The machine is not registered on the DNS, you should use the IP address
You should request the account to the SPM teacher sending an email with
Once you have the account (will be an “spm15XX”) you may access the host with the Xeon PHI board by
You should change the password you received by email at first login issuing a command passwd at the shell prompt.
Please take into account the homes on r720-phi.itc.unipi.it are not subject to backup. Keep a local copy of whatever (source) files you are using on the machine. In case of problems I'll not be able to recover any of the home files.
Take into account that you may edit files on your machine and just compile and run them on the remote (host or PHI). What you can do is to have a local directory hosting the source files, may be develop and debug using local IDE (such as Eclipse or Visual Studio), then synchronize the files using the rsync command and execute commands on remote host via ssh commands from the shell prompt.
If you need further info concerning the procedure don't hesitate to ask me during question time or by email.

The correct version of FastFlow to use for the course is actually replicated under
/home/spm1501/fastflow
and the exercises and material relative to the classworks are under
/home/spm1501/public
In case you want to access directly these directories under your own home directory, you may create symbolic links to the two directories by issuing commands such as:
link -s /home/spm1501/fastflow . link -s /home/spm1501/public .
that will leave two new subdirectories (link) in the current directory.
All the non standard tools (or the versions newer than the ones provided in the standard distribution) are available under the directory
/home/spm1501/public
Oracle JDK 1.8 has been installed under /home/spm1501/public directory. Set up the PATH to the bin directory and please avoid to make local copies of it in your local home directory. Both compiler and run time have been installed. This only works on the host, it does not work on the Xeon PHI.
In order to be able to use the tools, you have to run the script in
In order to run a program on PHI:
Please take into account that a minimal set of libraries is available on the mic.
There are a few things to take into account when using FastFlow on PHI:
-DNO_DEFAULT_MAPPING
when compiling FastFlow programs, as the default mapping at the moment assumes a core numbering such as the one used for Sandy/Ivy Bridge (0 first context of the first core, 1 first context of the second core …) processors, which is different from the one used on PHI (0 first context of the first core, 1 second context of the first core …).
-O3
to compile FastFlow code
/home/spm1501/fastflow
that is use the compile time flag
-I /home/spm1501/fastflow
You can use both the accelerators available on the machine (namely MIC0 and MIC1), despite the fact the examples in this page alway use mic0 …
