Hi All,
I’m trying to debug a code and using printf in the kernel code for the same. In my kernel code I have a statement like this
printf(“Entering thread Id is %d\n”, threadIdx.x);
When I execute the kernel it doesn’t print the 0 thread id. Again when I change the printf to this statement
if(threadIdx.x == 0)
printf(“Entering thread Id is %d\n”, threadIdx.x);
now it prints that 0 thread is entering.
Does this mean printf doesn’t print all the statements…?
or
When I’m including the if statement my code execution flow is changing and it is printing…?
I doubt the latter case but are there chances of it…?
Regards,
