Hi
I have some problem need to figure out
Before I descript my questions, I have to explain why I use COINS
Because I want turn normal C source code into a parallel C program And it
can execute on embedded system.
so I need auto loop-detection and optimization mechanism.
Therefore the first question is how to use it? I follow the command on the
web site
"java coins.driver.Driver -coins:parallelDoAll=OpenMP -coins:target=x86
test2.c"
No problem with this command, I got "foo-loop.c" and a binary file "a.out"
But when I executed a.out, it's not run like parallel.what can I do next
step?
What wrong with it?
Second question, I used cgParallel but I got wrong message like below:
[hpc ＠ hpc ]$ java coins.driver.Driver -coins:cgParallel -coins:target=x86
test2.c

/tmp/COINS8349653162205958917.tmp: In function `main':

collect2: ld return 1
what's happen?
Thank read my question with patience.
