I'm having problems on some of my servers that seem to be related to intelremotemond. When compiling C++ programs located in a shared NFS-mounted home directory, suddenly the machine seems to lock up. At the NFS server side, I can see a huge amount of open/getattr requests coming in that seem to be related to the intelremotemond process running on the client. This volume is apparently such that no other NFS commands are able to get through, hence the apparent lockup.
First I would like to thank you all for the awesome cilk plus tools you have open source in GCC and LLVM.
I am trying to study the runtime library and finding it a bit difficult to follow the execution in a sample application.
Are there any developer documents available? A wiki perhaps.
Specifically, I am trying to trace the execution path for cilk_spawn which is a key word. Any helpful links to get me started would be really great!
What I understood about steal-continuation is, that every idle thread does not actually steal work, but the continuation which generates a new working item.
Does that mean, that inter-spawn execution time is crucial? If 2 threads are idle at the same time, from what I understand only one can steal the continuation and create its working unit, the other thread stays idle during that time?!
As a debugging artefact, I had a global counter incremented on every function call of a function used within every working item.
In a previous post I discussed the Intel® Transactional Synchronization Extensions (Intel® TSX) technology released in the new generation of processors. I described the Intel® Threading Building Blocks (Intel® TBB) implementation of the HLE interface (
speculative_spin_mutex). Now we can talk about the implementation of
speculative_spin_rtw_mutex, a Preview Feature of TBB 4.2 Update 2.
I am big fan of Vtune, and it is the first time I use on MIC, and I have difficulty to extract result, especially Gflop/s and operational intensity. I follow the intel introduction of : http://software.intel.com/en-us/articles/best-know-method-estimating-flo....
for one thread, my command line is :
We are using intel's coverage tool for coverage tests and at the step where profmerge is called to generate DPI files from DYN, we get the following message:
Hellow my friends!
In MSVC2013 perfectly works for me this macro (which allow use enum class as flag enum and disallow convert to int):
On the same day that we announced the launch of our new IoT developer program at Mobile World Congress, we kicked off two sets of hackathons in Barcelona. With fifty developers each day,each with an Intel(r) Galileo board, a live USB, a wifi adapter, a set of cables and some sensors this was a pilot for the series of twenty IoT hackathons being planned for later in the year.
