[Octave-bug-tracker] [bug #40304] Excessive I/O in load function

[anonymous]

Follow-up Comment #4, bug #40304 (project octave):

Answering both questions:

- The input file is text. There was a small script from a user - it looks like
they're loading in a text file in order to convert the data to matlab format.

- The version I pulled with Mercurial advertises itself as 3.7.7+. It shows
the same odd behaviour as 3.6.4:

32080 open("Extended_Molecule", O_RDONLY) = 3
32080 read(3, "# name: nspinn# type: scalarn   "..., 8191) = 8191
32080 lseek(3, -8162, SEEK_CUR)         = 29
32080 read(3, "   1n# name: FermiEn# type: scal"..., 8191) = 8191
32080 lseek(3, -8156, SEEK_CUR)         = 64
32080 read(3, "    -3.41540n# name: iorbn# type"..., 8191) = 8191
32080 mmap(NULL, 262144, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0x7f6390c4b000
32080 lseek(3, -8120, SEEK_CUR)         = 135
32080 read(3, "   1   2   0   0   1n   1   2   "..., 8191) = 8191
32080 lseek(3, -8187, SEEK_CUR)         = 139
32080 read(3, "   2   0   0   1n   1   2   0   "..., 8191) = 8191
32080 lseek(3, -8187, SEEK_CUR)         = 143
32080 read(3, "   0   0   1n   1   2   0   0   "..., 8191) = 8191
32080 lseek(3, -8187, SEEK_CUR)         = 147
32080 read(3, "   0   1n   1   2   0   0   2n  "..., 8191) = 8191
32080 lseek(3, -8187, SEEK_CUR)         = 151
