GHz, this is a read BW of 384 GB/s – higher than the full socket bandwidth of 307.2 GHz, 1530 GB/s peak BW from 6 HBM stacks), I see single-thread sustained memory bandwidth of 304 GB/s on the ReadOnly benchmark used here. Are these “good” improvements? At a single-core frequency of 3.0 On a VE20B (8 cores, 1.6

READ: bw=506MiB/s (531MB/s), 506MiB/s-506MiB/s (531MB/s-531MB/s), io=14.8GiB (15.9GB), run=30031-30031mse. WRITE: bw=491MiB/s (515MB/s), 491MiB/s-491MiB/s (515MB/s-515MB/s), io=14.4GiB (15.5GB), run=30030-30030msec.

READ: bw=507MiB/s (532MB/s), 507MiB/s-507MiB/s (532MB/s-532MB/s), io=29.7GiB (31.9GB), run=60063-60063msec. However we are able to achieve the advertised bandwidth from the spec sheet of 540MB/s with an outstanding IO of 8. So we can conclude that we don’t need 1024K per transfer to maximize throughput on this particular device.

Should the inline asm promote the “i1” to “i32” during ISEL? Should it be promoted during inlining? Is there a situation where we require the value to be “i1”? -bw. typedef _Bool bool ; static inline. __attribute__ (( __always_inline__ )). bool bar ( bool loc ) {. asm ( " quad 42 + %c0 -. int foo ( void ) {.
