Supertask
（重定向自Supertasks）
In philosophy, a supertask is a countably infinite sequence of operations that occur sequentially within a finite interval of time. Supertasks are called "hypertasks" when the number of operations becomes uncountably infinite. Supertasks are called "equisupertasks" when each individual task must be completed in the same amount of time. The term supertask was coined by the philosopher James F. Thomson, who devised Thomson's lamp. The term hypertask derives from Clark and Read in their paper of that name. The term equisupertask derives from a paper by Jeremy Gwiazda.
