# This file contains global variable SCSCPservers which
# specifies hosts and ports to search for SCSCP services.
#
# 1) To avoid errors, all services must have the called
# SCSCP procedure installed and available under the
# same name.
#
# 2) SCSCPservers is a proper GAP list, so you can use GAP
# language constructions to generate it for a range
# of port numbers, for example, for specify SCSCP servers
# at the the beowulf cluster with hostnames from bwlf01 to
# bwlf16 and 4 cores per node you may use:
#
# nrnodes:=16;
# nrcores:=4;
# SCSCPservers := Cartesian (
# List( [1..nrnodes], i->
# Concatenation(
# "bwlf",
# Concatenation( List([1..2-Length(String(i))], i->"0") ),
# String(i) ) ),
# [26133 .. 26133+nrcores-1] );
#
# 3) It is better to arrange services in this list in a way
# that faster services and services with shorter latency
# will be located in the beginning of the list, this will
# optimise the initial placement of tasks and will speed
# up computation when the number of tasks is smaller than
# the number of services.
#
SCSCPservers:= List( [26133..26134], i-> [ "localhost", i ] );
