Have you tried increasing the value of lambdaStar in the parameter file? If you choose this parameter too small, then SDPA will start with a very small initial step size and runs into the problem that you describe.

When I try to compile SDPA-QD with GCC 11 I get the error "use of an operand of type ‘bool’ in ‘operator++’ is forbidden in C++17". This is very easy to fix, one just needs to replace the line LP_CNonZeroCount[blockNumber[l2]+j]++; in the file sdpa_io.cpp with LP_CNonZeroCount[blockNumber[l2]+j] = true; The same problem affects SDPA-GMP, and I assume all other versions of SDPA.

Hello! I think I am having some problems with installation of sdpa. I downloaded sdpa-7.3.8 and compiled it via ./configure and make, which seemed to succeed. But then I tried to run sdpa A.dat A.result where A.dat is the example downloaded from http://plato.asu.edu/ftp/sdpa_format.txt . In this example the following 4x4 matrix should be SDP: x1-1 0 0 0 ; 0 x1+x2-2 0 0 ; 0 0 5*x2-3 2*x2 ; 0 0 2*x2 6*x2-4 The output (copied below) does not make any sense to me. In particular, the solution xVec = {-4.414e+00,+6.121e+00}...

Dear Professor Yamashita, Dear all, Recently I tried to install SDPARA following the usual instructions. I have Open MPI 2.1.1 isntalled, with ScaLAPACK and BLACS, and I compiled MUMPS in the distribution version. When I'm trying to do "make", it gives me error messages of sorts: mumps_part9.F:(.text+0x18cb7): undefined reference to `mpi_allreduce_' ./mumps/build/lib/libmumps_common.a(mumps_part9.o): In function `mumps_645_': Could you please provide any advice on how to complete the linking process?...

Dear developers, I generated a .dat-s file from Ncpol2sdpa in python, and tried to solve it in SDPA, but no matter I used SDPA in Python or in Command line, the result from SDPA is a total blank. I checked the Task Manager in Windows while running sdpa.exe in command line. It normally takes lower than 50% of my CPU and Memories. But after few hours, the sdpa.exe didn't work anymore which was shown at the Task Manager. Thanks!

Dear Rui Li, When I compiled SDPA to build an Windows binary, I used mingw64 on a Linux machine. On Windows, I guess cygwin or msys2 are available to compile SDPA. Thanks, Makoto Yamashita

Rui Li posted a comment on discussion Open Discussion
Yeah. You're right. I also spent a half year to learn the documentation, technical points, and installation. I think updated documentation is necessary.

Hi all, Does anyone have experience on running the C++ SDPA code on a Window operating system? I transform from the Ubuntu system to a Window system. However, I encountered more than 100 errors when I was running the original code. Thank you. Regards, Ricky

Thanks a lot for the fix. We appreciate your support.

Dear Makoto, A fellow student has managed to fix the problem - by changing the timings.h file in spooles/build so that //static struct timezone TZ ; is commented out and gettimeofday(&TV, TZ) ; \ is replaced by gettimeofday(&TV, NULL) ; \ the MakeFile for spooles also needs to be editited, so that the files are not extracted from archive each time. - commenting out the line rm -rf build ; mkdir build ; cd build ; tar xvfz ../archive/spooles.2.2.tgz does this. this is because in the current version...

Thank you very much for your interst on SDPA. Now, timezone is defined in, for example, /usr/include/x86_64-linux-gnu/sys/time.h. Could you try #include </usr> ? Best Regards, Makoto Yamashita

Hello there, I am looking to use the QD variant of SDPA, and have been following the relevant installation instructions. I can install the QD library no problem, but when I try to make SDPA-qd I get the following error many times: ../../Utilities/MM.h:47:12: warning: format '%d' expects argument of type 'int', but argument 3 has type 'long unsigned int' [-Wformat=] "\n ALLOCATE error : bytes %d, line %d, file %s", \ ^ basics.c:27:1: note: in expansion of macro 'ALLOCATE' ALLOCATE(etree, struct _ETree,...

I found the SDPA-C solver usually fails to get the optimal solution due to some numerical issues while other solves like SeDumi can solve it efficiently. As the attached two data file. How could I fix it? SDPA-C performs Cholesky factorization to solve the Schur complement system, and this step is not easy to be parallelized. So, I am wondering is it possible to lever some iterative methods to replace Cholesky factorization to develop a parallel one. SDPA-C do not perform the Mehrotra predictor-corrector...

Dear all, I am writing regarding some trouble in prapreing the data file for the SDPA-C solver. Since SDPA-C embedded the sparse clique factorization into the PDIP method, my trobule is whether I need to obtain the Chordal graph and maximal cliques of the problem before putting the data file problem into the solver. If I do this, how the SDPA-C figure out this since the data file has on infromation on the clique facotirzation. If not, does the solver do this inside? Another question is the sparse-clique...

I have received an answer by mail which did not get picked up by SourceForge. It turned out that my Python 2 build was failing because I was missing the SPOOLES library. Python 3 support for SDPA-P has not been implemented so far.

Hi all, I just install the SDPA-C solver on ubuntu. However, I encountered a mistake when I execute the 'make all' command. Here is the screen output.

Hi all, I use the SDPA and Sedumi to solver a large sparse SDP. I found the Sedumi can solve the problem while SDPA told me that 'the step length is too small'. I am wondering is it possible for me to make SDPA to solve the problem by changing this condition? Best, Rui

Hi all, I am using the SDPA-C to solve a SDP problem on Liunx, however, I failed to install the SDPA-C, due to the targeted address: http://www.cise.ufl.edu/research/sparse/SuiteSparse/SuiteSparse-4.0.2.tar.gz is wrong. I am wondering how can I change this address. Thank you so much. Rui
