HPL_pdpanel_init(3)

💖 HPL_pdpanel_init — bestie edition 💖

okay so this is a page from the HPL manual (that's the High-Performance Linpack library, and yes she's iconic), and today we're talking about HPL_pdpanel_init(3) 🎀

---

✨ NAME ✨

HPL_pdpanel_init — she initializes the panel resources. that's it, that's the whole job, and she does it flawlessly 💅

---

🌸 SYNOPSIS 🌸

#include "hpl.h"

void HPL_pdpanel_init( HPL_T_grid * GRID, HPL_T_palg * ALGO, const int
M, const int N, const int JB, HPL_T_pmat * A, const int IA, const int
JA, const int TAG, HPL_T_panel * PANEL );

like look at her. ten arguments. no notes. 👑

---

🦋 DESCRIPTION 🦋

so HPL_pdpanel_init initializes a panel data structure. that's the vibe. that's what she's here for. ✨

---

💜 ARGUMENTS 💜

bestie, there are a LOT of them, so buckle up, we're going through every single one, no skipping, fr fr 🙈

• GRID — (local input) HPL_T_grid * on entry, GRID points to the data structure holding all the process grid information. that's the whole squad map right there. 🌈
• ALGO — (global input) HPL_T_palg * on entry, ALGO points to the data structure with the algorithmic parameters inside. the rules of the game, periodt. 📋
• M — (local input) const int on entry, M specifies the global number of rows of the panel. and bestie, M must be at least zero. don't try anything funny. 😤
• N — (local input) const int on entry, N specifies the global number of columns of the panel and trailing submatrix. and yes, N must be at least zero too. no negatives allowed, we don't do that here. 💀
• JB — (global input) const int on entry, JB specifies is the number of columns of the panel. (yes the original says "specifies is", we love her anyway 💖) and JB must be at least zero.
• A — (local input/output) HPL_T_pmat * on entry, A points to the data structure containing the local array information. she's both input AND output, main character energy, she reads and she writes. 👑
• IA — (global input) const int on entry, IA is the global row index identifying the panel and trailing submatrix. IA must be at least zero. always. every time. 💅
• JA — (global input) const int on entry, JA is the global column index identifying the panel and trailing submatrix. JA must be at least zero. same energy, different axis. ✨
• TAG — (global input) const int on entry, TAG is the row broadcast message id. that's her whole personality, she's a message id, and she ate. 🔥
• PANEL — (local input/output) HPL_T_panel * on entry, PANEL points to the data structure containing the panel information. another input/output girlie, she's getting filled in with all the good stuff. 🫶

also a lil heads up bestie: A and PANEL are both local input/output, so they're getting modified. the rest are just vibes coming in. 🌸

okay that's the whole page!! this one came straight from HPL 2.2, dated February 24, 2016, so she's an older queen but she still slays 💅✨ thanks for reading bestie, go initialize some panels, mwah 🎀💖🦋
