Quoting Andrew Lentvorski <[EMAIL PROTECTED]>:
Ayup. And the tools vendors had *zero* incentive to port those tools
because suddenly they would be selling fewer licenses.
The EDA vendors *liked* the fact that it was called Slowaris.
True. The sadly ironic thing is that this really wasn't true. We
constantly heard from our engineers that if the stuff ran faster (and
this has become true as tools move over to linux on x86) they would
run more and more tests in the same time-frame to increase the
likelihood of catching any problems in the design. The vendors
wouldn't listen though.
As time has gone on, we haven't lowered our licenses much, if at all,
AFAIK. In fact we've mostly gone up in counts, though much of that is
also because we've increased the number of chips done over time.
Those same vendors had to be dragged kicking and screaming to x86 for
exactly the same reason.
Same thing is happening regarding making tools parallelized.
B) Linux is just a touch unstable when pushed hard
We've found that it handles the cpu load just fine, it's when it's run
into OOM situations too far and too fast that it falls over sometimes.
This seems to be alleviated with more swap space, which seems to
give the OS more time/room to react and recover. I've still seen
buggy apps knock over even a 128Gig machine though.. that was one
process. That was a seriously screwed up bug that just ate memory at
an insanely fast rate. I've seen similar bugs take down solaris hosts
too though.
If you do Solaris x86, suddenly these two things go away.
Which has such lackluster support thus far. Only a token few apps per
vendor thus far. With autofs5 now, the automounter on linux (which
was a real sore point there) is much more stable too. We're looking
to implement better limits on memory usage (trying to balance that
without effecting the ability for engineer apps to run ok most of the
time, because they tend to over-allocate horribly) will hopefully curb
most of the few problems we still see.
