Quartus doesn't work with Pentium Hypertheading!

Hi,
I have compiled with Quartus II 3.0 SP2s a project that fills a Cyclone C12
for 89%.
Quartus ends  the work later around 2.30 hours (Pentium 4 - 2.8Ghz).
If I try to compile the same project on a PC with processor Intel Pentium 4
with  Hypertheading technology, Quartus doesn't succeed in ending the
fitting, after 24 hours it is I still stop to the 80%.
In the same PC I succeed in quickly compiling less binding projects for the
fitting.

Is there someone other of you that has had the same problem?

Does a way exist for resolving this? I have tried to disable from the PC
BIOS, the Hypertheading, also this doesn't resolve the problem .

Hi Salvo,

The Quartus compiler applications do not make use of hyperthreading.
The compiler executables (quartus_map, quartus_fit, quartus_tan,
quartus_asm) are all single threaded applications. Based on our
experiments the absence or presence of hyperthreading has not had an
effect on Quartus compile times or results.

One way to eliminate if the problem you are seeing is being caused by
hyperthtrading is to run the compiler executables in command line
mode.

If I have a design called stor and the compiler action point name is
stor_flex10k the instructions to compile would be as follows from the
DOS command prompt:

quartus_map --import_settings_files=on --export_settings_files=off
stor -c stor_flex10k
quartus_fit --import_settings_files=off --export_settings_files=off
stor -c stor_flex10k
quartus_asm --import_settings_files=off --export_settings_files=off
stor -c stor_flex10k
quartus_tan --import_settings_files=off --export_settings_files=off
stor -c stor_flex10k --timing_analysis_only
quartus_eda --import_settings_files=off --export_settings_files=off
stor -c stor_flex10k

According to your description there were two different PC's used, one
a Pentium 4 2.8 Ghz and the other a Pentium 4 with hyperthtrading. Do
they have the same amount of RAM?

If you can do send me your machine specs and email me the qar file,
and the specs of the computer which is taking a long time to compile.
We would definitely like to investigate this further.

The hyper-threading "problem" is a red herring -- once you disable
hyper-threading in the BIOS, your machine will not use any hyper-threading
functionality and is in effect just a normal P4 processor.  There must be
some other problem with your compile -- see Subroto's post.
