Hi everyone,
This question is directed to Tomasz and to anyone who has experience
in doing large optimizations.
I am attempting to perform quite large optimizations with a large
amount of intraday data. I have a Windows XP OS, 1.2 GHz Athlon CPU
and 512MB SDRAM. The optimizations are of the order of 15,000
optimization steps over 50,000 intraday bars.
I would like to know what upgrades you believe will allow me to do
these optimizations faster. Which would in your experience enhance
performance more, an increase in RAM or CPU speed?
By monitoring CPU utilization and RAM utilization during these
optimizations, I noticed that Amibroker uses 100% of CPU ("CPU
USAGE" parameter in Windows Task Manager/Performance Tab) but only
about 60% of the RAM ("PF Usage" and "Commit charge" and "Physical
Memory available" in Windows Task Manager/Performance Tab). Those
are the figures I see but I will defer their interpretation to the
experts which I am not.
Any other suggestions that could enhance the time required to
perform these large optimizations? I know I could increase the step
size in the optimize statements but I would like to optimize on a
fine grain.
Any help is *much* appreciated. Thanks.
