<p>Hmmmm, this is tricky. Based upon the links below it looks like essl uses non-standard lapack versions.</p>

<p>To handle this, I see two options:<br>
a) Someone with access to essl works (i can help) to add "#ifdef essl" to the mixer routines. Since I have no access to aix/essl I cannot do this.<br>
b) You, and perhaps others switch to standard lapack for the mixer.</p>
<p>I believe essl should conform to the published standard.</p>
<p>N.B., there may be a problem if essl decides to do its own error handling with, for instance, eigenvalues of singular matrices. These are supposed to fail and if essl crashes out the mixer will fail.</p>
<p>N.N.B. In emergency you can try regressing to MSEC1 although this is not as good as MSR1 & MSR1a. This will let you know if the other codes are working.</p>
