If you have problems during the execution of MRCC, please attach the output with an adequate description of your case as well as the followings:
  • the way mrcc was invoked
  • the way build.mrcc was invoked
  • the output of build.mrcc
  • compiler version (for example: ifort -V, gfortran -v)
  • blas/lapack versions
  • as well as gcc and glibc versions

This information really helps us during troubleshooting :)

Dear developers I am using MRCC 2022 with the various patches for this computation. I get the following error when I attempt to do a CCSDT(Q)_L computation. It completes the CCSDT portion and attempts to solve the left hand portion. I've attached the output file.Starting left-hand LR-CC iteration for root                      1 ... ======================================================================forrtl: severe (174): SIGSEGV, segmentation fault occurredImage              PC                Routine            Line        Sourcemrcc               0000000001280CDA  Unknown               Unknown  Unknownmrcc               000000000126EB10  Unknown               Unknown  Unknownmrcc               00000000004ACFA7  Unknown               Unknown  Unknownmrcc               0000000000446CCA  Unknown               Unknown  Unknownmrcc               00000000004414CE  Unknown               Unknown  Unknownmrcc               000000000043498D  Unknown               Unknown  Unknownmrcc               00000000004062B6  Unknown               Unknown  Unknownmrcc               0000000000400DF2  Unknown               Unknown  Unknownmrcc               000000000135DEB9  Unknown               Unknown  Unknownmrcc               0000000000400CCA  Unknown               Unknown  Unknown

I could not reproduce this. It is running smoothly with the latest MRCC version, at least on 4 CPU cores. Can you please try it with the latest version?

Best regards,
Mihaly Kallay

It seems to be working with MRCC 2023 and the patches. I'll test a few of the computations I did with 2022 to see if they get similar results with the new version. It is currently running with 16 openmp cores.
