I now work for Bull, which is now part of Atos. My current professional address is of the standard pattern: "firstname.lastname at atos dot net" (it used to be "firstname.lastname at bull dot net").
During my times in the now-defunct CAPS entreprise, I wrote an introduction to the kind of things I do, entitled An Introduction to Performance Programming. It was published on the web at the time by HPC magazine, which is now HPC Today in French: Programmer pour la performance (1ere partie) and Programmer pour la performance (2eme partie) and in English: An Introduction to Performance Programming (part I) and An Introduction to Performance Programming (part II)
A frequent question in my field is how to compute the Theoretical peak FLOPS per instruction set. You can view the online view-only version here (may be browser-dependent). An older, less complete version of this paper was available in two parts: Theoretical Peak FLOPS per instruction set on modern Intel CPUs and Theoretical Peak FLOPS per instruction set on less conventional hardwareLinkedIn profile
