Which is what I just wrote before, i.e. that change from asm to C was done for maintainability.Last edited by salass00 on 25-Oct-2013 at 08:02 AM.

Yes , Salasso0 inadvertantly answered the reverse of your question, explaining the change from asm to C rather than why asm originally.
The most usual reason for asm is speed, perhaps occasionally size, but I don't honestly see the point in speculating over a such a design change. The important part is that the scheduler now deals with multiple cores according to the blog. _________________ BroadBlues On Blues BroadBlues On Amiga Walker Broad |

There was a mention of it in March: http://blog.hyperion-entertainment.biz/?tag=execsg
ExecSG is a mix of PPC assembly and C, the task scheduler has now been rewritten in C as well as turned into a plugin-system where you can make your own. Methinks that's a cool idea. Some like fairness ("nice" in unix terms), others (mostly me, I guess) absolutely abhor it and insist on a strict round-robin 
load-balancing must surely mean SMP, but it's hard to say what it does without more info. Like, which load (memory, cache, ALU) etc.
Cache wise it's advantageous to pin a thread to always run on the same core. resource-wise it might not be, though. _________________ This weeks pet peeve: Using "voltage" instead of "potential", which leads to inventing new words like "amperage" instead of "current" (I, measured in A) or possible "charge" (amperehours, Ah or Coulomb, C). Sometimes I don't even know what people mean. |

True, though it might result in those few programs which really need the heavy processor being (re)written in a multithreaded way, therefore individual threads could remain on the same core with the application still benefitting from SMP._________________ RobTheNerd.com | InstallerGen | SMBMounter | Atoms-X |

Thats all i suggested myself. Originally the sheduler was written in ppc asm for speed and now it has been rewritten to c for maintabolity and expandability in order to implement smp, or whatever ssolie calls it ;) Last edited by wawa on 25-Oct-2013 at 12:23 PM.

Maybe it's that, or maybe it's your general policy for sticking in a put-down or negative remark as often as you can... Far too often for someone who "doesn't care so much" if you ask me... Last edited by Daedalus on 25-Oct-2013 at 06:21 PM.

in this particular case i have not cared much, till i have been linked to the above discussion on amigans. you can check if i had made any post about this matter prior to today anywhere, except perhaps like "ah, lets dont care".
edit out: blaming the messanger as usual.Last edited by wawa on 25-Oct-2013 at 07:33 PM. Last edited by wawa on 25-Oct-2013 at 06:57 PM.

You are not mentioned on that thread any where, unless you go by another nic? Did you just admit to being "takemehomegrandma" ? (forgive me if that's common knowledge I would never have made the connection).
Or did you link to the wrong thread maybe?
/me confused

I see "AmigaOne A5000" name will upset friends of AmigaOS like you and takemehomegrandma. Not bad. 
However, my vote is for A1-Q5020 (or A1-X5020). |

Voted for X2000 series, as that is how I see those boards: enhancement of experience built on X1000, mostly same board features as Nemo with exception of DDR3 and Freescale non Altivec CPU (but actually Nemos weak side is relatively weak CPU so its good experience learning).
As far as I understand Cyrus is even smaller then Nemo. _________________ OS 3.x AROS and MOS supporter, fi di good, nothing fi di unprofessionalism. Learn it harder way! SinclairQL and WII U lover :D YT http://www.youtube.com/user/rasvoja |

| Info taken from main news.
Gallium3D: . Since the new API will allegedly support older PowerPC hardware targeted at legacy Amiga models.
Are all classic users GFX card(s) supported? As I did read somewhere in a thread Gallium is not for very low end GFX cards am I now understanding Gallium will now support Bvision & Voodoo and GFX card(s) above on classic system? _________________ The Machine: Bride Of The Pin•Bot by Williams Electronics |

No. I think SSolie meant computers with slow CPUs. I don´t know, if PCI-to-PCIe adapters can be used in PCI expansion like Mediator on classics. |
