I published a paper this year that used it directly and even proposed a modification of it to model job time for a distributed execution environment with a centralized master governing scheduling, task serialization, etc.<p>When you talk scale-out of any large system, or manycore whatever, Amdahl&#x27;s law is absolutely fundamental, and when you hear someone say &quot;perfect horizontal scalability,&quot; Amdahl&#x27;s law governs when that will no longer be true.<p>People who do theory on distributed algorithms use it even if they don&#x27;t realize it.
