我为 MIC 编译并安装了最新的 PAPI 5.4.0.0。我的配置选项是：

CC=icc CXX=icpc ./configure --with-mic --host=x86_64-k1om-linux --with-arch=k1om --with-ffsll --with-walltimer=cycle --with-tls=__thread --with-virtualtimer=clock_thread_cputime_id

问题是 PAPI_add_event 在我自己的程序和测试程序中总是失败。报告的错误是“无效参数”。知道为什么吗？我尝试重新配置并重新安装，但问题仍然存在。

[root@mic2 bin]# ./papi_cost
Cost of execution for PAPI start/stop, read and accum.
This test takes a while. Please be patient...
cost.c                                       FAILED
Line # 231
Error in PAPI_add_event: Invalid argument

这些是“api_component_avail”显示的结果。对我来说这看起来很正常。它也与此线程匹配：https ://software.intel.com/en-us/forums/topic/530598

我将 PAPI 的版本从最新的 5.4.0 降低到以前的 5.3.2，问题就消失了。因此，我相信这是当前版本的错误。
