修复COMPSs跟踪错误:线程X( PAPI_read )失败

Question

我试图运行COMPSs与追踪系统(外星)激活。我最初有一个安装问题，但是我解决了这个问题，谢谢这个问题：

cannot open shared object file when running (py)COMPSs with tracing?

然而，现在我正面临一个新的帕皮问题。COMPSs运行时似乎已正确加载，但Extrae报告了以下错误：

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)

尽管我犯了错误：

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)

但是在启动运行时之后，我在一个无限循环中得到了这样的结果：

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)

我希望能够得到跟踪，即使他们没有硬件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

在您的机器中似乎没有可用的计数器。使用：

papi_avail -a

查看可用的爸爸计数器。编辑：/opt/COMPSs/Runtime/configuration/xml/tracing/*.xml下的配置文件，并从<counters>部分删除违规的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计数器集中是否存在某些不兼容。

禁用所有计数器

如果您想禁用所有这些文件，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">

适用于：

<counters enabled="no">
