If I use fedora core 2 linux with SMP enabled, perl ithreads, and an
intel hyper-threaded server with ram in both banks, will a perl program
that uses ithreads to launch threads launch a thread on each
"processor"?
My motherboard used to show 2 cpus with my old linux distro (redhat
8?), but now it is not showing that with top.
I am trying to test a threaded application before going out and buying
a dual core server. I happen to have this hyper threaded machine and am
testing it out, but have been unable to confirm that the ithreads will
take advantage of hyper-threading or a dual core cpu.
Top does not show 2 cpu's, although I am sure the previous install of
redhat 8 or 9 that I had did reflect that. dmesg reports 2 cpu's.
Again, this is not a dual core or dual processor machine, it is an
intel hyper-threaded machine.
I am hoping that I can buy a dual core machine and use some form of
perl threads to improve performance of a custom application.
