psb_cd_set_large_threshold -- Set threshold for index mapping switch

call psb_cd_set_large_threshold(ith)

Type:
Asynchronous.
On Entry
ith
the new threshold for communication descriptors.
Scope: global.
Type: required.
Intent: in.
Specified as: an integer value greater than zero.
Note: the threshold value is only queried by the library at the time a call to psb_cdall is executed, therefore changing the threshold has no effect on communication descriptors that have already been initialized.
