This priority is a number (0 - 100) determined by a scheduler (third party process) based on some basic priority the group has, e.g. we might want to give users in a specific group (e.g. promptana) a higher priority than users in other groups, and on the analysis of historical logging data (i.e. usage of CPU by the group in a previous time slot, as recorded in TPerfStats::WriteQueryLog()).

Currently the group priority is obtained by a query in a SQL DB table proofpriority, which has the format: CREATE TABLE proofpriority ( id INT NOT NULL PRIMARY KEY AUTO_INCREMENT, group VARCHAR(32) NOT NULL, priority INT )

Int_t TProofServ::SendAsynMessage	(	const char *	msg,
		Bool_t	lf = `kTRUE`
	)

virtual

Send an asychronous message to the master / client .

Masters will forward up the message to the client. The client prints 'msg' of stderr and adds a '
'/'' depending on 'lf' being kTRUE (default) or kFALSE. Returns the return value from TSocket::Send(TMessage &) .
