Impacts and Recommendations

  • For applications that can use them, accelerators provide more compute capacity for a given investment
  • Accelerated work finishes faster or is accomplished with more fidelity
  • Money from a fixed investment spent on accelerators gives less compute capacity for unaccelerated applications
  • Development time is consumed porting or refactoring applications for acceleration, hampering development of new applications for other purposes
