Config holds global config info derived from config.json

func GetConfig

func GetConfig() *Config

GetConfig returns a shared instance of config

type Duration

type Duration struct {
	time.Duration
}

unfortunate hack to enable json parsing of human readable time strings see https://github.com/golang/go/issues/10275 code from https://stackoverflow.com/questions/48050945/how-to-unmarshal-json-into-durations

func (*Duration) UnmarshalJSON

func (d *Duration) UnmarshalJSON(b []byte) error

type GPUConfig

type GPUConfig struct {
	//number of threads in a workgroup
	GroupSize int `json:"groupSize"`
	//total number of threads
	Groups int `json:"groups"`
	//number of iterations within a thread
	Count uint32 `json:"count"`

	Disabled bool `json:"disabled"`
