Purpose: This a fix for bug #921 Description: On platforms where big test runs, it creates a set of "solid" 1GB files. Test will take forever (modi4) or will fail if quotas are exceeded. Solution: Default library behavior is to allocate dataset space earlier and to write fill values. I changed the test to use late space allocation and never write fill values. Platforms tested: True64 (PSC), modi4 (sequential and parallel), arabica with 64-bit option(test was skipped there). I also enabled szip and it passed :-) Misc. update:
