gotools
High Performance Computing Go
Install
Package gotools is a set of multipurpose libraries modified for High Performance Computing in Go
Install
go get github.com/zerjioang/gotools
Features
Following a list of implemented features are described
| Feature | Description |
|---|---|
IsIpv4 |
Ipv4 string address validator |
Ip2intLow |
Converts given IP address string to its numeric representation |
IpToIntAssemblyAmd64 |
Converts given IP address string to its numeric representation using amd64 Go assembly code |
Other Libraries
- A deadly simple thread-safe, zero-alloc event bus for Golang (https://github.com/zerjioang/go-bus)
- A pure go High Performance Finite State Machine with GraphViz support (https://github.com/zerjioang/go-fsm)
Development
Inline anaylsis
go test ./... -gcflags="-m=2" 2>&1 | grep "too complex"
Bound check analysis
go test ./... -gcflags="-d=ssa/check_bce/debug=1"
You can do an early bounds check deep into the slice to avoid multiple bounds checks further on. If that won't work:
- propagate constants
- unroll loops
- reuse previously allocated vars
This can make the code super ugly! a dozen lines becomes a few hundred. but... 80% throughput boost!
Contributing
Everybody is welcome to contribute to gotools. And any other comments will be very appreciate.
