1. A centralized mailhost (mailhost.tifr.res.in) receives and stores/forwards emails which may be accessed via POP or IMAP servers. A webmail service https://mailhost.tifr.res.in allowing access to email via web browsers is also available.
2. A MAIL service (tifrmail.tifr.res.in), receives emails from DATANET only. A webmail service https://tifrmail.tifr.res.in allowing access to email via web browsers is available.
A dedicated web server www.tifr.res.in provides a platform for hosting institute, departmental and personal web pages.
Apache webserver 2.4.37
PHP 7.4.16 with the following extensions enabled
Java JDK 1.8.0_265
Python 2.7 and 3.2
A centralized FTP server ftp.tifr.res.instores user data.which may be accessed via Internet Web browser.
Files under every user's home directory are publically accessible to other users in this server. Any one who wants to protect his directories can set permission using command: chmod 700 . (the 'dot' at end)
A centralized SSL-VPN service (For Windows/MAC: https://sslvpn.tifr.res.in/winuser; For Linux: https://sslvpn.tifr.res.in/linuxuser configuration is to have a single main internal network with remote nodes using VPN to gain full access to the TIFR net. The remote nodes are commonly remote employees working from other than TIFR network.
cchpc12 cluster configuration is: 3.3 GHz, 32 cores (Physical cores only), 6 nodes. (P7 is capable of doing 8 operations per cycle)
(a) peak theoretical
Peak performance = CPU clock speed * no. of cores * no. of nodes * operations per cycle
So, Peak performance = 3.3 GHz * 32 * 6 * 8 = 5068.8 Gflops (ie., 5.0688 TFlops)
(b) on linpack
We obtained the sustained performance of 3.616 TFlops (71.33 % of peak)
