spectre error (64bit/32bit) on linux

This looks as if you've not got one of the relevant shared libraries available on the machine.

First of all, I assume you're running on a 64-bit OS. We don't support 32-bit OS for some time - and spectre pretty much requires you to be on a 64 bit OS for at least some parts of the flow. The actual simulator can be run as 32 bit (the default normally) or 64 bit - this is a tradeoff between performance and capacity. The 32 bit simulator will be slightly faster than the 64 bit, but can't access any more than about 3.7Gbytes of memory (it's faster because there is less memory accessed because the pointers are 4 bytes rather than 8 bytes).

Which version is used may be controlled by the $CDS_AUTO_64BIT UNIX env var, or via a setting on the Setup->Environment form in ADE.

Now for that missing shared library. On my RHEL5.5 system (so should be similar) I have both the 32 bit and 64 bit version of readline installed:

UNIX$ rpm -q -f /usr/lib64/libreadline.so.5
readline-5.1-3.el5

So the package name is readline-5.1.3.el5 (there may be a newer version - the key thing is that the rpm is called "readline"). I suspect on your RHEL6 machine if you do:

UNIX$ rpm -q readline
readline-6.0-4.el6.x86_64
readline-6.0-4.el6.i686

(on my RHEL5 machine I don't get the different suffix for the two different versions, one 64 bit, one 32 bit).

So I think you just need to get the missing RPM installed.

Hi Andrew,

Thanks for the reply.

I ran "echo $CDS_AUTO_64BIT" and it returns "CDS_AUTO_64BIT: undefined variable", I looked at Setup->Environment, Run with 64 bit binary is not checked.

I'm using RHEL5,  64bit OS.  You're right, when I ran, "UNIX$ rpm -q -f /usr/lib64/libreadline.so.5", I got "readline-5.1-3.el5". (when I ran  UNIX$ rpm -q readline, I got  "readline-5.1-3.el5" twice) I was concerned about installing the package because this issue happens only to me, not other co-workers who's running from the same server (unless they all changed some settings which I doubt), also CAD ppl could get mad in case I messed up things..

I nevertheless downloaded one from internet and ran it "rpm -ivh readline-5.1-3.el5.x86_64.rpm", but got warning of "readline-5.1-3.el5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 82fd17b2" and error of "can't create transaction lock on /var/lib/rpm/__db.000"

Could it be that some settings/env var got accidentally changed only on my side? I'm just guessing.

thanks,

Kevin

If that environment variable isn't set - you should check the runSimulation script to see if it has -64 specified on the command line for spectre.

I can't see how it would not find the libreadline.so.5 on the machine if it is present, unless $LD_LIBRARY_PATH is set to something strange and is omitting /lib - but then various things might fail in that case. Even then I think the wrapper takes care of it - so that works.

Probably best if you contact customer support. Guesswork via the forum isn't a particularly effective way of diagnosing the problem! Us being able to look at the setup with you is much more likely to get to the bottom of it.

Regards,

Andrew.
