Forum poll: Intel MKL and threading

Intel MKL users,

We would like to hear from you how you are using Intel MKL with threading. Do you use the parallel or sequential MKL? How do your multithreaded applications use MKL? We would appreciate you to complete a short survey. It takes no more than 5 minutes. Your feedback will help us to make Intel MKL a better product. Thanks!

Troubleshooting HOWTO: Bad hardware? MPSS? Configuration?

Are you having problems with your hardware (Cannot see your Intel(R) Xeon Phi(tm) coprocessor?  Sporadic accessibility?) or with the Intel(R) Manycore Platform Software Stack (Intel(R) MPSS) running reliably?

Attached to this post are PDF "flowcharts" that explain how you can troubleshoot the problem (note:  Both Linux and Windows flowcharts are available), and shows what information you will want to collect if you need to escalate your issue to your OEM provider or Intel.

基于 hadoop 文件系统以及 Hbase 的微博系统








     以基于Hbase的hadoop为数据库,实现用户发布微博和,关注用户及等功能,涉及到Hbase表结构设计,相应实现的Java API等一些内容。使用hbase作为微博系统的数据存储平台有如下好处:根据微博系统的特点,微博用户数量庞大,且关注和被关注数据严重不相等,这些特点刚好可以通过hbase分布式处理数据的一些特性得以满足,如果使用旧的关系数据库可能对一个单独的服务器要求非常之高。





What collateral/documentation do you want to see?

Do you have questions that you are not finding the answers for in our documentation?  Need more training, source code examples, on what specifically?   Help us understand what's missing so that we can make sure we develop documentation you care about (what is important, and what is nice to have)!   Thank you

FAQS: Compilers, Libraries, Performance, Profiling and Optimization.

In the period prior to the launch of Intel® Xeon Phi™ coprocessor, Intel collected questions from developers who had been involved in pilot testing. This document contains some of the most common questions asked. Additional information and Best-Known-Methods for the Intel Xeon Phi coprocessor can be found here.

Slides from May 4th Webinar on Cilk

Hi all,

We did a webinar this morning at 8am Pacific time on changes and new updates in Cilk in the Intel Parallel Composer beta. I am posting the slides here. Let me know if there's any interest to do another webinar on this around 5pm or so Pacific time - I want to see if there's anyone that couldn't attend due to the time that would have liked to attend. Thanks everyone, and I really enjoyed the questions in today's session.

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
