Recently I meet the problem about how to configure the PMUs on Xeon Phi.
According to the document named "Intel® Xeon Phi™ Coprocessor (codename: Knights Corner) Performance Monitoring Units", it requires a configuration tool that has "Ring 0" access to kernel to configure the PMUs on Xeon Phi. VTune Amplifier is able to use these PMUs. However, as we want to have some fine-grained control on the codes that we want to profile, instead of using VTune directly, we would like to collect the PMU data with our own codes that only require "Ring 3" access.
My C++ code uses boost program_options in main() to read command line options. Later in the code I want to offload some computations on MIC.
Hello, I would like to compile MPSS on Scientific Linux 6.4 with MRG realtime (Kernel: 3.8.13-rt14.25.el6rt.x86_64). I tried to perform the instructions in the user guide in section 8.1 (http://registrationcenter.intel.com/irc_nas/3678/MPSS_Users_Guide.pdf) - However already the command: rpmbuild --rebuild \ mpss-modules-*.el6.src.rpm fails since there isn't any rpm in the src folder. I would assume that the instructions assume that I have already a MPSS installed.
I am running some multithreaded benchmark programs in Mic. Some programs don't scale beyond 32 threads and some beyond 64. I am trying to find out the reason why they are not scalable beyond certain number of threads. Definitely, the poor scaling is not a result of lack of computing resources (i,e we can run 244 hw threads without the problem of context switching).
I am trying to analyze this using Vtune but am still not sure how to study this issue.
Hi when I compile the code below I get warnings stating that data1 and data2 are not pointers to shared data, how can I remove these warnings (the code seems to run correctly).
Here is the source code
I have successfully installed MPSS 3.1 on CentOS 6.4, and everything is working fine with the stock kernel. I want to update the kernel, so I tried to rebuild ofed drivers with rpmbuild --rebuild ofed-driver-3.1-0.1.build0.fc13.src.rpm, and it's not working very well...
It fails with :
When I was using Internal bridge, sometimes (not sure how to recreate it) after reseting configuration of mic, I could NOT ping to the mic. On mic, from ifconfig command, there were a lot of dropped packages. reboot host node could resolve the issue. Any idea?
