Dear XMM HelpDesk: We are defining our needs to be able to deal with XMM data, and we would like to know from you what will be the hardware requirements to be able to run your analysis software. More specifically: 1. At you web site (http://astro.estec.esa.nl/XMM/xmm_sas.html) I saw that the software will be designed to run on a Sun Sparc under Solaris (version TBD, but not earlier than 2.5). Does this still hold? Do you plan to include any other platform? 2. Will you provide the binaries for that (those) platform(s) (Sun Solaris, others?), or will you provide the source and the user will have to compile it locally? 3. If users will have to compile the sources, will you still use the NAG Fortran-90 compiler, despite that NAG has released the Fortran 95? I saw your note for the Sun F90 compiler (might be supported at a later date, if future versions include support for 1 and 2 byte integers). I don't know if for the latest Sun F90 (v5.0, I believe) this is already the case but if not, will we need to have NAG F90 (or F95)? 4. How much RAM memory would be needed to run your software "comfortably"? Thanks in advance. Best regards, -Mariano Mendez. -- Mariano Mendez mariano@astro.uva.nl

Dear Mariano, The XMM-Newton Mission Scientist has forwarded to me the following message, which is intended to answer your questions 1., 2. and 4. Your question 3. has been forwarded to the SAS SOC developers team. I will forward their answer to you as soon as it is delivered. The platform support for the SAS is as follows : 1. Officially supported - Solaris 2.6 - Solaris 7 (In the near future) 2. Supported on a best-efforts basis (In practice this means a compiled recent version will almost always be available) - Linux (only Redhat; > 5.2) - Digital UNIX/DEC OSF (version depends on external resources we use for building the SAS). The minimum hardware platform recommended is : - SUN ULTRA Sparc 60 (2 CPU's) > 512 MByte memory > 20 GByte of disk space. The SAS will be distributed in the following formats : 1. .tar.gz for Solaris, Digital Unix and Linux 2. Solaris package format (near future) 3. .rpm for Linux (near future) 4. Sources Building the SAS from sources is NOT a recommended procedure and currently takes >7 hours on a 4 CPU Enterprise 450. The resources + S/W versions required to build the SAS from source files will eventually be made public on the XMM WWW pages at VILSPA. The SAS is written in C, C++ and F90/F95, it requires a number of public domain packages in support (FTOOLS, DS9 etc.) which are detailed in the release notes. The SAS user is responsible for a proper installation of the correct version of the SAS supporting packages. Best Regards, Matteo Guainazzi XMM-Newton SOC User Support Group

Dear Mariano, the SOC SAS deveopers team responsible sent to me the following answer to your question 3. We are not aware of any problems using NAG f90. However, you cannot buy a f90 compiler from NAG any longer, only a f95 one. All the SAS developers use f95 (from v4.0 patchlevel 154 to v4.0a patchelevel 304). It isn't clear that we shall ever be able to support any other f95 compiler, because the SAS can only work if the fortran compiler C interface is public. Only NAG makes that specification available.
