Hi Meng-Ju thanks for your answer, is that all?, it's very easy, when I saw
the example I thought that if I put 8, 16 or whatever in the
options.num_cpus what I'm doing is adding more cpus to the system not
cores., so just changing that variable do I change the cores?.
Now I got another question. In your code you assign at the end a process to
each core, and you initialize the process variable with files called
Mybench.gobmk[i], can you post one of those files, I've try to create my own
test file but when I try to simulate it in ALPHA_SE mode I get the following
output:
warn: Unknown architecture: 3
fatal: Object file is a dynamic executable however only static executables
are supported!
Please recompile your executable as a static binary and try again.
I suppose because I'm compiling incorrectly the file, to compile the file I
do this gcc -static MyTest.c -o MyTest, anybody know how can I compile a
test file for the ALPHA architecture. Thanks.
Do you now where can I find how to assign programs to each core, I know h
