Announcing the Intel® Parallel Studio XE 2016 Beta!

You may have received an email inviting you to the Intel® Parallel Studio XE 2016 Beta.  VTune Amplifier XE 2016 beta is part of the studio and adds OpenMP* parallelization inefficiency, imbalance and work sharing analysis to tune for more efficient use of parallel regions. It also now supports multi-rank analysis of MPI* compute nodes with or without OpenMP use.  Various ease-of-use enhancements include confidence indicators in General Exploration analysis results, "super tiny" bird's-eye view timeline, and "Platform" tab replacing "Tasks and Frames" tab.

spring3+hibernate4 service 中多线程事务异常及解决

初次使用spring3结合hibernate4做项目,迅速配置完成,测试,一切正常。

然而,当我在service层中另外开启一个线程,线程中的方法需要进行数据库操作,这个时候,悲催的抛出了异常:-org.hibernate.HibernateException: No Session found for current thread

当然,hibernate4的session是和当前线程绑定的,多线程中用sessionFactory.getCurrentSession()获取当前session自然不存在,不存在又不会自动创建,所以抛出了异常,无可厚非。

于是就想着怎么解决这个问题。

遍翻google、baidu,大部分都说如何如何配置,设置事务的传播属性propagation="REQUIRED",开启opensessioninview filter等等,无一对此问题有何解释(当然或许是我没翻到,有知道的麻烦告知)

在http://sishuok.com/forum/blogPost/list/2625.html#7523上看到相关配置,我就想作者这个项目该多线程运行正常吧,果断下载源码,修改测试,oh。。。跟我的错一模一样!

amplxe: Error: [Instrumentation Engine]: failed to create the detach process (clone failed)

running command

amplxe-cl -target-process dsd -collect hotspots
amplxe: Collection started. To stop the collection, either press CTRL-C or enter from another console window: amplxe-cl -r /r000hs -command stop.

then stopped but got the following error:

^Camplxe: Error: [Instrumentation Engine]: failed to create the detach process (clone failed)
amplxe: Collection detached.
amplxe: Collection failed.
amplxe: Internal Error

Could anyone help? Thanks

Program is faster when launched from VTune

Hi,

I've noticed that if I time my program launched from the command line, it is slower than when I launch it from VTune (~25sec vs ~18sec). I've already checked that I'm running the same binary with the same options. Also, when I run it from the command line I run it 5 times consecutively.

I've noticed that, when launched from command line, the CPU stays in "slow" mode (at 1600MHz measured by CPUz), but when launched from VTune the CPU enters "turbo mode" (goes up to 2400MHz measured by CPUz).

Advanced Hotspot analysis problem

I’m trying to analyse an OpenCL program with VTune Amplifier XE 2015 (update 4) using VS2010 and VS2013 on Windows 7 enterprise.

Under "Algorithm Analysis", I choose 'Advanced Hotspots", and then select, from the "Analyze Processor Graphics hardware events" dropdown, either "Overview" or "Compute Basic", I get the banner message:

 “Processor Graphics analysis is only available on systems with Intel HD graphics and Intel Graphics Driver installed.
