Hello Friends ,
I ahve a Solaris code with processor_bind system call to bind LWPs to a
processor
The processor_bind() function binds the LWP (lightweight process) or set of
LWPs specified by idtype and id to the processor specified by processorid. If
obind is not NULL, this function also sets the processorid_t variable pointed
to by obind to the previous binding of one of the specified LWPs, or to
PBIND_NONE if the selected LWP was not bound.
I have checked the manuals and documents , but i found there is no equivalent
sys call in linux
The Linux system calls that are processor affinity based are
sched_setaffinity(2) and sched_getaffinity(2).
I would like to know is there any wrapper fun or workaround for processor_bind
in Linux
I am not quite sure if this is what you are looking for, but take a look at
pthread_setaffinity_np(3). This sets the affinity of a thread (as opposed to the
entire process), which is what a LWP would be called on linux, to a specific CPU.
cheers,
- steve
