However, these transient resources must be evicted whenever latency-critical jobs require them again. Resource evictions often lead to cascading recomputations that substantially degrade job performance.&lt;/p&gt;
 
 &lt;p&gt;Pado[1] is an optimization technique that reduces the number of recomputations triggered by eviction of transient resources. Specifically, Pado uses a placement algorithm for selectively retaining intermediate results on reserved resources that are not evicted.&lt;/p&gt;
