Default multithreaded Synthesis and Place and route... Finally!

So I asked Altera when they would release a version of Quartus that
would support multi-threaded
place and route (this takes the most time on the designs I have worked
on)
I also asked them about the best (fastest) PC to run quartus on.
here's my questions followed by their answers.
-------------------------------------------------------------------------------------------------------------
Q:
at the end of year I am thinking of purchasing a new PC to do my
quartus
and EDA development on. I was wondering how the system requirements
will change with the release of vista, and what the ideal system
configuration for
running fast synthesis and place and route will be. Right now I am
having to wait between
15 minutes and two hours for various designs to compile. What system
components will most contribute to faster place and route and synthesis
(eg, more ram, more processors, faster ram, faster processors, 32 vs 64
bit
architecture?, any specific CPU more highly rated then others?)

A:
Altera does not have recommendations for CPUs/Mother Board. About the
choice for AMD or Intel processor, Altera does not have testcases to
show one way or another.

However, the compile time is mostly related to CPU speed and physical
memory size. For detailed information on memory requirements for
compilation targeting different device architectures, please refer to
the readme file by clicking Quartus II menu "Help -> Readme File".

If system memory is enough and Quartus II don't use hard disk as
virtual memory, you could try to upgrade your CPU speed for good
performance. However, if memory is not enough and hard disk virtual
memory is frequently used, the compilation time will increase more.
Therefore, I think we could firstly satisfy the physical memory
requirement of Quartus II compilation and then try to upgrade CPU
speed.

Multi processor system or multi-thread CPU will help you run other
applications at the same time as running the Quartus II compile, but
not necessarily will help with the compile time.

Quartus II can support 64 bit system. Generally, 64 bit Quartus II can
run faster than 32 bit if memory is adequately large (> 2G). However,
the performance upgrade is dependent on specific design project and we
can't provide detailed benchmark.

64-bit Quartus II version 6.0 can be installed in UNIX Workstations
(64-bit) (Solaris 8 and 9 only) or Linux Workstations (64-bit
AMD64/EM64T processors) (Red Hat Enterprise Linux 3.0/4.0 WS 64-bit for
AMD64/EM64T only).
-------------------------------------------------------------------------------------------------------------------
Q:
when will quartus be certified as being windows vista compatible, and
is a 64 bit windows/vista version planned?

secondly, with the rise of multicore and multiprocessor systems,
is work being done to parallelize the algorithms for synthesis and
place and
route in order to achieve speed benefits available through
multiprocessor systems as they become the norm in the PC market.

A:
I can't provide the exact schedule about Quartus II certification on
Windows Vista. It's also due to the maturity of the OS. However,
Altera software surely can support those operations systems if they are
popular.

Our roadmap for Quartus II software also includes multi thread or
multiprocessor system support. However, the release schedule is also
not determined by now. But it might be no later than the end of next
year. Thanks for your understanding.

Default Re: multithreaded Synthesis and Place and route... Finally!

I hoped, after reading the headline and the first sentence, that we get it
in 6.1... Look like we have to wait another year...

BTW: Regarding best CPU, I think that cache-size matters.
