Running dedicated on AIX with 4 processors, creating 4 threads, each with equal work to do, only runs about 20% faster than 1 thread with all of the work. Test case has no blocking but does share memory for read access only.
Any ideas why I'm only seeing 20% gain? Is this typical on AIX? ... (1 Reply)
I am trying to analyze the performance of an AIX system. I think I may have a disk I/O issue, but I am asking for help to validate or invalidate this assumption. I ran the commands below during a period of peak load.
Please help me to find any performance bottlenecks. Thanks in advance for your... (15 Replies)
Hello,
I run my pthread code on Linux with 4 processors. However, the speed up is only 2 times.
The code is about solving equation (G+s(i)C)z(i)=B*us(i), i=1,...,n. Here G,C are m*m matrix, B*us(i) is a m*1 vector and s(i) are n different numbers. I need to solve the equation n times to... (1 Reply)
A few of our machines need upgrading and we are looking into a selection of processors at present. There are suggestions on the vendor's websites that the L3 cache was specifically introduced for gamers. Is this true? Does having L1, L2 and/or L3 cache help at all in performance or are the...

or
server # tar –cf – . | rsh client ‘cd target && tar –xv -f –‘
I think it doesn't really matter because both command strings involve a tar being run on the... (1 Reply)

SYNOPSIS
install-solaris
install-solaris invokes the Solaris Install program. Depending on graphical capability and available memory at the time of invocation,
install-solaris invokes either a text-based installer or a graphical installer.
The following minimum requirements for physical memory dictate which features are available during installation:
For SPARC machines:
128 MB
Minimum physical memory for all installation types
128 MB
Minimum physical memory required for windowing system
384 MB
Minimum physical memory required for graphical-based installation
For x86 machines:
256 MB
Minimum physical memory for all installation types
256 MB
Minimum physical memory required for windowing system
512 MB
Minimum physical memory required for graphical-based installation
In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number of fea-
tures available.
install-solaris exists only on the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the for more
details.
install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
