I am wondering how/whether the number of threads affect the numerical results computed by MKL.

Section 8.1 of the MKL (version 10.1) user's guide states that

"With a given Intel MKL version, the outputs will be bit-for-bit identical provided all the following conditions are met:
• the outputs are obtained on the same platform;
• the inputs are bit-for-bit identical;
• the input arrays are aligned identically at 16-byte boundaries."

Does this really mean, that I can link the threaded MKL libraries and vary the value of OMP_NUM_THREADS and still expect bit-for-bit identical results given the above conditions are met?

Thanks for you comments! ]]> http://software.intel.com/en-us/forums/intel-math-kernel-library/topic/70105/ Tue, 24 Nov 2009 05:48:08 -0800 http://software.intel.com/en-us/forums/intel-math-kernel-library/topic/70105/ ISN General gamma function? http://software.intel.com/en-us/forums/intel-math-kernel-library/topic/70067/ Tue, 24 Nov 2009 02:45:07 -0800 http://software.intel.com/en-us/forums/intel-math-kernel-library/topic/70067/ ISN General Implicite multithreading ???
Two question about the MKL functions from my recent test program:

1. Does the mkl function use multiple cores via multithreading implicitely? I have timing of "sgemv" on a 8-core cpu. My testing result shows it's surprisingly fast! Only two times of the GPU blas function: "cublasSgemv" for large size matrices (10000 by 10000).

2. If I repeat calling "sgemv" it becomes faster and faster. Finally for 2000 by 2000 matrix, it is as fast as gpu version "cublasSgemv". But initially, it is much slower than gpu version (about 30 times).  the Code is like:

for (int i=0; i<100; i++)
{
// start timing
sgemv(...)
//end timing
}
my timing unit is small enough to distinguish 0.0001 ms.

could any experts explain the reason bebind it?

many thanks in advance!

LINKING: 
LIBS=-L/$(FEASTROOT)/lib/x64/ -lfeast $(MKLPATH)/libmkl_solver_lp64.a -Wl,--start-group $(MKLPATH)/libmkl_intel_lp64.a $(MKLPATH)/libmkl_intel_thread.a $(MKLPATH)/libmkl_core.a -Wl,--end-group -lpthread

I discovered a bug so mysterious that I was only able to identify its cause/resolution by a mere chance (or luck).
I was trying to run my code on a cluster, but within a singe node only, i.e. with OpenMP only.

Very soon I discovered that the code that runs fine on any regular linux workstation, on the cluster produces an incorrect result after the third iteration. Two previous iterations gave identical to workstations (correct) results.

I figured out the reason was in dynamic MKL libraries that somehow were used, even though the code was compiled with -static and linked with static libraries (see above).
A logical explanation would be that the error arises due to an interference between outdated dynamic libraries installed on the cluster and the newer MKL with which the code was linked.
I tried to compile the code (obviously I compile on MY machine, not the cluster) with dynamic libraries:
LIBS=-L/$(FEASTROOT)/lib/x64/ -lfeast $(MKLPATH)/libmkl_solver_lp64.a -Wl,--start-group -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -Wl,--end-group -lpthread

Since the executable now required dynamic libraries I had to copy them, one by one, to the cluster too (and, of course, LD_LIBRARY_PATH had to be set).
I had to copy the following .so one by one, until the code was able to launch:
1. libmkl_intel_lp64.so
2. libmkl_intel_thread.so
3. libmkl_core.so
4. libmkl_lapack.so
5. libiomp5.so

So far so good. Then, before the first iteration was over, the code again stopped and complained that

MKL FATAL ERROR: Cannot load neither libmkl_mc.so nor libmkl_def.so

which was not unexpected.
Now the mysterious part. I first copied libmkl_mc.so to the cluster. The code ran fine, but on the third iteration produced an incorrect result (as before).
Then, I don't know why, I decided to try to delete libmkl_mc.so and copy libmkl_def.so instead. The code now runs fine producing correct results!!

What is going on here? What are these dynamic libraries mkl_mc and mkl_def, why are they "interchangeable", and why only one (mkl_def) works fine?!

P.S. I since read that mkl_mc is the kernel for core duo and mkl_def is the default kernel. The cluster has Xeon(R) CPU X5355. Should I use mkl_p4n and if so - how? 

P.P.S. Now when I understand mkl_mc vs mkl_def issue, my main question is:
Why the code with static linking (eventually) fails, and the one with dynamic linking works on the cluster?
Why it happens only on a cluster (on any workstation both dynamic and static versions work identically)?

IFC version: 11.1.051
Platforms: linux x64, win7 x64

The compiler complains about MKL_GET_MAX_THREADS() when being called
MKL_MT=MKL_GET_MAX_THREADS()
("This name does not have a type, and must have an explicit type. [MKL_GET_MAX_THREADS]"

In the same code the subroutines, e.g. call MKL_SET_NUM_THREADS(N), are being executed just fine.

What's the proper F95 interface to MKL_GET_MAX_THREADS() function? Is there a way not to provide the include path (which is an artifact of F77)?
 I just think it would be much more convenient to make a module like omp_lib for MKL functions.
Thanks.

I am using MKL's "zgetri" function in C. Since I am porting our code to use MKL, it is not possible to change our data type from "complex<double>" to MKL's "Complex16" everywhere in the code. The MKL's User Guide gives a solution to this to add these lines:

#define MKL_Complex16 std::complex<double>
#include "mkl.h"

I would like to know will it work correctly if I use my old matrices which use complex<double>, of course if I use a column major matrix for compatibility sake with Fortran?

I used this method and when I compile the code I get this error:

../include/mkl_types.h(43): error: expected a ";"
} MKL_Complex16;
^

../include/mkl_types.h(43): warning #64: declaration does not declare anything
} MKL_Complex16;

why this happens? This is the solution from MKL's user guide. Thanks for you help.

D.

There seems to be a bug somewhere in the interaction between Java and MKL. Hopefully someone has seen this, or can reproduce the bug.

 

To create the JVM crash, simply modify the source code for the dgemm.java example supplied with the 10.1 MKL to include these lines:

int sz = 4000;
double[] x = new double[sz*sz];
for(int r=0;r<sz*sz;r++) x[r] = Math.random();
double[] y = new double[sz*sz];
CBLAS.dgemm(Order,TransA,TransB,sz,sz,sz,alpha,x,sz,x,sz,beta,y,sz);
double[] z = new double[sz*sz];
for(int r=0;r<sz*sz;r++) z[r] = Math.random();
CBLAS.dgemm(Order,TransA,TransB,sz,sz,sz,alpha,z,sz,z,sz,beta,y,sz);

 

Rebuild the examples, and run with increased memory limits (-Xms1024m -Xmx4096m), and the JVM crashes in the calculation of the second matrix multiplcation. I can generate the same problem with other BLAS routines, and with LAPACK routines too. I have run this with different jdk1.6 releases, and on Red Hat and Ubuntu intel64 systems, and with MKL 10.0,  with the same results.

Here is the log from the JVM crash:
