ICTP is one of the mathematical institutes coordinated by the Section of Mathematical Sciences of the Romanian Academy; the Institute does not have legal personality, and is administered by the Cluj-Napoca Branch of the Romanian Academy.
The abbreviation ICTP comes from the Romanian name of the institute: Institutul de Calcul “Tiberiu Popoviciu”.
In 1951, the Romanian Academy founded the Mathematical Section of the Cluj-Napoca Branch of the Romanian Academy, formed by the members of the Seminar on Numerical Analysis founded by T. Popoviciu; the Section was located in the building from no. 37, Republicii St.
In 1957, the Romanian Academy transformed the Section into the “Institutul de Calcul”, with legal personality.
Apart of research in mathematics, the Institute made intensive and cutting edge explorations in electronics. Three computers were built here from scratch (MARICA, DACICC-1, DACICC-200), between 1957-1968.
The Institute became one of the leaders in electronics in Romania obtaining here:
- patents (e.g., regarding integrated circuits by diffusion)
- ionic implanted chips
- numerous contracts with other leaders in electronics (IPRS Baneasa – Bucharest)
The expertise in Numerical Analysis gained here lead to numerous contracts with the industry and agriculture from our country, bringing consistent benefits (up to ten $million).
Most of the main technical institutes of Romania benefited of the trainings on computer programming organized by the Institute (a partial list is here).
Numerous highschools across the Romania sent pupils to see the computers made at the Institute and to learn Computer Science.
Due to international connections with different authors, the Institute had an updated library, containing numerous books and journals. The students and mathematicians from this part of the country benefited of this facility (see here a list of approvals for loaning books).
At present, the main research directions reside in Numerical Analysis.
Several notable Romanian journals were edited here:
- Studii şi Cercetări Matematice (Cluj) – between 1957-1963
- Revista de Analiza Numerica si Teoria Aproximatiei – between 1972-1974
T. Popoviciu and other members of the Institute had notable contributions in the editing of the journal Mathematica, under the auspices of the Romanian Society of Mathematical Sciences (SSMR), Cluj-Napoca Branch (lead by T. Popoviciu between 1958-1975).
At present, the Institute coordinates the editing of the journal Journal of Numerical Analysis and Approximation Theory (JNAAT), published by the Romanian Academy Publishing House.
ICTP has a library with more than 25.000 books and journals, and some computing facilities (a server and several workstations).
The Institute has established an important cooperation agreement with Forschungszentrum Jülich (Germany), which allows the access to supercomputing facilities and the realization of important numerical applications.
