Member Function Documentation

void LangmuirCore::NodeFileParser::clear

(

)

clear the records

const QStringList& LangmuirCore::NodeFileParser::cpus

(

)

get the hostnames

void LangmuirCore::NodeFileParser::createNode	(	const QString &	name,
		int	cores = 0,
		QList< int >	gpus = QList< int >()
	)

add cpu to records

Parameters

name	name of cpu
cores	number of cores
gpus	list of GPU ids

int LangmuirCore::NodeFileParser::GPUid	(	const QString &	name,
		int	i
	)

get the ith gpu id on host

Parameters

name	hostname
i	index

const QList<int>& LangmuirCore::NodeFileParser::gpus

(

const QString &

name

)

get the number of gpus on host

Parameters

name

hostname

const QString& LangmuirCore::NodeFileParser::hostName

(

)

get the hostname of this cpu

int LangmuirCore::NodeFileParser::numCPUs

(

)

get the number of hosts

int LangmuirCore::NodeFileParser::numGPUS

(

)

get the number of gpus on all hosts

int LangmuirCore::NodeFileParser::numGPUs

(

const QString &

name

)

get the number of gpus on host

Parameters

name

hostname

int LangmuirCore::NodeFileParser::numProc

(

)

get the number of processes on all hosts

int LangmuirCore::NodeFileParser::numProc

(

const QString &

name

)

get the number of processes on host

Parameters

name

hostname

bool LangmuirCore::NodeFileParser::parse ( QString &  filename, bool  ignoreCores = false, bool  ignoreGPUs = true  )

private

parse NODEFILE or GPUFILE

Parameters

filename	name of file to parse
ignoreCores	do not parse core information
ignoreGPUs	do not parse gpu information

Returns

true if success

const QMap<QString,int>& LangmuirCore::NodeFileParser::procs

(

)

get the number of processes on all hosts

void LangmuirCore::NodeFileParser::setDefault

(

)

set the default based on QThreadPool and hostname

void LangmuirCore::NodeFileParser::setHostName

(

const QString &

hostName

)

set the name of this CPU

Parameters

hostName

host name string

void LangmuirCore::NodeFileParser::setHostName

(

)

set the name of this CPU using boost::asio::ip::hostname()

void LangmuirCore::NodeFileParser::setPaths	(	const QString &	nodefile = "",
		const QString &	gpufile = ""
	)

aquire the paths of the GPUFILE and the NODEFILE and parse them

Parameters

nodefile	path to NODEFILE
gpufile	path to GPUFILE

If nodefile is empty the enviroment variable PBS_NODEFILE is used. If gpufile is empty, the enviroment variable PBS_GPUFILE is used. If both paths remain empty, then setDefault() is used.
