RESOURCE MACROS

SCORED LIBRARY(C)

RESOURCE MACROS

SYNOPSIS

SCORE_RSRC_NUM_NODES(MIN,MAX);
SCORE_RSRC_NUM_PROCS(N);
SCORE_RSRC_HOMO_NODES;
SCORE_RSRC_NUM_NETS(N);


DESCRIPTION

By using one or more resource macros in a library or user program, runtime resources can be constrained. There can be multiple resource macros in a program, however, contradictory macros produce link errors. These macros are evaluated to get resource information when scrun(1) invokes a user program on a local host. SCore-D resources can be better utilized by getting resource information prior to login.

SCORE_RSRC_NUM_NODES(MIN,MAX)

This macro gives a hint to the number of nodes to be allocated. Users who try to run a program with this macro must specify the number of nodes within the range MIN <= num_nodes <= MAX.

SCORE_RSRC_NUM_PROCS(N)

This macro constrains the number of processes in a host.

SCORE_RSRC_HOMO_NODES

When this macro is declared, only an homogeneous execution environment is allowed.

SCORE_RSRC_NUM_NETS(N)

This macro constrains the number of networks allocated.
