But why would you want to create that many vmas? If you're going to call sys_numa_mbind() at object level you're doing it wrong. Typical usage would be to call it on the chunks your allocator asks from the system. Depending on how your application decomposes this is per thread or per thread-pool. But again, who is writing such large threaded apps. The shared address space thing is cute, but the shared address space thing is also the bottleneck. Sharing mmap_sem et al across the entire machine has been enough reason not to use threads for plenty people. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
