The processor type of your Linux machine is x86_64 (aka AMD64). You'll
see this if you run "uname -a" on your Linux machine. Processor type
x86_64 is different from IA64 (Itanium) so you cannot install STAF Linux
for IA64 on a x86_64 machine (or vice versa). Itanium is a family of
64-bit Intel microprocessors that implement the Intel Itanium architecture
(formerly called IA-64). The Itanium processors are marketed for use in
enterprise servers and high-performance computing systems. You can
google for more information on the differences between these processor
types.
As far as performance, note that a simple request like STAF PING runs very
quickly on a machine running STAF for Linux AMD64. As you can see, 5000
local STAF PING requests can be run in 1 second.
[root@staf4g ~]# STAFLoop 10 local PING PING
Total loops: 10
Total time : 0.002
Avg. time : 0.000
Loops/sec : 5000
A PROCESS START request without the WAIT (which doesn't wait for the
command to complete) takes a little longer because it does more things but
can still submit 104 processes per second.
[root@staf4g ~]# STAFLoop 10 local PROCESS START SHELL COMMAND "ls /"
Total loops: 10
Total time : 0.096
Avg. time : 0.009
Loops/sec : 104.167
[root@staf4g ~]#
A PROCESS START WAIT request does even more things and takes longer
because it also has to wait for the command to complete.
[root@staf4g ~]# STAFLoop 10 local PROCESS START SHELL COMMAND "ls /"
RETURNSTDOUT RETURNSTDERR WAIT
Total loops: 10
Total time : 9.507
Avg. time : 0.950
Loops/sec : 1.05186
However, if you're only running commands that complete very quickly (like
"ls /") and only on your local Linux machine, then you could simply have a
shell command that runs your "ls /" command in a loop. The power of
running a process via STAF is more evident when you want to run processes
on remote machines, and/or on machines with different operating systems,
etc.

Subject: [staf-users] Why can't I use STAF341-linux-ia64.tar.gz on
my 64 bit intel cpu platform?
I tried staf on my 64 bit intel platform, but STAF341-linux-ia64.tar.gz
cannot execute, the prompt is:
/usr/local/staf/bin/STAFProc: /usr/local/staf/bin/STAFProc: cannot execute
binary file
STAF346-linux-amd64.tar.gz works fine on my intel 64bit platform, but it’
s issue is too slow to execute a command.
My test like this:
STAFLoop 10 local PROCESS START SHELL COMMAND "ls /" RETURNSTDOUT
STDERRTOSTDOUT WAIT
Total loops: 10
Total time : 9.480
Avg. time : 0.948
Loops/sec : 1.05485
Anyone has experience using staf on intel 64bit platform?
My cpu is :
Processors: 2 x Xeon 2.80GHz 800MHz FSB (HT enabled, 4 threads) -
Nocona E0, 64-bit, 90nm, L2: 1MB
thanks
