Trying to make use of the MPI persistent communication primitives in our application, I'm ending up with the following sequence of events:
The Intel® Math Kernel Library (Intel® MKL), the high performance math library for x86 and x86-64, is available for free for everyone (
Dear Intel Staff,
I would like to pre-allocate a number of buffers for later data transfers from CPU to MIC, using explicit offloading in C++.
I have an intel i7-4770 cpu.
Running my CFD simulation code using 1 - 3procs works well. However, when using >=4 procs, I almost always get 2 lines of the error:
I am having problem destroying Intel MPI program, the original problem is described at this thread.
MIC requires strict 64Byte data alignment to utilize vpu, but why? I found Sparc also have such an requirement. But other multi-core CPU can handle unaligned data.
I'm attempting to run a simple offload example:
