ACML v. 2.6.0

Accelerated Computing HPC Compilers Legacy PGI Compilers
1

Our sys guy installed the acml library and I was asked to test it…note, we have v. 5.2
for PGF/CC…do the failures below require we upgrade ? Only the lapack stuff in the 32 bit
tests work as expected.

The pgi32 and pgi32_mp fft examples fail to compile (makefile as provided):

Hi Peter,

The 6.0 release includes some new faster math intrinsic functions. Because ACML 2.6.0 was built with 6.0 and compiled with “-fast -Mscalarsse -Mvect=sse”, the new intrinsics are used. So yes you must use the 6.0 compilers with ACML 2.6.0.

We do include the ACML 2.1 library (serial only) with the 5.2 release so if you just need an ACML library and not 2.6.0 in particular, you can use the included version.

Well, microway sold us PGI Workstation for 64/32 bit Academic version ($699$) and
1 year subscription ($220), i.e., no media, but “forgot” to install the acml.

In any case, does our purchase of the software/subscription include upgrading to version
6.0-4 ?

Thanks,
Peter

Yes, customers with current subscriptions can upgrade to 6.0 at no additional cost. Please contact sales@pgroup.com for the specifics about your account. Be sure to include you PIN number.

Thanks,
Mat

If we upgrade, will we have to recompile mpich and the rest of the stuff compiled
with v. 5.2 ?

Thanks,

Most likely.
