Hi Barry, <br></div><div dir="ltr"><br>fftw-configure fails on login node. I'm attaching the error message at
the bottom of this email. I tried request 1 hour of time on a compute
node to compile fftw on it but for some reason 1 hour is not enough to
compile fftw, hence I was forced to use cray-fftw-3.3.8.1 for which I
had no control over though the manpage gives a lower limit for
compiler/MPT/craype versions which I'm not violating. <br><br><br>```<br>sajid@thetalogin5:~/packages/petsc>
