3/31 I'm running irix on a two processor machine. Is there a way
to lock a certain process down on one processor
(in the sense that process A can only run on processor 1 and
not on processor 0) ? Lets assume I have root.
\_ I'm just surprised that a berkeley student managed to get his
hands on a dual processor SGI. Those things are freaking expensive.
\_ Actually, I dont. I'm running simos (processor simulator)
in a dual processor mode while running irix5.3 on it.
\_ Dual processor Octanes only go for about $30,000 . It's
not inconceivable that he has a job or is working on
a project that bought one. Of course, we now know this is
not the case. --dim
\_ For $30,000 you could have gotten several of their new
540 and 320 series workstations. From what an SGI
engineer told me those machines have a considerable
amount more bus bandwidth but cost much less than their
O2's. And the best part is that the latest linux kernels
support them.
\_ or spend $10,000 on a dual (or quad?) pentium,
and run solaris on it.
\_ Why would anyone spend $10,000 on crap from Intel.
\_ Because I'm not a religious fanatic?
I just picked up a dual 604e 200 card ($149) and
the combined total of 802 BogoMIPS puts even dual
333 Pentium II (~$1000) with 599 BogoMIPS to shame.
x86 is a dead arch., and with the latest offerings
it is starting to stink (like putrid meat).
If you need SMP for business reasons go with
UltraSPARC II.
\_ uh, "bogomips" says absolutely nothing about how
fast the machine is. -tom
\_ if it's pure integer, ultrasparc is a total waste,
price-wise. Now tell me the specrate on your
dual 604e system. Then give price of *system*.
\_ the NT machines have "0 cost" texture mapping but
don't claim to beat the polygon rates of our octane or
origin+IR for realtime VR (cave). my $5000 dual
450 MHz PII, ultra-wide SCSI, 256MB desktop w/ linux
runs large autoconf+cc loads comparably to the octane,
and snappier X console than any of our ultrasparcs.
\_ % runon n cmd
runs cmd on processor n
% man sysmp
tells you how to lock a process down to one processor,
and how to restrict a processor to only certain processes. |
