bandwidth is a benchmark to estimate the memorybandwidth of a system, including main memory, L2 cache, framebuffer memory, and string library performance.License: GNU General Public License (GPL)Changes:
Core tests have been converted to assembly code to improve accuracy. This release has switched to microsecond timing for improved accuracy. L1 cache tests have been added.
Hi,
I'm looking for some way to bring up in a shell window a realtime (or something that updates at 10 second intervals or whatever) bandwidth monitor.
I just want something that shows me how much kbps is going in and how much is going out of each interface. Is there something that might... (2 Replies)
i have two questions actually...
i need to block certain ports with openbsd and PF in a large lan, the firewall is supposed to be a router between the internet and the first lan switch.
first of all, would this work at all in theory?
second, i tried doing this a few days ago at a huge lan but i... (2 Replies)

NAME
CLASCL - multiplie the M by N complex matrix A by the real scalar CTO/CFROM
SYNOPSIS
SUBROUTINE CLASCL( TYPE, KL, KU, CFROM, CTO, M, N, A, LDA, INFO )
CHARACTER TYPE
INTEGER INFO, KL, KU, LDA, M, N
REAL CFROM, CTO
COMPLEX A( LDA, * )
PURPOSE
CLASCL multiplies the M by N complex matrix A by the real scalar CTO/CFROM. This is done without over/underflow as long as the final result
CTO*A(I,J)/CFROM does not over/underflow. TYPE specifies that A may be full, upper triangular, lower triangular, upper Hessenberg, or
banded.
ARGUMENTS
TYPE (input) CHARACTER*1
TYPE indices the storage type of the input matrix. = 'G': A is a full matrix.
= 'L': A is a lower triangular matrix.
= 'U': A is an upper triangular matrix.
= 'H': A is an upper Hessenberg matrix.
= 'B': A is a symmetric band matrix with lower bandwidth KL and upper bandwidth KU and with the only the lower half stored. =
'Q': A is a symmetric band matrix with lower bandwidth KL and upper bandwidth KU and with the only the upper half stored. = 'Z':
A is a band matrix with lower bandwidth KL and upper bandwidth KU.
KL (input) INTEGER
The lower bandwidth of A. Referenced only if TYPE = 'B',
KU (input) INTEGER
The upper bandwidth of A. Referenced only if TYPE = 'B',
CFROM (input) REAL
CTO (input) REAL The matrix A is multiplied by CTO/CFROM. A(I,J) is computed without over/underflow if the final result
CTO*A(I,J)/CFROM can be represented without over/underflow. CFROM must be nonzero.
M (input) INTEGER
The number of rows of the matrix A. M >= 0.
N (input) INTEGER
The number of columns of the matrix A. N >= 0.
A (input/output) COMPLEX array, dimension (LDA,M)
The matrix to be multiplied by CTO/CFROM. See TYPE for the storage type.
LDA (input) INTEGER
The leading dimension of the array A. LDA >= max(1,M).
INFO (output) INTEGER
0 - successful exit <0 - if INFO = -i, the i-th argument had an illegal value.
