Hi, The snapshot I CVS'd from the main line at 199902250900 UTC was the first since 19990127 that passed LAPACK's test suite on my i686-pc-linux-gnu (standard Red Hat 5.2 install). I used the following options to compile LAPACK: -g -O3 -funroll-loops -fomit-frame-pointer -fno-emulate-complex -malign-double Subsequently, I compiled and ran the test suite that goes with our numerical weather forecasting system; I compiled it with: -g -O2 -malign-double -ffast-math -fomit-frame-pointer -funroll-loops -Wall -Wsurprising -funix-intrinsics-hide Here are the timings [all times in seconds] with respect to the 19990127 snapshot (not encouraging): 19990127 19990225 0SUPOBS TOOK : 0.36000061035 0.32999992371 0DATACH TOOK : 148.4499969482 161.0299987793 0ANAEVA TOOK : 207.3500213623 291.8599853516 0GRPEVA TOOK : 1270.1099853516 1333.4100341797 0HUMSUP TOOK : 0.04992675781 0.05993652344 0DATACH TOOK : 45.6899414062 47.8800048828 0HUMEVA TOOK : 22.9599609375 32.1099853516 0GRPEVA TOOK : 31.1900634766 33.4400634766 PREPARATIONS TOOK 7.5400 7.1400 FORECAST TOOK 2445.3301 2509.9102 A further disturbing feature of the 19990225 snapshot is that the forecast part of the run took 54 Megabytes of RSS (as reported by ps and top) in stark contrast with 43 Megabytes of the 19990127 snapshot. Note that this is *Resident* size, so we're not talking about unused virtual memory here, but memory that's really *used*. Unfortunately, due to the long time between the two successful runs, it's hard to pinpoint the change that brought this about.
