[alcf-discuss] Labeling stdout, stderr with rank?

[Jeff Hammond]

I'm sorry I cannot answer the question directly, but is it not
reasonable to label fprintf statements directly?

printf("hello world\n");

becomes

printf("%d: hello world\n",DCMF_Messager_rank());

I imagine you can do this with the preprocessor or a remapping of
printf itself, although the latter may involve some fun-and-games with
symbol redefinition at link time.

Best,

Jeff
