Bug ID: 97331
Summary: [nvptx] Provide GCN_NUM_TEAMS/GCN_NUM_THREADS
equivalent
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: libgomp
Assignee: unassigned at gcc dot gnu.org
Reporter: vries at gcc dot gnu.org
CC: jakub at gcc dot gnu.org
Target Milestone: ---
When looking at the gcn plugin, there are a number of environment variables
that set/limit launch dimensions:
...
$ grep getenv libgomp/plugin/plugin-gcn.c | grep NUM
const char *x = secure_getenv ("GCN_NUM_TEAMS");
x = secure_getenv ("GCN_NUM_GANGS");
const char *z = secure_getenv ("GCN_NUM_THREADS");
z = secure_getenv ("GCN_NUM_WORKERS");
...
It would be nice to have similar ones for nvptx.
