Now, There are three single channel images:
i don't now how to use "ippicopy_mod" functions to merge this three channels images to a RGB color image.
I saw a core dump due to such assertion failure. I start having this failure after integrate some third party libraries into my system. I suspect that third-party library is using some native thread. But still it does not make sense to crash tbb.
I'm using Tbb on fedora20 x86-64.
Assertion block->checkFreePrecond(object) failed on line 2396 of file ../../src/tbbmalloc/frontend.cpp
Detailed description: Possible double free or heap corruption.
My question is: what does this failure mean?
I have a problem considering adding tbb to system variables. I have succesfully installed Intel Parallel Studio and I wanted to compile the example applications with TBB. Therefore, I launched compilervars.sh script. After the launch, icc and cilk plus worked correctly (I do not change or quit the terminal in which the script was run)- however, when trying to launch tbb application, when running make in /tbb/examples/GettingStarte/sub_string_finder, the following error occurs:
fatal error: tbb/parallel_for.h: No such file or directory
I am trying to compile RedMD application with intel parallel studio 2013,
and i am getting following error!
hi,i am developing in network video project,but i find the cpu of ipp decoding and encoding h264 is so high ,more than 130 percent,i hope intel developer can give me some devices.THanks!!
with the makefile
I need to use cluster pardiso to solve a big double precision complex symmetric matrix. I set the iparm(40)=0, that means provide the matrix in usual centralized input format: the master MPI process stores all data from matrix A, with rank=0.
I use two compute nodes(each has 48gb ram). In the phase 33, solve and iterative refinement step, the master node (rank=0) uses 95% of the 48gb ram, the slave node (rank!=0) uses 73% of the 48gb ram.
I'm getting bad performance with MPI barriers in a microbenchmark on this system configuration:
My CPU is Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz.
I choose the Microarchitecture Analysis/Bandwidth and start the testing.
In the Bandwidth viewpoint panel, where is the average Bandwidth?
I put my screen shot in the attachment. I cannot find the bandwidth.
I also use the command line and the result is as follows. The bandwidth is zero. How come?
Elapsed Time: 70.813
CPU Time: 644.534
Average CPU Usage: 8.906
CPI Rate: 1.107
