Re: [petsc-users] BDDC assembly question

Hi Stefano I used case B) to not change the current code significantly. Nevertheless case A) is worth to look when the number of domains grow. In case B) I noticed that the l2g passing to MatSetLocalToGlobalMapping must also contain the off-proc entries, in order to assemble correctly. As you

Re: [petsc-users] slepc trap for large matrix

This option belongs to PETSc's configure, not SLEPc's configure. Jose > El 7 jun 2017, a las 16:37, Kannan, Ramakrishnan escribió: > > Barry, > > Thanks for the kind response. I am building slepc 3.7.3 and when I configure > –with-64-bit-indices=1, I am getting the following

Jose, I am running in the super computer environment. I just do a “module load cray-petsc-64/3.7.4.0”. I don’t compile PETSc. -- Regards, Ramki On 6/7/17, 10:41 AM, "Jose E. Roman" wrote: This option belongs to PETSc's configure, not SLEPc's configure. Jose

Barry, Thanks for the kind response. I am building slepc 3.7.3 and when I configure –with-64-bit-indices=1, I am getting the following error. ./configure --with-64-bit-indices=1 --prefix=/lustre/atlas/proj-shared/csc209/ramki/slepc ERROR: Invalid arguments --with-64-bit-indices=1 Use -h for

Re: [petsc-users] BDDC assembly question

Which version of PETSc are you using? If you use the dev version and try to call MatSetValues on a MATIS with a non-owned (subdomain-wise) dof it will raise an error, as MATIS does not implement any caching mechanisms for off-proc entries. Off-proc entries are a concept related with the AIJ

Re: [petsc-users] "snes/examples/tutorials/ex1f -snes_type fas" fails with segfault

Hello Nicolas, I ran snes/examples/tutorials/ex1f -snes_type fas with a recent version (3.7.6) and I confirm the problem. The C version works fine, but the Fortran version complains about a Fortran callback problem. My output looks quite similar to yours ... Best regards, Natacha mpirun ex1f

[petsc-users] Strange Segmentation Violation error

Hi, I have been PETSc together with my CFD code. There seems to be a bug with the Intel compiler such that when I call some DM routines such as DMLocalToLocalBegin, a segmentation violation will occur if full optimization is used. I had posted this question a while back. So the current
