Question

有没有办法获取线程使用哪个内核？
例如

charge = stripe.Charge.get_or_create(
    amount = 900,
    application_fee = 100,
    currency = 'EUR', #TODO Marc source = token,
    stripe_account = "XYZ", #TODO Marc: Replace with organizer stripe account
)

new_charge_obj = Charge.objects.get_or_create(
    amount = charge.amount, #amount_refunded = charge.amount_refunded,
    charge_id = charge.id,
    livemode = charge.livemode,
    paid = charge.paid,
    refunded = charge.refunded,
    currency = charge.currency,
    failure_code = charge.failure_code,
    failure_message = charge.failure_message,
    fraud_details = charge.fraud_details,
    outcome = charge.outcome,
    status = charge.status,
    application_fee = charge.application_fee,
    captured = charge.captured,
    created = charge.created,
)

application_fee = stripe.ApplicationFee.retrieve(charge.application_fee)

Fee.objects.get_or_create(
    fee_id = application_fee.id,
    livemode = application_fee.livemode,
    currency = application_fee.currency,
    amount = application_fee.amount,
    charge = new_charge_obj,
)

Answer 1

C ++不提供实现此目的的功能或任何东西，因为该语言没有核心概念。

您可以通过系统调用运行Linux命令来检查以下内容：How can I see which CPU core a thread is running in?

Answer 2

如果您使用的是基于Linux的系统，则可以使用

sched_getcpu()

打印当前正在运行线程的CPU /内核编号

cout << "Thread running on Core " << sched_getcpu() <<endl
