load (ld.c) instructions that reach retirement. Counts only

 

retired floating-point instructions.

INST_CHKA_LDC_ALAT.INT

The number of all advanced check load (chk.a) and check

 

load (ld.c) instructions that reach retirement. Counts only

 

retired integer instructions.

INST_FAILED_CHKA_LDC_ALAT.FP

The number of failed advanced check load (chk.a) and

 

check load (ld.c) instructions that reach retirement. Counts

 

only failed floating-point instructions.

INST_FAILED_CHKA_LDC_ALAT.INT

The number of failed advanced check load (chk.a) and

 

check load (ld.c) instructions that reach retirement. Counts

 

only failed integer instructions.

Percent data speculation miss

Percentage of retired chk.a /ld.c instructions that failed.

Percent float advanced check load

Percentage of floating-point chk.a /ld.c floating-point

 

instructions, with respect to all chk.a /ld.c instructions.

Percent integer advanced check load

Percentage of retired chk.a /ld.c integer instructions that

 

failed.

Percent failed float advanced check

Percentage of floating-point chk.a /ld.c failed instructions

load

with respect to all chk.a /ld.c failed instructions.

Percent integer advanced check load

Percentage of integer chk.a /ld.c instructions with respect

 

to all chk.a /ld.c instructions.

Percent float ALAT miss

Percentage of floating-point components in all the misses

 

incurred by instructions accessing the ALAT.

Percent integer ALAT miss

Percentage of integer components in all the misses incurred

 

by instructions accessing the ALAT.

Advanced check load per kinst

The number of data speculation events per 1000 retired

 

instructions.

Failed advanced check load per kinst

The number of data speculation fail events per 1000 retired

 

instructions.

% of cycles lost due to stalls

Percent of cycles lost due to stalls.

% Core cycles due to this thread

This indicates the percentage of available processor cycles

 

that the measured process consumed. The other processor

 

cycles were consumed by other process(es) running in the

 

core's other hyperthread or were lost to HyperThreading

 

overhead.
