It can be useful for others to try different gfortran.Īs I have a dual-boot W8/Ubuntu-12.10 (both 64 bits) on my machine, I’ve made some tests with the two configurations : corei5 2,3GHz (2 cores and 4 logical processors) and 4 GB RAM.Ĭonfig 1 : Windows 8 64 bits/python 2.7/MPICH2 1.4.1/gfortran 4.8.0Ĭonfig 2 : Ubuntu 12.10 64 bits/python2.7/Openmpi 1.6.4/gfortran 4.8.0 Then, I’ve found another version which works well with my configuration : (I’ve used the gcc-4.8.0-64.exe). I’ve encountered some difficulties with the two gfortran versions you’ve provided in your posts (#8601 and #8694). I’ve succeeded in compiling Telemac in parallel on windows 8 (64bits) with gfortran. installed: place the mpich2/bin folder in the environment variable PATH before the e.g. if you have Matlab or other parallel processing software with mpiexec etc. don't worry if the command mpiexec -validate fails, for mpiexec use the flag -localonly in the systel.cfg configuration file. give manually the relevant GCC bin directory to the environment variable PATH don't mix different Gfortran installations Some hints which could help for a local machine configuration: However the link for the GCC suite provided by Cyamin works also. During the installation one has to activate the button to install the Gfortran compiler additionally. I used the GCC 4.7.1 compiler suite from / which has a user friendly installer. In the parallel mode the computation times in both cases are approximately 40% lower. Spillway with 15000 elements and Malpasset Large validation case with 104000 elements. I tested two case studies on my Win7 64 bit local machine with Gfortran, 2*Intel Pentium D 3.00 GHz, in scalar and parallel mode (2 cores).
