"blocking mode"(阻塞模式)是一种编程模式,在这种模式下,当一个函数调用执行时,它会等待该函数的执行完成才返回结果。这意味着,在函数返回之前,程序的其他部分将暂停执行。阻塞模式通常用于同步操作,确保操作的顺序性和完整性。 2. 解释"polling"在这种模式下的工作原理 在阻塞模式下,"polling"(轮询)是一种不断...
As Frank said it was correct behavior of MCU which stuck in the while() line in polling mode. As you know there are three methods to transfer data: polling mode, interrupt mode and DMA mode, the while ((base->FIFOSTAT & USART_FIFOSTAT_RXNOTEMPTY_MASK) == 0U) belongs to polling mo...
Note: The Polling Interval for blocks is determined by the Event Monitor Polling Interval (Navigator pane > Configuration > Global Settings > Monitoring Service Settings > Advanced tab). SQL Server Name of the SQL Server hosting the SPID. Start Time Start time of the request. Duration The ...
Another possibility is that if you use polling mode to send and receive data, received data waiting for buffer maybe overwrited when you are sending data simultaneously. Because the depth of uart buffer is 1byte only. If you dont take it on time, it will lost.The way to av...
The impact that locking has on overall system performance can be monitored for blocks and locks by polling state data at given intervals (perhaps hourly) and capturing running statistics on the locks being held. Key information to capture is:...
my_net_init calls vio_blocking to put the socket in non-blocking mode. It ignores the return value from vio_blocking. my_real_read calls vio_blocking in a loop until it returns a value >= 0. Why doesn't my_net_init check the return value?

Normal functions usually execute in „blocking“ mode. A function usually returns after it's completed. A function that is able to execute in „non-blockingg“ mode will be executed in background without blocking the calling process. When the function completes it reports the result code and...
As you can see, the async backend indeed is a bit slower, butucxx-coreis consistent withucx_perftest. What versions of UCX and UCXX are you running? Could you also try withucxx-coreas above, and also separately with polling progress mode by settingUCXPY_PROGRESS_MODE=polling? luweizheng...
For ntp retry intervals, if there are better values, the cache interval in the NTP library should be set (defaulted) accordingly. I did some reading as well. The existing code is using the polling interval for the cache timeout. Once it gets a successful synchronization. Before that, it w...
