduction
|
|
==============
|
|
|
|
This sample demonstrates how to build [bwa](https://github.com/lh3/bwa) into
|
|
WebAssembly with simd support and run it with iwasm.
|
|
|
|
## Preparation
|
|
|
|
please refer to [installation instructions](../README.md).
|
|
|
|
## Build
|
|
|
|
``` shell
|
|
$ mkdir build && cd build
|
|
$ cmake ..
|
|
$ make
|
|
# to verify
|
|
$ ls bwa.wasm
|
|
```
|
|
|
|
## Download sample data
|
|
|
|
Download the bwa-0.7.15 binary package from
|
|
[such an address](https://sourceforge.net/projects/bio-bwa/files/bwakit/bwakit-0.7.15_x64-linux.tar.bz2/download),
|
|
a sample data file named **hs38DH.fa** will be used later.
|
|
|
|
If want more data, please refer to http://hgdownload.cse.ucsc.edu/goldenpath/hg19/bigZips/
|
|
|
|
## Run workload
|
|
|
|
Firstly please build iwasm with simd support:
|
|
|
|
``` shell
|
|
$ cd <wamr dir>/product-mini/platforms/linux/
|
|
$ mkdir build && cd build
|
|
$ cmake ..
|
|
$ make
|
|
```
|
|
|
|
Then compile wasm file to aot file and run:
|
|
|
|
``` shell
|
|
$ cd <wamr dir>/samples/workload/bwa/build
|
|
$ <wamr dir>/wamr-compiler/build/wamrc -o bwa.aot bwa.wasm
|
|
$ <wamr dir>/product-mini/platforms/linux/iwasm --dir=. bwa.aot index hs38DH-extra.fa
|
|
```
