🌸 NAME 🌸

Bestie, welcome to the MPQC manual page for sc::R12IntsAcc_MPIIOFile(3) — yes, section 3, we love a manual-page moment. 💖

The star of this page is literally sc::R12IntsAcc_MPIIOFile.

• struct PairBlkInfo

💅 Public Member Functions 💅

• R12IntsAcc_MPIIOFile (Ref< MemoryGrp > &mem, const char *filename, int num_te_types, int ni, int nj, int nx, int ny) — constructor signature, no extra description listed in the original, bestie.
• R12IntsAcc_MPIIOFile (StateIn &) — the StateIn constructor signature, with no extra note attached.
• void save_data_state (StateOut &) — save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them.
• void store_pair_block (int i, int j, double *ints) — stores an ij pair block of integrals to the file. 🫶
• void commit () — commit the content of the accumulator for reading: deactivate the associated MemoryGrp and activate the accumulator.
• void activate () — call when ready to read content.
• void deactivate () — done reading content → activate the associated MemoryGrp. This is a collective operation.
• void release_pair_block (int i, int j, tbint_type oper_type) — releases an ij pair block of integrals.
• bool is_local (int i, int j) const — is this block stored locally?
• bool is_avail (int i, int j) const — in this implementation blocks are available everywhere.
• bool has_access (int proc) const — does this task have access to all the integrals?
• bool can_restart () const — can restart MPI-IO-based accumulator.
• int ij_index (int i, int j) const — signature only, no extra description listed in the original.

🛡️ Protected Member Functions 🛡️

• void check_error_code_ (int errcod) const — utility function to check MPI I/O error codes.
• void init (bool restart) — signature only, no extra description listed.
• int ntasks () const — total number of tasks.
• int taskid () const — ID of this task.

💖 Member Function Documentation 💖

💅 void sc::R12IntsAcc_MPIIOFile::commit () [virtual]

Commit the content of the accumulator for reading — deactivate the associated MemoryGrp and activate the accumulator. This is a collective operation.

Reimplemented from sc::R12IntsAcc.

💅 void sc::R12IntsAcc_MPIIOFile::save_data_state (StateOut &) [virtual]

Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them. This must be implemented by the derived class if the class has data.

Reimplemented from sc::R12IntsAcc.

Reimplemented in sc::R12IntsAcc_MPIIOFile_Ind.
