Test of acceleration due to SKIR<br />
Offload CalculateForces kernel to SKIR<br />
Shows mean time per simulation iteration<br />
ref = ord<strong>in</strong>ary <strong>JavaScript</strong><br />
sluice = sluice implementation<br />
skir = sluice implementation + SKIR offload<br />

Test of data parallelism<br />
Offload CalculateForces kernel as a data<br />
parallel kernel, use SKIR kernel fission<br />
Shows speedup vs. s<strong>in</strong>gle thread<br />
● Use 2, 4 or 8 SKIR threads (4 cores / 8<br />
hardware threads)<br />
●<br />
<strong>JavaScript</strong> also uses one thread
