220 High Performance Parallel I/O
18.3 Deployment, Usage, and Applications
GLEAN has been deployed on leadership computing systems at Argonne
for I/O acceleration, asynchronous data staging, and in situ visualization for
a number of diverse applications.
18.3.1 Checkpoint, Restart, and Analysis I/O for HACC
Cosmology
Next-generation sky surveys will map billions of galaxies to explore the
physics of the “Dark Universe.” Science requirements for these surveys de-
mand simulations at extreme scales; these will be delivered by the HACC
(Hybrid/Hardware Accelerated Cosmology Code) framework [5]. GLEAN’s
I/O performance was integrated and evaluated with the ...
