Benchmark and port RAXML
code to Dash.
Completed
porting and
benchmarking of
code on Dash.
This includes
testing on the
vSMP node.

The goal is to evaluate the
potential of using flash
storage to accelerate
commercial finite element
codes like Abaqus,
NASTRAN, ANSYS, etc
which have large I/O
requirements during the runs.
Wide applicability since there
is a large user base for such
codes.

(S2A1, S4B)
using flash
storage for I/O.
Preliminary
results show
~50%
improvement for
8 core runs.

Oregon
The project aims to analyze
profiling data from runs on
Kraken (up to 64k cores).
These are very large files that
need to be read into memory
(merged) so that users can
analyze the performance data
and visually examine the
results. The vSMP node is
attractive since it has a lot of
aggregated memory. PIs’
group develops the widely
used TAU profiling and
tracing toolkit for
