Mixing kernel space and userspace in a new kernel.
Von Jog L.0
Hello, I was thinking of creating an open source kernel (with block already written in the linux kernel obviously). Now I would like to hear from experts what are the dangers to run in ring0 if no users and no external connections are done. We are in a situation in which the processor is isolated from the whole world. No one can mess with it. all the processes running on top of it have to register and are created and compiled by root using a specific memory range. No process can be launched without the acceptation of root. No human accesses it. The code running inside is reviewed and we have facilities to be sure no other memory range than the one we expect each process to use can be used. That is for the -restrictive- context. Now, could we imagine it be possible for such a kernel to exist or are there some limitations that I don't predict ? The kernel is to be massively specialized, hence the "almost starting from scratch". Thanks for your insights, Jog
linking with two versions of mkl (multi threaded and single threaded) in one application
Von Michal K.3
Hi, Is it possible to use both the single threaded version of mkl library and the multi threaded version of mkl in one application? I need the single threaded version to use with PLASMA library, yet at some other part of my code, I need use mkl PARDISO, for which I need the multi threaded version. Any help will be greatly appreciated. Cheers Michal

Memory to CPU (mov) bandwidth limitations
Von albus d.3
(sorry for weak english I am not native english, Not sure if right forum, first time here - This is general about some hardware limits i do not understand technical reason and I would very like to know) We have now parallelised SIMD arithmetic (like 8 float mulls or divisions in one step) theoretical (but also nearly practical) arithmetical bandwidth per core is thus like 4GHz * 8 floats = about 30 GFLOPS per core or something like that But we still AFAIK have quite low RAM to CPU bandwidth at the level of read or write of 1 or 2 int of float per nanosecond, such ram-2-cpu bandwidth when i am testing it is like only 2 GLOP per second per core or something like that; (both those values are rough but this difference seem to be physical truth at least from my experience) I mean arithmetic can be paralelised (like 8-vectorised) but load/store movs are not - thus SIMD paralistation has obly a fraction of its potential power This is extremally crusial to increase this memory bandwith (muc...
speedup problem using openMP in intel fortran
Von bohluly2
Dear all, I have developed  a program and unfortunately I have speedup problem in it. My program is so big so I have tried to write a sample similar to my program, fortunately this simple program has a same problem with my program.  I need other experiences and your help if it is possible. Thanks, I am using VS2010 and Intel FORTRAN XE 2011 Program:     TYPE var         REAL(8),POINTER :: A, B, C      END TYPE var      REAL(8),POINTER :: A(:), B(:), C(:)      TYPE(var),POINTER  :: vars(:)        TYPE(var),POINTER :: varOMP            REAL*8  t1,t2 ,ai,bi,ci,di,ei,fi        INTEGER(4) c1,c2      INTEGER N, CHUNKSIZE, I, id, f , l      PARAMETER (N=200)      PARAMETER (CHUNKSIZE=10)            Allocate (A(N), B(N), C(N),vars(N)) !     initializations         DO I = 1, N          A(N)      =   I * 1.0          B(N)      =   A(N)          vars(I)%A =>  A(N)          vars(I)%B =>  B(N)          vars(I)%C =>  C(N)          vars(I)%A = 0.51          vars(I)%B...
How can I verify license key?
Von Aleksandr S.1
I have bought few Xeon Phi units. The reseller provided with keys for Intel Parallel Studio. I think they are 6 months demo. However I'd like to know for sure. Is there a way I can check the terms of these keys without activating them, directly with Intel?
Doubts before buy Intel Studio
Von Marcelo C.2
Hi All   I have some doubts regarding the Intel software studio for parallel arch and the Brazilian seller is not able to answer. I need to solve these doubts before buy the Studio for my company. Can somebody help me? 1- Currently we are using OpenMPI. Which advantages Intel MPI provides over OpenMPI? 2- OpenMPI error handling is not good. The MPI Lib from Intel is better for error handling and recovering? For example, if one rank in my mpi comm world dies how can I handle this using Intel lib? 3- Currently we use GCC. Intel compiler is better? We are running in a cluster with several nodes, with MPI doing the communication between the nodes.  Any other recommendations? We host our application at Amazon.  Thank you all in advance!
