Fixing COMPSs tracing error: PAPI_read failed for thread X evtset X (papi_hwc.c:*)

Question

我正在尝试运行启用跟踪系统 (extrae) 的 COMPS。我首先有一个安装问题，但我解决了它感谢这个问题：

但是，现在我面临一个新的 PAPI 问题。 COMPS 运行时间似乎已正确加载但 Extrae 报告此错误：

Extrae: Error! Hardware counter PAPI_L3_TCM (0x80000008) cannot be added in set 1 (thread 0)
Extrae: Error! Hardware counter PAPI_FP_INS (0x80000034) cannot be added in set 1 (thread 0)
Extrae: Error! Hardware counter PAPI_SR_INS (0x80000036) cannot be added in set 2 (thread 0)
Extrae: Error! Hardware counter PAPI_BR_UCN (0x8000002a) cannot be added in set 2 (thread 0)
Extrae: Error! Hardware counter PAPI_BR_CN  (0x8000002b) cannot be added in set 2 (thread 0)
Extrae: Error! Hardware counter PAPI_VEC_SP (0x80000069) cannot be added in set 2 (thread 0)
Extrae: Error! Hardware counter RESOURCE_STALLS (0x40000023) cannot be added in set 2 (thread 0)

尽管出现错误：

Extrae: Successfully initiated with 1 tasks and 1 threads

WARNING: IT Properties file is null. Setting default values

[   API]  -  Deploying COMPSs Runtime v1.4 (build 20160722-1520.r59)
[   API]  -  Starting COMPSs Runtime v1.4 (build 20160722-1520.r59)

但是在开始运行time 之后，我陷入了无限循环：

Extrae: PAPI_read failed for thread 1 evtset 2 (papi_hwc.c:669)
Extrae: PAPI_read failed for thread 0 evtset 1 (papi_hwc.c:669)

即使他们没有硬件，我也希望能够获得踪迹 PAPI 计数器。如何禁用它们或修复错误？

Answer 1

检查并禁用不可用的 PAPI 计数器

您的计算机中似乎没有可用的计数器。使用：

papi_avail -a

查看可用的 papi 计数器。编辑以下配置文件：/opt/COMPSs/Runtime/configuration/xml/tracing/*.xml 并从 <counters> 部分删除有问题的 PAPI 计数器。或者，您可以使用：

/opt/COMPSs/Dependencies/extrae/bin/papi_best_set COUNTER_NAME_#1, COUNTER_NAME_#2, COUNTER_NAME_#3, ...

查看 PAPI 计数器集是否存在某些不兼容问题。

禁用所有计数器

如果你想禁用所有这些，只需更改文件：

extrae_basic.xml
extrae_advanced.xml
extrae_task.xml

在 /opt/COMPSs/Runtime/configuration/xml/tracing/ 文件夹下并更改行：

<counters enabled="yes">

用于：

<counters enabled="no">
