sc::R12IntsAcc_MemoryGrp(3)

💅 sc::R12IntsAcc_MemoryGrp — from the MPQC manual, bestie 💖

Okay so this is a page from the MPQC manual (section 3, which means it's a library function, iykyk) and honestly? It's giving "I hold all your integrals in a MemoryGrp and I will be dramatic about it." Let's get into it. ✨

🌸 NAME 🌸

sc::R12IntsAcc_MemoryGrp — your girl for accumulating R12 integrals on top of a MemoryGrp. Periodt. 💅

---

🎀 SYNOPSIS 🎀

The whole vibe: it inherits sc::R12IntsAcc. That's the family tree, no cap.

class sc::R12IntsAcc_MemoryGrp : public sc::R12IntsAcc

✨ Public Member Functions ✨

Here's the full roster, bestie — every single one, in order, nothing skipped:

• R12IntsAcc_MemoryGrp (Ref< MemoryGrp > &, int num_te_types, int ni, int nj, int nx, int ny) — the constructor that takes a MemoryGrp reference plus num_te_types, ni, nj, nx, ny. That's it, that's the whole signature. 🫶
• R12IntsAcc_MemoryGrp (StateIn &) — constructor that restores from a StateIn. Comeback era. 🔥
• void save_data_state (StateOut &) — saves the base classes (via save_data_state) and the members in the same order the StateIn CTOR initializes them. Order matters, don't play with me.
• void store_memorygrp (Ref< MemoryGrp > &mem, int ni, const size_t blksize) — stores all pair block of integrals held in mem. And listen: mem must be the same as mem_ used to construct this thing. Also it's a collective operation, so everybody participates, no lurkers. 👀
• void store_pair_block (int i, int j, double *ints) — stores an ij pair block of integrals. Heads up: it assumes the block already resides locally. 🏠
• void deactivate () — you're done reading content, so call set_localsize(0) on the associated MemoryGrp. Also a collective operation. 💫
• double * retrieve_pair_block (int i, int j, tbint_type oper_type) — retrieves an ij pair block of integrals. Hand it over. 🤲
• void release_pair_block (int i, int j, tbint_type oper_type) — releases an ij pair block of integrals, if needed. Bye bestie 👋
• bool is_local (int i, int j) const — is this block stored locally? Simple yes/no moment.
• bool is_avail (int i, int j) const — in this implementation, all blocks are globally available. Lucky us. 🌈
• bool has_access (int proc) const — does this task have access to all the integrals? Big question, honestly.
• bool can_restart () const — cannot restart MemoryGrp-based accumulator. Tragic, but true. 😭
• int ij_index (int i, int j) const — gives you the ij index.
• int ij_proc (int i, int j) const — gives you the ij proc.

🦋 Additional Inherited Members 🦋

There are more members inherited from the base class. They're not listed out here, but they exist, and they're living their best life in sc::R12IntsAcc. Go look, iykyk. 💜

Grab a snack, we're going deep on the important ones. 🍓

🧚 void sc::R12IntsAcc_MemoryGrp::deactivate () [virtual]

You're done reading content — so call set_localsize(0) on the associated MemoryGrp. It's a collective operation, so everyone's doing it together.

And this is the part where I hold your hand: this accumulator cannot be activated again. Like, ever. It's a one-way door. Do not come back asking. 💀

Reimplemented from sc::R12IntsAcc.

🧚 void sc::R12IntsAcc_MemoryGrp::save_data_state (StateOut &) [virtual]

Saves the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them. Matching order is the whole entire point, okay?

And fr fr: this must be implemented by the derived class if the class has data. Non-negotiable. 👑

Reimplemented from sc::R12IntsAcc.

🧚 void sc::R12IntsAcc_MemoryGrp::store_memorygrp (Ref< MemoryGrp > & mem, int ni, const size_t blksize) [virtual]

Stores all pair block of integrals held in mem.

Okay so important detail: mem must be the same as mem_ used to construct this. Same one. No substitutes, no swaps. 🙅‍♀️

This is a collective operation — everybody in.

Want more info? It says to see the documentation for R12IntsAcc::store_memorygrp(). So go see it. 🫡
