I am trying to re-implement a linear control problem in sdpa format (I almost did it six years ago, now that I have time I analyze that again but some files were lost) The problem min trace of a symmetric psd matrix defined by 4 diagonal from 10 coefficients: ai Subject to: (B(ai), M’; M , an) >= 0 (must e Psd) I struggle to find the appropriate form. Dual form would be good for me as I can define ne matrix -(A(y) - C) <= 0 but I remember that I had used block matrices for defining positiveness of some ai. If primal form must be used I don’t get how to write the correspondance of the matrix X to the vars of my problem I join the publication Thanks Frédéric Peugny 06 50 32 92 74 Résidence les Berges du Midi, Bat.

Dear Yuri, Thank you very much for your email. I have uploaded a new version 7.3.17 to sourceforge. I think the file will soon appear at https://sourceforge.net/projects/sdpa/files/sdpa/ The mumps version is modified to 5.5.1. Thank you very much again.

Hello, I recently tried to install SDP-GMP on my Ubuntu based distribution. Unfortunately, the installation always fails, when I execute the make command. The error message tells me that the "storage size of 'TZ' isn't known". I found a discussion on the error in your forum https://sourceforge.net/p/sdpa/discussion/1393613/thread/260c6508/?limit=25#5af9 The suggested fix doesn't work. After editing the code, the make, make check or make install command still fails. Do you have any ideas how I can fix the problem? Thank you for your help! Best, Andreas |

Dear Xuan Zijie,
Thank you very much for your interest in SDPA.
The Ubuntu package does not include the compiled binary of mexsdpa, since
Matlab is not a free software.
(The binary files in the Ubuntu package are for Octave.)
The users need to compile the binary by themselves.
Could you please try the following commands?
sudo apt install sdpam
cp -r /usr/share/sdpa/mex ~/sdpamex
cd ~/sdpamex
make MAKE_INCLUDE_DIR=/usr/share/sdpa
Then, in Matlab, please add the path as follows:
>> addpath('~/sdpamex')
I have checked the above things in Debian,
so the directory names like '/usr/share/sdpa/mex' can be different in
Ubuntu.
Sincerely,
Makoto Yamashita

Dear Golnoosh Dehghanpoor,
Thank you very much for you interest on SDPARA.
Unfortunately, SDPARA does not have the MATLAB interface.
Please use intermediate files.
The following commands in the SDPA mex files might be useful.
(1) gensdpafile.m
>> gensdpafile('myexample.dat-s',mDIM,nBLOCK,bLOCKsTRUCT,c,F);
will output the SDPA-M structure into 'myexample.dat-s'.
(2) read_output.m
>> [objVal,x,X,Y,INFO] =
read_output('example1.result',mDIM,nBLOCK,bLOCKsTRUCT);
will read the result file generated by SDPA or SDPARA.
If you solve 'example1.dat-s' by
$ ./sdpa example1.dat-s example1.result
then this result can be read by
>> [mDIM,nBLOCK,bLOCKsTRUCT,c,F] = read_data('example1.dat-s');
>> [objVal,x,X,Y,INFO] =
read_output('example1.result',mDIM,nBLOCK,bLOCKsTRUCT);
Best regards,
Makoto Yamashita

Hi, I downloaded the sdpa/sdpa-7.3.9-windows.zip. There is an application in it and I want to run it on windows. I used the CMD and the command "sdpa ./example1.dat-s ./param.sdpa" to run it on windows. But the program terminated with an fatal error. I would like to know how to use it on windows or how can I get a excutable program from the source code. Thank you very much. |

Dear Micah Fry,
Thank you very much for your interest on SDPA.
On Cent OS, OpenBLAS sometimes failed to include the two functions.
To include the two functions explicitly, could you edit Makefile of 'mex'
subdirectory?
(LINE 94, from)
ALL_LIBS = ${SDPA_LIB} ${MUMPS_LIBS} ${LAPACK_LIBS} ${BLAS_LIBS}
${PTHREAD_LIBS} ${FCLIBS}
(LINE 94, to)
ALL_LIBS = ${SDPA_LIB} ${MUMPS_LIBS} ${LAPACK_LIBS}
/home/mfry90/sdpa/OpenBLAS/interface/dsyr.o
/home/mfry90/sdpa/OpenBLAS/interface/idamax.o ${BLAS_LIBS} ${PTHREAD_LIBS}
${FCLIBS}
then, try to compile again.
I hope this will work on your environment.
Thanks,
Makoto Yamashita

I am trying to install SDPA-M on a computing server with a CentOS shell. During the config for SDPA, it reported the MUMPS link failed, and the function dmumps was compiled, but failed (I've attached an image of the report, "config.PNG"). I still made and installed SDPA, and ran the example1 test. Everything seemed to run fine. When I ran "make" in sdpa/share/sdpa/mex, it failed because of undefined references in the dmumps_ functions (I've attached an image of the report, "mex.PNG"). I've also attached the config.log file.

Dear all, I am currently trying to use SDPA in order to solve some SDP as a subproblem (to improve bounds I obtain during a branch-and-bound search using some other optimization methods). This search usually processes in parallel; therefore, I want to create several independent instances of SDPA and call the solve(), input...() and other methods on them concurrently. Currently, I am running into problems with that - I get barely reproducible errors (segmentation faults, wrong answers, aborts with cryptic error messages, double frees, deadlocks ...). These errors disappear if I restrict the search procedure to a single thread. Is this type of usage supported by SDPA? If so, how can I do this? Moreover, in GDB, it looks like SDPA or some library called by SDPA spawns threads each time the solve() method is called. Is there any way to prevent this from happening, i.e. to make SDPA (including all subroutines) do all the work in the thread calling solve()? I am using the callable library from C++ code on a Gentoo linux system. My application and SDPA are both statically linked against my system dmumps, mumps_common, blas (reference implementation), cblas (GNU scientific library implementation), lapack (reference implementation), pord and mpiseq. Kind regards, Phillip Keldenich PS: Is there any way to get rid of noise like "Entering DMUMPS driver with JOB, N, NZ = -2 0 0" printed to stdout? |

Dear Golnoosh We have developed SDPARA 7.5.0-G and 7.6.0-G, however, which are not released yet. They utilized GPUs and achieved high performance compared with previous versions of SDPARA. We must do an operation confirmation on various systems with GPUs and we don't finish it yet.

Dear Dr. Golnoosh Dehghanpoor, Thank you very much for using SDPA. The SDPA format has two types, sparse format and dense format. The nnn.txt file is written in the sparse format, but its extension is txt, not dat-s (dat-s is the default extension of the SDPA sparse format). To indicate explicitly that the input file is written in the sparse format, could you please try the following command? $ sdpa -ds nnn.txt -o nnout.txt Or, please rename nnn.txt to nnn.dat-s. In this case, $ sdpa nnn.dat-s nnout.txt is available.

Dear Dr. Chao Duan, Thank you very much for trying SDPA-M. I have checked the code of SDPA, and as you wrote, SDPA stops with "dfeas" only when the dual problem reaches the feasibility and the iteration number exceeds maxIteration. Since the default number of maxIteration is 100, I agree that the termination with only nine iterations and "dfeas" is a strange result. If possible, could you send me the input data? I will investigate the situation more closely.

The manual say "dfeas" means the dual problem got feasible but the iteration has exceeded the maxIteration. But clearly it is not the case here. So what's the real reason for such early termination ?

Dear Professor Sriram Sankaranarayanan,
Thank you very much for your interest on SDPA-GMP.
The error was caused by log(0).
So, could you modify a source file 'sdpa_io.cpp' as follow?
Before: Line 1315
mpf_class digits = -mpf_approx_log10(abs(PDgap/mean));
After : Line 1315
mpf_class digits = 0.0;
if (PDgap != 0.0 && mean != 0.0) {
digits = -mpf_approx_log10(abs(PDgap/mean));
}
Then, please compile again by
$ make
If the error still occurs, please feel free to ask again.
Sincerely,
Makoto Yamashita

Dear all,
I am a computer scientist investigating SDP relaxations for nonlinear
programming problems. As I am trying sdpa-gmp on the attached example: I am
getting a SIGFPE (floating point exception).
My machine is a MACbook laptop running OSX Yosemite. I am compiling
against the latest version of gmp (I believe 6.0.0)
Any help will be appreciated.
thanks,
Sriram

Dear Makoto Yamashita I think I have understood how sdpa-c works. Thank you very much. Alfredo |
