But Amine, why do you want to satisfy many requirements

Hello,

Question:

But Amine, why do you want to satisfy many requirements for your FIFO
queue, such
as minimizing efficiently the cache-coherence traffic,
and the FIFO fairness, and also the energy efficiency ? why
the energy efficiency ?


answer:

Energy efficieny is also important, cause we must not think just
for today , we must think for the future when there will be many
more cores, this requirement of energy efficiency will become much more
important, so as i told you it's sad that those waitfree and lockfree
FIFO queue algorithms must use spin-wait when there no item in the queue
and the threads must wait for new items etc. so as i told you, to
satisfy the requirement of energy efficiency we must use my FIFO fair
SemaCondvar or FIFO fair Semaphores inside the FIFO queue, but since my
SemaCondvar
and Smeaphores are slow , this will slow the FIFO queue, and that's sad.



Thank you,
Amine Moulay Ramdne.
